**Fix**
Wrap BuiltinCommands.setParser with Act.requireSession(...).
This makes the parser fail gracefully when no session is available, matching the behavior of other session-dependent parsers.
**Summary**
This adds an --append flag to the dependencyTree input task when used with --out. It allows running dependencyTree in multiple subprojects and appending their outputs to the same target file instead of overwriting.
**Solution**
- Add Arg.Append in the CLI parsing
- When --append is set, write using IO.write(..., append = true)
**Problem**
Running `sbt -error ~run` still prints [info] messages from the watcher
("Monitoring source files...", "Build triggered by...", etc). The watcher
creates its logger using only the watchLogLevel setting (default Info),
ignoring the global log level set via CLI flags like -error or -warn.
**Solution**
In Continuous.getCallbacks, take the more restrictive of the watchLogLevel
and the global log level from State when configuring the watcher appender.
Fixes#7355
- Replace `ivyModule` with Coursier's `dependencyResolution.moduleDescriptor` in the `evicted` task, removing a direct Ivy dependency from the eviction-checking path
- Gate Ivy-specific tasks (`makePom`, `makeMavenPomOfSbtPlugin`, `deliverTask`, `publisher`, `publishOrSkip`, `depMap`, `GlobalPlugin.extract`) behind `useIvy` so they error or return empty when `useIvy = false`
- Fix `.value` hoisting bug in `ivylessPublishTask` where `ivyModule.value` and `publisher.value` inside `match/case` fallback branches were macro-hoisted as task dependencies regardless of runtime path, breaking all ivyless publishes
- Add `ivylessPublishM2Task` so `publishM2` works with `useIvy = false` (publishes to `~/.m2` via `ivylessPublishMavenToFile`)
- Flip `useIvy` default from `true` to `false`
Summary
- Adds support for passing JVM arguments inline to `run`, `runMain`, `bgRun`, `bgRunMain`, and `fgRun`/`fgRunMain` using `--` as a delimiter
- Syntax: `run <jvmArgs> -- <appArgs>` (e.g., `run -Xmx2G -Dapp.mode=debug -- arg1 arg2`)
- Fully backward compatible — without `--`, all arguments are treated as app args as before
- When `fork` is `false`, a warning is logged that JVM arguments will be ignored
- **Remove `ivyModule` from `updateTask0`**: Replace `IvySbt#Module` with `moduleSettings` + `DependencyResolution.moduleDescriptor()`, eliminating the Ivy dependency in the update path.
- **Replace direct Ivy usage in `Load.scala` and `TemplateCommandUtil`**: Use Coursier's `DependencyResolution` API for plugin bootstrapping and template resolution instead of constructing `IvySbt` instances directly.
- **Break `lm-coursier`'s dependency on `lm-ivy`**: Remove `IvySbt#Module` pattern match from `CoursierDependencyResolution`, replace `IBiblioResolver` usage in `Resolvers` with reflection, and switch build dependencies from `lmIvy` to `lmCore`.

Fixes nondeterministic ordering in `ScopeFilter`-backed `.all(...)` aggregation.
`SettingKeyAll.all` and `TaskKeyAll.all` previously iterated a `Set[Scope]` using `toSeq`, which made returned values order-dependent on hash iteration. This PR keeps `.all(...)` deterministic and preserves explicit project ordering when a filter provides it (for example, `inProjects(c, a, b)`).
When a test fails with ClassNotFoundException/IllegalAccessError, sbt
suggests a set command to change classLoaderLayeringStrategy. If the
project name contains hyphens (e.g. bug-report), the suggested command
was syntactically invalid because it parses as subtraction in Scala.
Quote project IDs using Util.quoteIfNotScalaId so the suggested
commands are valid when copy-pasted.

- CompileDebugLogger wraps logger to prefix debug messages with [projectId]
- projectIdFromScope derives id from task scope (avoids HashWriter on ResolvedProject)
- Wire CompileDebugLogger into compileIncrementalTaskImpl and compileJavaTask
- Add CompileDebugLoggerSpec unit test and i408-debug-invalidation-prefix scripted test
sbt 2.x allows `dependsOn(...)` between subprojects with mismatched
Scala versions without any warning or error. This can lead to confusing
classpath issues at compile or runtime, especially now that Scala 3.8+
has dropped backward TASTy compatibility with 2.13.
