**Problems**
When running forked tests, sbt uses `Runtime.getRuntime().availableProcessors()` to determine the thread pool size, ignoring `concurrentRestrictions`. This is inconsistent with non-forked parallel tests.
**Expectations**
Users should be able to control the number of parallel test threads in forked mode, similar to how `concurrentRestrictions` works for non-forked tests.
**Notes**
Added a new setting `testForkedParallelism` that allows explicit control:
```scala
testForkedParallelism := Some(2) // Use 2 threads
testForkedParallelism := None // Use availableProcessors() (default)
```
Eviction warnings and errors were not reported for Test dependencies because
`EvictionError` only checked the Compile configuration.
This fix runs the eviction check for both Compile and Test configurations
separately, with distinct error messages:
- Compile: `found version conflict(s) in library dependencies`
- Test: `found version conflict(s) in Test dependencies`
When project loading fails in batch mode, sbt was showing an interactive
prompt asking the user to choose between retry, quit, last, or ignore.
However, in batch mode there is no interactive terminal, causing the
process to hang waiting for input that will never come.
This fix checks if we're in batch mode (Prompt.Batch) and automatically
exits with failure (equivalent to 'q' quit option) without prompting the
user. This prevents infinite retry loops on persistent errors and allows
batch mode scripts to fail fast, which is appropriate for CI/CD environments.
The interactive behavior remains unchanged for non-batch mode.
**Problem**
There's a disconnect between what is perceived to be the current
Scala version, and what sbt uses internally, and thus what it
chooses to be the default scalaVersion.
**Solution**
This displays a warning if scalaVersion setting is missing.

**Problem**
sbt 2.x uses crossTarget by default, but it contains Scala version
even when crossPaths is false.
**Solution**
This replaces it with the letter "u" for unspecified.
Preserve original direct dependencies (plugins) and merge with transitive dependencies
Original dependencies may include plugins that are NOT transitive dependencies of sbt
**Problem**
Compiler bridge resolution calls out to Coursier,
and it shows up on the profiler.
**Solution**
This uses sbt 2.x caching to cache the prebuilt compiler bridge binaries
to avoid calling Coursier from second time onwards.
**Problem**
During the milestone releases of Scala, e.g. Scala 2.13.0-M1,
scalaBinaryVersion by design points to 2.13.0-M1,
and also the source directory uses scala-2.13.0-M1,
but in most cases we actually want to pretend compatibility
and use scala-2.13 directory.
**Solution**
This introduces a new setting called scalaEarlyVersion,
which is the scalaBinaryVersion of the release version of milestones.
We have been calling this "partial version", but that broke
down for Scala 3, which adopted semantic versioning.
**Problem**
On IntelliJ the users are getting the hint to upgrade to -Xsource:3
style, however the supported syntax do not parse.
**Solution**
This adds -Xsource:3 to the parser. The metabuild compilation uses
-Xsource:3 since sbt 1.6.0.
**Problem**
Protobuf reading shows up as one of the bottlenecks during no-op compilation.
**Solution**
This adds a local, in-memory cache of Zinc Analysis using the timestamp
and the file size of the persisted protobuf file.
**Problem**
sha256 is currently a bottleneck for no-op compilation.
**Solution**
This adds a local, in-memory cache of sha256 hashes of binary files
using their timestamp and file size.
The size of the digest cache can be configured using localDigestCacheByteSize,
which is set to 1MB by default.
**Problem**
dependency-tree currently doesn't include Provided configuration,
because technically it isn't part of the Compile configuration,
however, Provided does become part of the Compile classpath during compilation.
**Solution**
This changes the implementation to use the internal configuration,
e.g. CompileInternal, which includes the auxilary configurations.
There's a tradeoff here since it means that we lose the tree view of
the platonic Compile configuration.
**Problem**
Scala 3.8 REPL won't work since they've split the repl artifact into another JAR.
**Solution**
This works around it by creating a yet-another sandbox configuration ScalaReplTool
(similar to ScalaTool and ScalaDocTool) and a separate scalaInstance for
console task, so when Zinc is invoked we'll be able to conjure the right array of JARs.
