**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.
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
Fixes#8762

**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.