Per review feedback, move the Scala version mismatch check from
compileTask to projectDependenciesTask, where PR #8681 already handles
Scala version mixing logic. This provides earlier detection and keeps
the validation co-located with cross-version resolution.

- ClientSubscriptionTest: assert default client receives build/logMessage when command runs.
- Scripted test server/client-subscription: run show name to exercise server client path.
Treat explicit plugin toggles as last-call-wins for the same plugin.
This avoids contradictory include/exclude states when disablePlugins(X) is followed by
enablePlugins(X) (and vice versa), aligning behavior with normal override expectations.
Apply the same semantics to ProjectMatrix and add regression coverage:
- unit tests in main/src/test/scala/ProjectSpec.scala
- scripted test in sbt-app/src/sbt-test/project/i1926-disable-enable-plugin
Fixes#4310
Per review, the OOM comes from the version parser - token(StringBasic)
on the right side of || has no examples constraint. Move
.examples(knownVersions*) from the inner number parser to wrap the
entire || expression, so both alternatives are bounded.
When Test / autoScalaLibrary := false, build the non-fork test classloader
without the ScalaInstance layer: use Flat strategy and project classpath
only (rawCP), so tests do not see sbt's scala-library and avoid
NoSuchMethodError / version mismatch (e.g. scala/scala build).
- ClassLoaders.testTask: read autoScalaLibrary; when false use Flat and
rawCP-only fullCP, and do not add si.libraryJars to exclude.
- Add scripted test tests/autoScalaLibrary-test-loader that runs test
with Test / autoScalaLibrary := false.
**Problem**
`testFull` can select an aggregate-only key before a directly defined root key.
In issue #8772 this causes root project tests to be skipped, so a failing root test can pass unexpectedly.
**Solution**
Prefer directly defined keys in `Act.select`, and only fall back to aggregate-only candidates when no direct key exists.
Add scripted regression test `tests/i8772-root-project-testfull` and keep `project/extra-projects-key-aggregate` behavior intact.
Change the behavior when a cached task's output type contains
java.io.File: instead of silently skipping the cache, throw a
compile-time error with a message recommending xsbti.VirtualFileRef,
xsbti.HashedVirtualFileRef, or xsbti.VirtualFile, and linking to the
caching documentation.
Internal sbt tasks that return File types are wrapped with
Def.uncached to opt out of caching.

* [2.x] fix: Reject java.io.File as cached task output type
Use @transient on File-returning keys in Keys.scala instead of
wrapping tasks with Def.uncached in Defaults.scala. This ensures
build users who rewire these tasks also get caching skipped
automatically.
- Add @transient to 19 File-returning taskKey definitions in Keys.scala
- Revert Def.uncached wrappers from Defaults.scala
- Error at compile time when File is used as cached task output type
- Update error message to recommend @transient and link to docs

When `semanticdbEnabled := true` is set on Scala 2.x projects, the
`doc` task fails because `${CSR_CACHE}` placeholders in scalacOptions
(specifically the `-Xplugin:` path for the semanticdb compiler plugin)
are not resolved before being passed to Scaladoc.
This fix resolves virtual file references (containing $) in
scalacOptions before passing them to the Scaladoc bridge, matching
what zinc's MixedAnalyzingCompiler already does for compilation
(see sbt/zinc#1545).

Allow settings to delegate when the user specifies an explicit scope
(config or task axis), so that e.g. Compile/console/fork resolves
when console/fork is defined in a delegated scope. Tasks continue to
not delegate (getDirect only) so non-existent scopes like Compile/update
still fail as in 2.0.0.
**Problem**
Adopting Scala 3.8 on sbt 2.x has created confusing errors with scala-library mismatch,
popping up as undefined summon.
**Solution**
Removing the Provided scope seems to work.
- CacheUrlConversion: normalize paths for comparison (forward slashes)
and strip leading slash on Windows file URIs so cache matching works.
- Apply scalafmt to touched files.
- Add CacheUrlConversion in lm-coursier internal to convert cache file
paths back to original repository URLs (single place for logic).
- CoursierDependencyResolution delegates to CacheUrlConversion.
- DependencyLockManager.createFromUpdateReport now accepts optional
cacheDir; when an artifact has a file URL it either converts via
cache dir (Coursier layout) or fails with a clear message.
