On some configurations (like a Kotlin project), the cleanup of the
generated-soruces/annotations directory returns an error:

I didn't catch this earlier since I don't use Kotlin and on a normal project,
this should not be an issue since the javac documentation mentions that the
directory, and any necessary subdirectories, will be created if they do not
already exist.
But on a somewhat modified project that compiles kotlin source code, this
triggers an issue on plexus-compiler where the generated-soruces directory does
not exist.
This might be related to issue MCOMPILER-538, where it claims that generated
source root is not required for javac, but additional confirmation is required.
The fix will be to create the generated sources directory to preserve the
current behavior.
