问题
I got this ANT task:
<javac verbose="on"
srcdir="${src.dir}"
destdir="${build.dir}/${context.path}/classes"
debug="${compile.debug}"
debuglevel="${javac.debuglevel}"
optimize="${compile.optimize}"
deprecation="${javac.deprecation}"
failonerror="true">
<compilerarg value="-Aeclipselink.persistencexml=${web.dir}/META-INF" compiler="javac1.6" />
<compilerarg line=" -processor org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor" />
<compilerarg line=" -proc:only" compiler="javac1.6" />
<classpath refid="compile.classpath"/>
</javac>
When I ran the above task, I got this error:
[javac] error: java.lang.IllegalArgumentException
[javac] An annotation processor threw an uncaught exception.

I've traced the error to this line <compilerarg value="-Aeclipselink.persistencexml=${web.dir}/META-INF" compiler="javac1.6" />. It looks like the parser does not like the compiler's argument value -Aeclipselink.persistencexml. The above error is reproducible with both JDK 1.6.0.24 and JDK 1.6.0.25. The error is caused by org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor.process.
I'm using EclipseLink version 2.2.0.v20110202-r8913 that comes bundled with Glassfish 3.1. I have also tried compile the above task with the standalone EclipseLink libraries version 2.2.0.v20110202-r8913 and got the same error.
Is there a workaround for the above error?
回答1:
To solve the error java.net.URISyntaxException: Illegal character in opaque part at index 2, I had to move my META-INF to the same directory where ANT's build.xml reside. This is only a workaround.
I have logged a bug at https://bugs.eclipse.org/bugs/show_bug.cgi?id=345808. The EclipseLink folks have fixed this bug for EclipseLink version 2.3.0 release.
