Description

JavacCompiler.java (actually in plexus-compiler-javac, but I cannot find the source project for this anywhere) has

List sourceLocations = config.getSourceLocations();
if ( sourceLocations != null && !sourceLocations.isEmpty() && ( sourceFiles.length == 0 ) )

{ args.add( "-sourcepath" ); args.add( getPathString( sourceLocations ) ); }

The sourceFiles.length == 0 clause should be deleted. The problem is that javac really does need to have -sourcepath even when you are passing an explicit list of *.java files; it is necessary for 269-compliant annotation processors:

Following is a patch which

1. Fixes diagnostics to print compiler arguments even for unforked mode. (javac is still run with a command line when unforked, so there is no reason to omit this valuable diagnostic info.)

2. Hacks maven-compiler-plugin to work around the bug in plexus-compiler-javac and pass -sourcepath. Obviously a fix to p-c-j would be preferable.

When applied to m-c-p 2.0.2 it allows the test case to build.

269 support in general would require this to be fixed.

Even if this were fixed, the expected output from the test case would be invisible unless MCOMPILER-66 were fixed too.

MCOMPILER-97 has to be worked around in test case.

Workaround seems to be:

<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerArguments>
<sourcepath>${project.basedir}/src/main/java</sourcepath>
</compilerArguments>
</configuration>
</plugin>
</plugins>
</build>

the compiler plugin's trunk still references the 1.6 version of the javac compiler plugin.

Note that for annotation processors which load non-Java resources from the sourcepath, the above fix will not suffice since it only includes Java sources. Untested workaround:

<compilerArguments>
<sourcepath>${project.basedir}/src/main/java:${project.basedir}/src/main/resources</sourcepath>
</compilerArguments>

Unfortunately just adding src/main/resources to -sourcepath does not suffice, due to a bug in javac:

(link may take a few days to work)

I've opened the MCOMPILER-122 for the resources usecase. closing this one as the generic -sourcepath case is fixed.
