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
- Update scripted tests to use @transient approach

**Problem**
`scalaOrganization` was ignored during compiler bridge resolution because `ZincLmUtil.getDefaultBridgeModule` hard-coded `ScalaArtifacts.Organization` (`org.scala-lang`).
**Solution**
Add a `scalaOrganization` parameter to `ZincLmUtil` methods, and passing `scalaOrganization` value to those methods.

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**
After PR #8730 (commit 921efce), inline comments in .jvmopts and .sbtopts files cause errors.
For example, `--add-opens=java.base/java.util=ALL-UNNAMED # comment` results in:
Error: Could not find or load main class #
The # and everything after it is now parsed as separate arguments instead of being stripped as a comment.
**Solution**
Update the sed command in outputConfigFileTokens() to strip inline comments (everything from # to end of line) before parsing tokens.
The new s/\s*\#.*// pattern matches optional whitespace + # + rest of line and removes it.

Catch parse errors when reading cached values and return Left(None)
so the task is re-run instead of failing with IncompleteParseException.
Fixes plugins/dotty-sandwich scripted test flake.
**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**
The sbt launcher script used naive word splitting when parsing `.sbtopts` and `.jvmopts`, so arguments with spaces were split incorrectly. For example, `-J--add-modules jdk.incubator.concurrent` in `.sbtopts` and `-Dtest.key="value with spaces"` in `.jvmopts` were not passed to the JVM as intended.
**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**
`sbt --version` in sbt 2.x project directories was delegated to the native client, which could try to start/connect to a server instead of printing version info.
**Solution**
Skip native-client delegation when `--version` is requested, and add runner-script tests for sbt 1.x and 2.x project variants.
**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.
**Problem**
ScalaTest's `AsyncFunSuite` invokes the test framework's event handler **asynchronously**. sbt's `TestFramework` was collecting events in a **`ListBuffer`**, which is not thread-safe. With multiple suites (e.g. `IgnoreBugTestA` and `IgnoreBugTestB`), concurrent `handle()` calls could corrupt the buffer, so events from the second suite were lost or merged incorrectly and the summary showed wrong suite/test counts.
**Solution**
Replaced the event buffer in `sbt.TestFramework`'s `EventHandler` with a **thread-safe** collection: **`CopyOnWriteArrayList`** (from `java.util.concurrent`). Event handling now uses:
- `CopyOnWriteArrayList[Event]` for `results`
- `results.add(e)` in the handler
- `results.asScala.toList` when building `TestEvent` / `SuiteResult` (via `scala.jdk.CollectionConverters._`)
This preserves ordering and ensures all suites' events are reported correctly when using async styles like `AsyncFunSuite` with `test`/`ignore`.
When usePipelining is enabled and compilation has errors, CancellationException
was being thrown and showing confusing stack traces to users. This fix catches
the exception in ConcurrentRestrictions.take() and converts it to Incomplete,
which is properly handled by the task execution framework without showing stack
traces.
- Added CancellationException import
- Wrapped jservice.take().get() in try-catch
- Convert CancellationException to Incomplete to prevent stack traces
- Added scripted test to verify the fix
Fixes#7973
When a dependency declares a version range (e.g. Ivy [1.3.1,2.3] or comma-separated "1.3.1,2.3" as used by Coursier), and the resolver picks a version inside that range, sbt was still reporting an eviction warning. The chosen version satisfies the range, so it should not be reported as an eviction.
Example (from #6244): oauth2-oidc-sdk and nimbus-jose-jwt both depend on net.minidev:json-smart with range [1.3.1,2.3]. Resolution selects 2.3, which is within the range. Before this fix, sbt reported an eviction for json-smart even though 2.3 satisfies [1.3.1,2.3].
When in an sbt 2.x project directory, the script used to delegate to sbtn
before checking --script-version, so 'sbt --script-version' ran sbtn and
failed. Now we print the script version and exit before the native client
branch.
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
**Problem**
Apparently sbt can fail when it doesn't have rm,
which can happen "when building relocatable RPM's and building an OS image in a chroot."
**Solution**
It was suggested that we require coreutils.
- 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.
