multiple errors like "bad path element "... ": no such file or directory when building Apache Kafka

[edoardocomar]

Describe the bug

Using VSCode with Scala(Metals) extension on the code of Apache Kafka (mixed Java/Scala built with Gradle).

Metals doctor shows lots of compilation status errors due to errors like this (from the metals log):

024.03.22 16:25:04 WARN  Unexpected javac output: warning: [path] bad path element "../kafka/.bloop/core-test/build/classes-empty-core-test": no such file or directory
warning: [path] bad path element ".../kafka/storage/api/src/test/resources": no such file or directory
error: warnings found and -Werror specified
1 error
2 warnings.
2024.03.22 16:25:04 WARN  javac exited with exit code 1
2024.03.22 16:25:04 INFO  time: compiled core-test in 29s

If the directories are created manually, then the status goes green.
As there are many such errors, it takes a long time to manually 'fix' the project

Expected behavior

Can the missing directories be auto-created if they do not exist ?

Thanks for reporting! This looks like something to fix inside Bloop. We should probably not invoke the Java compiler with directories that do not exists
