Alexander Kriegisch updated MCOMPILER-566:
------------------------------------------
Description:
When analysing MCOMPILER-424, at some point I wanted to know what happens if I
set {{fork=true}} or {{forceJavacCompilerUse=true}}. The result was bad: No
matter if I compile with {{mvn -e -X}} or {{verbose=true}}, I only see a
{{CompilationFailureException: Compilation failure}}. There seems to be no way
to actually see the underlying root cause. I have to compile in process via
Plexus {{JavaxToolsCompiler}} to see the {{AnnotationTypeMismatchException}}

It is not helpful to know _that_ compilation failed, but not _why_.
Intermediate result: I added some debug statements into
{{org.codehaus.plexus.compiler.javac.JavacCompiler::compileOutOfProcess}}:
{code:java}
returnCode = CommandLineUtils.executeCommandLine(cli, out, out);
System.out.println("### plexus javac return code: " + returnCode);
System.out.println("### plexus javac output:\n" + out.getOutput());
messages = parseModernStream(returnCode, new BufferedReader(new
StringReader(out.getOutput())));
System.out.println("### plexus javac messages: " + messages);
{code}
The Maven console log when running with the latest Maven Compiler and latest
Plexus Compiler (sorry for interspersed German messages due to locale auto
detection):
{code:none}

As you can see, Plexus {{JavacCompiler}} gets all the output from _javac_, but
then somehow discards it while parsing it in
{{JavacCompiler::parseModernStream}}. I have not debugged into that part yet,
but it looks like a Plexus Compiler Javac bug. Do I need to create a separate
issue in that project, or are we dealing with the same players here?
BTW, this...
{code:none}
