So i see a lot of metamodel classes got generated but during this process i got this:
[javac] An annotation processor threw an uncaught exception.
[javac] Consult the following stack trace for details.

Details on how to recreate :

Hi,
this is nearly impossible because its not an Entity which makes the problem here. Its a package. I have no idea how to unit test that. Perhaps you can try creating
a simple package with JAXB generated classes in it and try to reproduce:
1) create a very simple XSD file
2) run the JAXB compiler via ANT (then you should have some classes in myweirdpackage)
<target name="JAXBCompiling" description="Compile main source tree java files">
<taskdef name="xjc" classname="com.sun.tools.xjc.XJC2Task" classpathref="toolingclasspath"/>
<xjc schema="my.xsd" destdir="${src.dir}" package="domain.myweirdpackage"/>
</target>
3) put at least one Entity in domain package (parent of myweirdpackage)
4) run the MetaModel compiling step
