**Problem**
1. The ivyless publish task had ivyModule.value and publisher.value calls
inside match/case fallback branches. sbt's macro hoists ALL .value calls
from ALL match branches as task dependencies regardless of runtime path,
causing failures when useIvy=false even for supported repo types.
2. publishM2 used publishOrSkip which errors when useIvy=false, but M2
targets MavenCache which the ivyless path already supports.
**Solution**
1. Remove hoisted .value calls from fallback branches in ivylessPublishTask.
Replace with direct sys.error calls since these branches handle truly
unsupported repo types.
2. Add ivylessPublishM2Task using Def.ifS that publishes to MavenCache
via ivylessPublishMavenToFile when useIvy=false.

**Problem**
The evicted task directly uses ivyModule.value to get a module descriptor.
This creates an unnecessary dependency on Ivy for eviction warnings.
**Solution**
Use dependencyResolution.value.moduleDescriptor() which works with both
Ivy and Coursier resolvers, removing the direct Ivy coupling from the
eviction checking path.

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
Fixes unresolved dependency path reporting for Coursier (`ResolveException.failedPaths`) and adds a stable scripted regression.
This PR addresses 5168 by reconstructing unresolved dependency caller chains from the Coursier resolution graph and attaching them to `ResolveException.failedPaths`. That allows unresolved warnings to show the full path from the missing module up to the root project.
It also adds and stabilizes `lm-coursier/unresolved-path` scripted coverage by:
- using a local test Maven repo fixture (no flaky remote test dependency)
- checking update stream output via an sbt task (`checkLog`) instead of shell `grep`
- asserting the unresolved path includes missing module, transitive caller, and root project
- **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 using the arguments file (`@argsfile`) mechanism for forked runs,
double quotes inside arguments were not escaped, causing the JVM's
argument file parser to strip them. For example, passing `{"a":1}` as
an argument would result in `{a:1}`.
Escape `"` as `\"` in `createArgumentsFile`, matching the existing
backslash escaping, so the JVM correctly round-trips quoted arguments.

**Problem**
AGENTS.md contains a spelling typo in a section heading and a broken link for the tech stack document.
**Solution**
- Replaced "Pull reuqest guideline" with "Pull request guideline"
- Fixed tech stack link target to contributing-docs/07_tech_stack.md
**Problem**
CONTRIBUTING.md contains a typo: "guideslins" in the issue reporting sentence.
**Solution**
Replace "guideslins" with "guidelines" in CONTRIBUTING.md.
Summary
- Fix `SbtParser.importsToLineRanges` to prepend `import` keyword when missing from Dotty's `Import` AST node source spans
- Add unit test for comma-separated import parsing
Replace the custom JLineCompletion fallback with JLine 3's built-in
CASE_INSENSITIVE option on the LineReader, which handles case-insensitive
matching natively. Revert JLineCompletion.scala to its original state.
Fixes#2251
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.
Fixes#5803
Avoid launching sbt just to render --version by reading sbt.version directly from project/build.properties in the shell script, batch script, and sbtw wrapper. Tighten launcher integration assertions to verify version output no longer depends on the sbtVersion command output.
**Problem**
Running sbt 2.x with JDK 8 produces a confusing "server was not
detected" error because the JDK version check only required JDK 8+
and only ran in the non-native-client path.
**Solution**
Move java_version detection before the native client decision and add
checkJava17ForSbt2 that requires JDK 17+ when sbt major version >= 2.
Fixes#8813
* [2.x] fix: Fail early when sbt 2.x is run with JDK < 17 (sbtw)
Move JDK version check before native client decision in sbtw and
require JDK 17+ when build.properties declares sbt 2.x.
* [2.x] fix: Fail early when sbt 2.x is run with JDK < 17 (sbt.bat)
Move checkjava before native client decision in sbt.bat and require
JDK 17+ when build.properties declares sbt 2.x.
* [2.x] test: Add minimumJdkVersion helper and unit tests for sbtw
Extract JDK version check logic into Runner.minimumJdkVersion for
testability. Add RunnerSpec with tests for sbt 1.x, 2.x, and 3.x
version detection.
* [2.x] test: Bump fake java to JDK 17 for integration tests
The fake java script used by launcher integration tests reported
JDK 8. Since sbt 2.x now requires JDK 17+, the citest2 (sbt 2.x)
integration tests would fail with the new JDK version check.
* Simulate JDK 9+ rt.jar handling in fake java script
Instead of silently ignoring --rt-ext-dir (which causes sbt.bat
to mkdir on an empty string), properly simulate JDK 9+ behavior
by creating a temp directory with java9-rt-ext- prefix and a
dummy rt.jar inside it.