- dependencyLock task passes csrCacheDirectory so lock file gets
portable HTTPS URLs instead of machine-specific cache paths.
Expectation 1: Lock file contains original Maven Central (or repo) URLs.
Expectation 2: If conversion is not possible, lock creation fails.
**Problem**
When the user runs testOnly with an explicit suite name (e.g. testOnly com.example.MySuite),
ScalaTest suites annotated with @DoNotDiscover were not run because sbt always passed
explicitlySpecified=false to the test framework.
**Solution**
In Tests.processOptions, when the user has specified test filters (orderedFilters.nonEmpty),
mark the filtered tests as explicitlySpecified=true with SuiteSelector so frameworks
can run @DoNotDiscover suites when explicitly requested.
- this should also work for global plugins once they are fixed in sbt 2.x
- add `missingOk` support in classifier resolution to enable failure-tolerant artifact retrieval
**Problem**
When `last` output includes ANSI escape sequences (e.g. colored `[error]` lines), `lastGrep <pattern>` was matching against the raw string. The pattern could fail to match because it was compared to text like `\u001B[31merror\u001B[0m` instead of `error`, or matching was inconsistent.
**Solution**
- Strip ANSI from each line before running the regex, using `EscHelpers.stripColorsAndMoves` from `sbt.internal.util`.
- **`Output.lastGrep`** (keys and file overloads): lines from the last run are stripped, then the pattern is applied to the stripped text; matching and printed lines are based on visible text.
- **`Output.grep`**: each line is stripped before `showMatches(pattern)` so the pattern is applied only to visible content.
**Problem**
Forked console currently pulls in full Zinc, which includes JLine.
**Solution**
This implements a lighter-weight, full Java ForkConsoleMain,
which no longer depends on JLine.
Build-level references (ThisBuild, BuildRef) should not participate
in aggregation. Only project-level references should aggregate.
Previously, when querying `ThisBuild/version`, the aggregation logic
would resolve ThisBuild to a BuildRef, then convert it to the root
project's ProjectRef, causing it to incorrectly use the root project's
aggregate definitions.
The fix uses pattern matching to distinguish BuildReference from other
reference types, returning None (no aggregation) for build-level scopes.
Fixessbt/sbt#5349
- BuildServerProtocol: for Result.Inc(cause), return StatusCode.Error for any
non-InterruptedException (was throwing for non-CompileFailed, causing JSON-RPC

- BuildServerTest: add test 'buildTarget/compile - returns StatusCode.Error
when compilation fails' (introduce compile error, compile via BSP, assert
statusCode == Error)
**Problem**
Setting `Global / autoStartServer := false` in global.sbt triggers a
spurious lintUnused warning, even though the setting is correctly used
by sbt's server startup logic.
**Solution**
Add `autoStartServer` to the `excludeLintKeys` set in LintUnused.scala,
similar to other server-related settings like `serverConnectionType` and
`serverIdleTimeout`. This prevents the warning while maintaining the
functionality of the setting.
**Problem**
1. forked console is missing user code from the classpath.
2. forked console still blocks the server.
**Solution**
1. This includes proper products and classpaths to the console.
2. This also implements client-side run for console.
Commit 92b0564dc (fix for #8632) changed `csrSameVersions` so that Scala 2.13+ only aligned `scala-library` and `scala3-library`. This removed `scala-compiler` and `scala-reflect` from version
unification, so transitive dependencies pulling in an older `scala-compiler` (e.g. 2.13.15 via `refined_2.13`) were no longer evicted to match `scalaVersion` (e.g. 2.13.18).
**Problem**
The configuration name translation in logging was incorrect. When a
configuration like MultiJvm (id="MultiJvm", name="multi-jvm") was
displayed, it showed "Multi-jvm" instead of "MultiJvm" because the
display logic was guessing the identifier by capitalizing the ivy
config name.
