**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**
sbt currently does not support JDK 25 Main class. JDK 25 supports:
1. non-public main method
2. doesn't need Array[String] arg
3. doesn't have to be a static method
**Solution**
This updates Zinc, which supports new Main class detection.
In addition, this implements in-process run emulation support.
**Problem**
For sbt 1.x, the user is forced to pick between having a stable ID for the root project,
or having the automatic aggregation of all subprojects.
The problem becomes more pronounced for large build that frequent add/remove subprojects.
**Solution**
This implements `.autoAggregate` method on `Project`, which is implemented as
`this.aggregate(LocalAggregate)`.
At the loading time, we can automatically expand `LocalAggregate` to a list of subproject references,
after we discover all subprojects.
The `autoAggregate` will use the base directory of the subproject to pick the parent-child
relationship. For example, a root project would aggregate all subprojects,
but `bar` might aggregate only `bar/bar1` and `bar/bar2`.
**Problem**
Forked tests apparently incorrectly returns success if an exception is thrown
on JDK 17 and up, due to exception failing to persist.
**Solution**
This adds custom codec for Throwable to workaround this issue.
**Problem**
managedScalaInstance := false fails Java-only tests because
the test runner is based on a Scala Runner and sbt 2.x
currently derives the ScalaInstance only from update.
**Solution**
For the purpose of Java-only testing, create a dummy Scala Instance.
Previously, sbt would fail to load build.sbt files when they included
annotated definitions because the parser would not correctly recognize
those definitions as such. In sbt 1.x, this used to be fine, because
there was little use for annotations in build.sbt.
Starting with sbt 2, whether caching should be enabled for a task key
can be controlled via annotations on the task key definition. Because
these can appear in build.sbt, support for annotations in build.sbt
becomes more important.
This patch enhances parsing of build.sbt by keeping the parsed trees
around so that the AST can be used to determine whether a given line
represents a setting or a definition, rather than relying on string
matching.
**Problem**
While sbt-dependency-graph is useful, not just for the basic ASCII graph,
but for DOT file generation etc, it adds a large number of settings and
tasks for combination of formats and actions to the point that
we actually disable most of them by default.
**Solution*
I've had an idea for a while that dependencyTree can be implemented
as a inputTask that accepts its own subcommands and options,
and this implements that.
For example, to open the browser that hosts a DOT file, now you can write
dependencyTree dot --browse
**Problem**
test task is typed to unit.
To distinguish test from any other tasks, we want to actually type this to something.
**Solution**
Forward TestResult to the test task.
Previously, sbt would crash when attempting to load a build where
projects had minus signs (`-`) in their name.
For instance, when trying to load a project defined like this:
lazy val `my-project` = project
After compilation, this definition looks somewhat like this
val my$minusproject$lzy1 = ...
sbt was attempting to retrieve the original definition (without the $lzy
suffix) by taking the mangled name up to the first `$`. Unfortunately,
this approach does not work when the name includes special characters
like a minus sign, because these will be prefixed with `$` as well. In
the current example, sbt would then try to find the member named `my`,
fail, and crash.
This patch fixes the issue by using the "underlying" name, which is the
name without the additional information.
