**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
error instead of BspCompileResult with statusCode Error)
- 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
Fixes#5211

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"
```

* test: Refactor setup-java tests to use real directory structure
---------
Co-authored-by: mkdev11 <noreply@users.noreply.github.com>
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.