**Solution**
This fix:
- Adds configNameToIdent reverse mapping in ConfigIndex to look up
the correct Configuration.id from the ivy config name
- Adds toConfigIdent method in KeyIndex trait for display lookup
- Updates Scope.display to accept a config name lookup function
- Updates showLoadingKey and showContextKey to use the index lookup

Implements cooperative idle server cleanup for `sbtn` (issue #8610). When a client disconnects from an sbt server, that server notifies all
other registered servers to shut down if they've been idle long enough and have no connected clients. This prevents accumulation of idle
background JVMs across projects.
fixes#8610
When an AutoPlugin adds a project at the build root via extraProjects,
avoid creating a second root from the build definition so both do not
share the same target directory. Treat extraProjects root as 'root
already defined' and exclude the build-defined root from initialProjects
when both would be at the same base.
- Add ivylessPublishMavenToFile and ivylessPublishMavenToUrl for Maven layout
- Handle MavenCache and MavenRepo in ivylessPublishTask (file + HTTP)
- Add credentialFor for realm+host credential matching per Publishing docs
- Consume HTTP response body on success to avoid connection leak
- Add scripted tests: ivyless-publish-maven, ivyless-publish-maven-http
When using the aggregated key parser, a key is now valid if it exists in `data` for that scope **or** it's an aggregate key and every key it aggregates to exists in `data`. So `(root, scripted)` is accepted when the root aggregates a project that defines `scripted`, and running `scripted` at root runs it on that project as before.
Implements ivyless publish task as part of #7639 (drop Ivy dependency).
Fixes#8639.
- Add ivylessPublish for URLRepository: HTTP PUT with optional Basic auth,
same layout as ivyless publishLocal (artifacts + ivy.xml + checksums).
- Add ivylessPublishToFile for FileRepository: write to local path for
testing without HTTP server.
- Add ivylessPublishTask: when useIvy is false, use ivyless path for
URLRepository or FileRepository; otherwise use Ivy.
- Wire publish in Defaults to LibraryManagement.ivylessPublishTask
(tagged Publish, Network).
- Add scripted test dependency-management/ivyless-publish using
Resolver.file to verify ivyless publish produces identical layout.
Credentials supported via allCredentials (Basic auth for PUT).
When a project depended on another project that was built with a different Scala binary version (e.g. 2.12 vs 2.13), compilation could fail with "not found: value X" because resolution was asking for the wrong artifact.
This change updates how we build the `ModuleID` for inter-project dependencies in `projectDependenciesTask`: we now request the dependency’s Scala binary version (e.g. `bar_2.12`) instead of the current project’s, so the resolver can find the right artifact. We keep existing behavior for `Disabled` and `Constant` cross-version, and add a small safeguard in the default case when the dependency’s Scala version differs from the current project’s.
**Consuming BOMs**
- You can declare a BOM with `.pomOnly()` and versionless deps with `"*"`:
- `libraryDependencies += ("com.fasterxml.jackson" % "jackson-bom" % "2.21.0").pomOnly()`
- `libraryDependencies += "com.fasterxml.jackson.core" % "jackson-core" % "*"`
- BOMs are passed to Coursier via `Resolve.addBom()`; version `"*"` is resolved from the BOM.
**makePom**
- POM-only dependencies are emitted under `<dependencyManagement><dependencies>...</dependencies></dependencyManagement>` with `<type>pom</type>` and `<scope>import</scope>`.
- Dependencies with version `"*"` are emitted without a `<version>` element so Maven uses the BOM-managed version.
**Ivy / publishLocal emulation**
- When publishing to Ivy (e.g. `publishLocal`), BOM-resolved versions (deps that had `"*"`) are written into the published `ivy.xml` as forced dependencies (`force="true"`), so consumers that depend on this module get those versions.
**Problem**
1. Write a scripted test that runs sbt in that test.
2. sbt writes `sbt.version` under `project/build.properties`, which acts as a test filter.
3. The test setup is implicitly altered.
**Solution**
Before writing `build.properties`, sbt checks whether the base directory is inside a scripted test directory (path contains `sbt-test`). If so, it skips writing so the test setup is not altered.
Add a rootProject convenience macro that expands to a Project with base "."
and the enclosing val name as id. Allows writing `val root = rootProject`
instead of `val root = (project in file("."))` for a stable root project id.
Resolving ThisProject to ProjectRef(uri, p.id) created a self-reference
in the aggregate (and dependency) list. BuildUtil.checkCycles runs
topological sort on this relation and throws Cyclic when it sees the
self-loop.
Treat ThisProject as no-op: resolve to Vector.empty so the build loads
without error. aggregate(ThisProject) / dependsOn(ThisProject) is
effectively a no-op (self is already included).