* Fix#4979: apply -debug (and other level options) at startup so loading shows debug log
- Parse log level from configuration.arguments in StandardMain.initialState
- Pass initialLevel to GlobalLogging.initial so console appender uses it from first log
- Set Keys.logLevel and BasicKeys.explicitGlobalLogLevels in initial state when level option present
- Add initialLevel parameter to GlobalLogging.initial (default Level.Info) for backward compatibility
- Add InitialLogLevelSpec tests for logLevelFromArguments
- Add docs/fix-4979-manual-verification.md for manual reproduction
**Problem**
The color-detection logic in Terminal.scala is interleaved with side
effects (system property reads, environment checks) making it hard to
understand and impossible to unit test.
**Solution**
Extract a pure `isColorDefault` function that takes all inputs as
parameters and returns whether color should be enabled. The existing
`useColorDefault` delegates to it. Add unit tests covering all priority
levels and heuristic branches.
Fixes#6050
**Problem**
When the sbt server fails to start (e.g. wrong JDK version), the client
only shows "failed to connect to server" hiding the actual error. The
server stderr is redirected to /dev/null to prevent Linux pipe buffer
deadlocks (#8442), so diagnostic output is lost.
**Solution**
Redirect server stderr to a temp file instead of /dev/null. When the
server fails to start (portfile never appears), read and print the temp
file contents before throwing ServerFailedException. The temp file is
cleaned up eagerly on both success and failure paths.
Fixes#8812
- Add UpdateReportCache case class wrapping UpdateReportLite with stats/stamps
- Implement toCache/fromCache for conversion between UpdateReport and cache
- Add readFrom/writeTo for CacheStore persistence with backward compatibility
- Add fromLiteFull to JsonUtil for full reconstruction from lite format
- Update LibraryManagement to use new persistence API
- Add benchmark comparing full vs lite deserialization
- Add unit tests for persistence correctness
- Add scripted test for cache round-trip verification
**Problem**
Excluding artifacts using `.exclude(org, name)` requires you to
explicitly set scala version in `name`.
**Solution**
- Deprecating `.exclude(org, name)` in favor of new
`.exclude(OrganizationArtifactName)`
- Fixing `lmcoursier.FromSbt` ignores `excludeRule.crossVersion`
When using the arguments file (`@argsfile`) mechanism for forked runs,
double quotes inside arguments were not escaped, causing the JVM's
argument file parser to strip them. For example, passing `{"a":1}` as
an argument would result in `{a:1}`.

backslash escaping, so the JVM correctly round-trips quoted arguments.

- 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.

Closes#4399
- Add subscribeToAll to InitializeOption (protocol); default true for backward compatibility.
- CommandExchange: send broadcast notifyEvent/logMessage only to channels with subscribeToAll.
- TestServer: support subscribeToAll parameter for tests; AbstractServerTest: subscribeToAllForTest.
- ClientSubscriptionTest: assert default client receives build/logMessage when command runs.
- Scripted test server/client-subscription: run show name to exercise server client path.
**Problem**
1. It's difficult to find out when Process fails.
2. global.base setting isn't needed in sbt runner script.
**Solution**
1. Forward to stderr as it happens.
2. Remove global.base setting in the runner script.
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.
