Fixes https://github.com/sbt/sbt/issues/6558
Problem
-------
sbt uses SecurityManager feature of JDK to trap `sys.exit` call during
`run`-like tasks, since we emulate `run` and `console` as function calls.
JDK 17 deprecated SecurityManager and it's printing warnings.
Solution
--------
About 10 years go, `exit` was a convenient way of quitting both Scala
REPL and sbt shell. Scala 2.11 broke this by removing the `Predef.exit`.
We still need to worry about `run` potentially calling `sys.exit`
but that can be handled using fork feature.
In the long-run, it probably is better to be JDK 17 compatible.
Currently crossSbtVersions is incorrectly generating a warning that it
is an unused setting (see https://github.com/sbt/sbt/pull/5153). This
PR fixes this by adding it to the list of excluded lint keys.
Fixes#6571.
Ref #6592
When there's an issue like timeout, currently it throws a
ClassCastException because I made some assumption about the underlying
error. This removes the unnecessary casting.
This fixes the closed channel exception generated when running
sbt -timings help. This bug was introduced in sbt 1.4 where a wrapper
was created (Terminal.scala) around the terminal. This meant that the
shutdown hook which had been used previously was no longer working.
This has been fixed by avoiding the use of the JVM shutdown hook and
instead manually running the thunk at a place in the code where
the programme is still able to respond.
The request of the form buildTarget/* often take a sequence of build
targets as parameter. So far if there is an error on a single build
target, the entire request fails.
This is not the best because the client wants the result of the other
build targets anyway:
For example:
- workspace/buildTargets: if one build target has an invalid Scala
version we still want to import the other ones
- buildTarget/scalacOptions: if a dependency cannot be resolved we still
want to import the build targets that do not depend on it
- buildTarget/scalaMainClasses: if buildTarget does not compile we still
want the main classes of the other targets
...
The change is to respond to BSP requests with the successful
build targets and to ignore the failed ones.
This is implemented the same in Bloop since before BSP in sbt.
In https://github.com/build-server-protocol/build-server-protocol/issues/204,
I made a proposal to also add the failed build targets in the response.
Since build.sbt is compiled/evaluated in `sbt.compiler.Eval`,
this commit introduces a `BuildServerEvalReporter` to redirect
the compiler errors to the BSP clients.
A new `finalReport` method is added in the new `EvalReporter` base class
to reset the old diagnostics.
- Restore old type of `bspWorkspace` key for backwards compat.
Instead, introduce `bspFullWorkspace` that includes the
SBT targets
- Log a warning if the client requests, e.g. `scalaMainClasses`
for a SBT target
- Refactor the code that creates the SBT build targets so it
doesn't depend on `sbtFullWorkspace`.
- Add a setting `bspSbtEnabled` to let the user opt-opt of
SBT target export (e.g. to compensate for a client that does
not yet support them)
What is the problem?
When using remote caching, the resource files are not tracked so if they
have changed, pullRemoteCache will deliver both the old resource file
as well as the changed one.
This is a problem, because it's not the behaviour that our users will
expect and it's not in keeping with the contract of this feature.
Why is this happening?
Zinc, sbt's incremental compiler, keeps track of changes that have
been made. It keeps this in what is called the Analysis file.
However, resource files are not tracked in the Analysis file, so
remote caching is not invalidating the unchanged resource file in
place of the latest version.
What is the solution?
PullRemoteCache deletes all of the resources files. After this,
copyResources is called by PackageBin, which puts the latest
version of the resources back.
If the user runs foo/runMain in a project with multiple main classes,
sbt will still warn the user about their being multiple main classes
even though this is a pointless warning since the user either is running
runMain which requires a main class. The run task is also excluded since
by default it prompts the user with a main class selector. The previous
logic for doing this filtering was bad because it only looked at the
first command in a sequence and couldn't handle the foo/runMain case
since it was looking for an exact match with `run` or `runMain`. This
commit relaxes those restrictions to look at all of the strings in the
command as well as splitting the string to check if the last part of the
key ends in run or runMain. This logic could theoretically be incorrect
if the user wrote an input task that was expecting run or runMain as
user input but even in that case the only consequence would be that they
wouldn't see the multiple main class warning which generally isn't all
the helpful unless you are packaging a jar that expects there to be only
one main class. It seems unlikely that that the user would be running a
custom input task that is both packaging a jar and expecting run or
runMain as input strings.
