This PR includes the values of the `description` and `homepage`
settings into the `ivy.xml` files generated by the `makeIvyXml`
task. It restores the behaviour of sbt 1.2.8 and if `useCoursier`
is set to `false`.
Two things are changed in this PR:
* `IvyXml.content` now adds the `homepage` attribute to the
`description` element if `project.info.homePage` is not empty.
* `CoursierInputsTasks.coursierProject0` now fills the previous
empty `CProject.info` field with the description and homepage.
Closes: #5234
Ref #4211Fixes#4395Fixes#4600
This is a reimplementation of `--addPluginSbtFile`. #4211 implemented the command to load extra `*.sbt` files as part of the global plugin subproject. That had the unwanted side effects of not working when `.sbt/1.0/plugins` directory does not exist. This changes the strategy to load the `*.sbt` files as part of the meta build.

It is still possible for progress threads to leak so shut them down if
there are no active tasks. The report0 method will start up a new thread
if a task is added.
In some circumstances, sbt would generate a number of task progress
threads that could run concurrently. The issue was that the TaskProgress
could be shared by multiple EvaluateTaskConfigs if a dynamic task was
used. This was problematic because when a dynamic task completed, it
might call afterAllCompleted which would stop the progress thread. There
also was a race condition because multiple threads calling initial could
theoretically have created a new progress thread which would cause a
resource leak.
To fix this, we modify the shared task progress so that the `stop()`
method is a no-op. This should prevent dynamic tasks from stopping the
progress thread. We also defer the creation of the task thread until
there is at least one active task. This prevents a thread from being
created in the shell.
The motivation for this change was that I found that sometimes there was
a leaked progress thread that would make the shell not really work for
me because the progress thread would overwrite the shell prompt. This
change fixes that behavior and I was able to validate with jstack that
there was consistently either one or zero task progress threads at a
time (zero in the shell, one when tasks were actually running).
When running sbt -Dtask.timings=true, the task timings get printed to
the console which can overwrite the shell prompt. When we use a logger,
the timing lines are correctly separated from the prompt lines.
I noticed that when entering the console, I'd often be left with a
supershell line at the bottom of the screen that would eventually get
interlaced with my console commands. This can be eliminated by clearing
the supershell progress before evaluating the task if it is one of the
skip tasks.

There's been report of intermittent "Could not create directory" error related to "classes.bak." retronym identified that all configurations are using the same directory, and that might be the cause of race condition.
This addresses the issue by assigning a unique directory for each configuration.
The way clean was implemented, it was running `clean`, `ivyModule` and
`streams` concurrently. This was problematic because clean could blow
away files needed by `ivyModule` and `streams`. To fix this, move the
cleanCachedResolutionCache into a separate task and run that before the
normal clean.
Should fix https://github.com/sbt/sbt/issues/5067.
The completions were generating page numbers that didn't make sense if
there were a small number of scripted tests. For example, suppose that
there were only two tests defined, it would generate *1of3 *2of3 and
*3of3 completions even though there weren't even three tests.
These classloaders which are created if sbt is launched with a legacy
launcher (or one that doesn't follow the current classloading hierarchy
convention), were implemented in scala, but that meant that they were
not parallel capable. I fix that by moving the implementations to java.
I also move the static method that creates a MetaBuildLoader into the
java class.
A number of users were reporting issues with deadlocking when using
1.3.2: https://github.com/sbt/sbt/issues/5116. This seems to be because
most of the sbt created classloaders were not actually parallel capable.
In order for a classloader to be registered as a parallel capable, ALL
of the parent classes except for object in the class hierarchy must be
registered as a parallel capable:
https://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html#registerAsParallelCapable--.
If a classloader is not registered as parallel capable, then a global
lock will be used internally for classloading and this can lead to deadlock.
It is impossible to register a scala 2 classloader as parallel capable
so I ported all of the classloaders to java.
This commit updates the java-serialization scripted test. Prior to the
port, the new version of the test would more or less always deadlock.
After this change, I haven't been able to reproduce a deadlock.
This had no significant performance impact when I reran

It is necessary to close the run classloader in order to reuse the
dependency layer in the next run. If the loader needs to survive past
the main method, as is the case with `run` and `runMain`, then the
runWithLoader api should be used instead.
This mostly restores the behavior of classloader closing to 1.3.0 for
the tasks that use ScalaRun except for `run` and `runMain`. But unlike
1.3.0, if the classloader is closed it can still spawn a zombie
classloader.
Fixes#5124.
I don't think that dummy tasks really make sense for task progress
because they are evaluated outside of the normal task evaluation. This
came up because I was seeing streams-manager in supershell which didn't
seem useful.
I noticed some flickering in super shell progress lines and realized
that it was because there were multiple progress threads running
concurrently. This is problematic because each thread has a completely
different state so if each thread has an active task, the display will
flicker between the two tasks. I think this is caused primarily by
dynamic tasks. At least the example where I was seeing it was caused by
a dynamic task.
If a project had a meta-meta build (project/project), the build sources
in the project directory were ignored. This was because the projectGlobs
method did not correctly handle recursion. It inadvertently
discarded the accumulator globs and only returned the most recently
generated globs. This commit fixes that and adds a regression test to
the nio/reload scripted test.