Fixes#3616 - Scope's resolveProjectBuild and resolveProjectRef
mishandle ThisProject.
Previously, using ThisProject in aggregate() or dependsOn() would
cause a runtime error: 'Cannot resolve ThisProject w/o the current
project'.
This change adds proper handling for ThisProject in Load.scala:
- In checkAll: Skip validation for ThisProject (refers to self)
- In resolveProjects: Resolve ThisProject to ProjectRef(uri, p.id)
Problem
When a user defines an alias with a name that matches an existing task or setting key (e.g., `alias c = compile` when a custom task `c` exists), the alias silently wins and shadows the task.
Solution
Detect conflicts at alias creation time and fail with an error message:
```
Alias 'c' conflicts with a task or setting key of the same name. Use a different alias name to avoid ambiguity.
```
**Problem**
When multiple clients connect to the same sbt server, they all share the same "current project" state. When one client switches projects with `project X`, all other clients see that change.
**Solution**
Store per-channel project cursors in State attributes. Each client maintains its own cursor that tracks which project it has selected.
In PR #8621, I added a new `keepTempDirectory` parameter to `ScriptedRun.run()` and `invoke()` methods. To suppress MiMa warnings, I added `mimaBinaryIssueFilters` for:
- `DirectMissingMethodProblem("sbt.ScriptedRun.run")`
- `DirectMissingMethodProblem("sbt.ScriptedRun.invoke")`
- `DirectMissingMethodProblem` for various internal `RunV1`, `RunV2`, `RunInParallelV1`, `RunInParallelV2` classes
However, this broke binary compatibility, which prevents sbt 1.x from calling sbt 2.x for cross-building (building sbt 2.x plugins using sbt 1.x).
Fixes#8631
**Changes:**
- Add `useIvy` setting key (defaults to `true`)
- Add `ivylessPublishLocalImpl` helper that publishes without Ivy
- Modify `publishLocal` to use ivyless publisher when `useIvy := false`
- Generate ivy.xml via `lmcoursier.IvyXml`
- Generate MD5/SHA-1 checksums for all files
- Add scripted test `dependency-management/ivyless-publish-local`
## Problem
We enforce same-version policy for scala-reflect in Scala 2.13.
However due to sandwich dependency, the graph can bump
scala-library to 3.8.1, which is missing scala-reflect counterpart.
## Solution
Drop the same-version policy.
**Problem**
When running scripted tests to debug sbt plugins, the temporary directories (`/private/var/folder/...`) are automatically deleted after tests complete. This makes it difficult to inspect the test state for debugging purposes, requiring workarounds like adding `$ pause` commands and manually copying directories.
**Solution**
Added a new `scriptedKeepTempDirectory` setting that allows users to preserve temporary directories after scripted tests complete. When enabled, the temporary directory path is logged so users can inspect it.
Usage:
```scala
scriptedKeepTempDirectory := true
```
Problem
When using `addCompilerPlugin((dependency) % Test)`, the compiler plugin was incorrectly added to BOTH `test:scalacOptions` AND `compile:scalacOptions`, instead of only `test:scalacOptions`.
Solution
Throw when the dependency is scoped, since we do not support this use case.
**Problem**
When `autoAPIMappings := true` is set on a Scala 3 project, running `sbt doc` emits warnings:
```
[warn] bad option '-doc-external-doc:/modules/java.base#https://docs.oracle.com/...
```
This happens because Scala 3's scaladoc doesn't recognize Scala 2's `-doc-external-doc` option.
Fixes#6652
**Solution**
- Added `Opts.doc.externalAPIScala3` that generates the Scala 3 format: `-external-mappings:regex::[scaladoc3|javadoc]::url`
- Modified `Defaults.scala` to use the appropriate method based on Scala version
- Added heuristics to detect javadoc vs scaladoc based on file/URL patterns
**What it does**
When you run `dependencyLock`, sbt generates a `deps.lock` file that captures your resolved dependencies. This file can be checked into version control to ensure reproducible builds across different machines and CI environments.
**New tasks**
- **`dependencyLock`** - Generates the lock file from the current resolution
- **`dependencyLockCheck`** - Validates the lock file is up-to-date (fails build if stale)
**How it works**
The lock file stores a hash of your declared dependencies and resolvers. When dependencies change, the hash changes, and `dependencyLockCheck` will fail until you regenerate the lock file.
If no lock file exists, `dependencyLockCheck` passes silently - this allows gradual adoption.
Add support for `"3-latest.candidate"` to automatically resolve to the latest Scala 3 RC from Maven Central.
```scala
scalaVersion := "3-latest.candidate"

When running commands like 'Test/definedTests' on multi-project builds,
the output was showing raw Vector(...) format instead of nicely formatted
per-item output.
Before:
[info] svc / Test / definedTests
[info] Vector(Test FooSpec : ..., Test BarSpec : ..., ...)
After:
[info] svc / Test / definedTests
[info] * Test FooSpec : ...
[info] * Test BarSpec : ...
The fix extends printSettings to check if values are Seq types in
the multi-project case and format each item on its own line with
a '* ' prefix, matching the single-project behavior.
**Problem**
Currently the shell delegates request tasks even when a non-existent
task like Compile / update is requested.
**Solution**
This removes the delegation, if the input key is scoped, so it will fail.
We will, however, continue to delegate on the subproject axis,
since it's useful to use Global or ThisBuild scoping.
Fixes#8356
**Problem**
When `sbtn` sends a command while another long-running task (like `console`) is already executing, the client silently blocks with no indication that the command is waiting in a queue.
**Solution**
When a new command arrives via the network channel and another command is currently running, the server now sends an `ExecStatusEvent` notification with status `"Queued"` to the client. The client displays a message like:
```
[info] waiting for: console
```
**Problem**
When binary compatibility eviction errors occur, users cannot run
`dependencyTree` to debug the dependency conflict because it fails
with the same eviction error.
**Solution**
Set `evictionErrorLevel` and `assumedEvictionErrorLevel` to `Level.Warn`
for the `dependencyTreeIgnoreMissingUpdate` task, allowing the dependency
tree to be displayed even when eviction errors are present.
Fixes#7255
When using fork := true, sbt spawns child processes that may become
stale if cancelled. Previously, these processes were not cleaned up
when running the exit command.
This fix adds RunningProcesses.killAll() to the shutdown hook so that
all tracked forked processes are terminated when sbt exits.
Fixes#7468
Fixes#7481
When sbt is started by a remote client (BSP or thin client via --server flag),
always start the server regardless of autoStartServer setting. The autoStartServer
setting is meant for automatic server startup, not for blocking explicit server
start requests.
Fixes#7489
When using nested task scopes like otherTask / testTask, the
inputFileChanges macro was returning the wrong scope. It checked
if the scope already had a task axis and returned it as-is, but
this meant it would use otherTask's scope instead of testTask's.
The fix always sets the task axis to the key being queried,
ensuring fileInputs settings are found at the correct scope.
When watchTriggers is explicitly set (non-empty), use only watchTriggers
instead of combining them with fileInputs. This allows users to control
what triggers the watch by setting watchTriggers.
Fixes#7130
When sbt.version in build.properties has trailing whitespace,
sbt incorrectly reports a version mismatch even after reboot.
This fix trims the property value in all places where sbt.version
is read from build.properties:
- Main.scala (version mismatch warning)
- MainLoop.scala (clean command version detection)
- ScriptedTests.scala (test compatibility check)
Fixes#8103
**Problem**
When a val definition in build.sbt changes and the user runs `reload`, sbt crashes with `NoClassDefFoundError: $Wrap<hash>$`.
```
java.lang.NoClassDefFoundError: $Wrape8743d4f36$
at $Wrap0b8ea34d40$.$anonfun$1(build.sbt:1)
```
The workaround was to delete `project/target` directory.
**Solution**
The root cause was that imports were not included in the hash calculation when evaluating build.sbt expressions. When a val definition changes:
1. Its `$Wrap` module gets a new hash
2. Settings that reference the val get new imports pointing to the new module
3. But if the setting expression didn't change, its hash was the same
4. The old cached class was loaded with bytecode referencing the old module
Fix: Include imports in the hash calculation in `Eval.evalCommon`. Also re-enable `cleanEvalClasses` in `Load.scala` which was disabled pending this fix.
Filters out empty versions during parser construction to prevent RuntimeException when creating token parsers. Includes comprehensive test coverage for edge cases.
