If it matters, I've also run this with a plain Ant build.xml file and a
"simple" execution of the XJCFacade class on the command line, all with the
same results. Note that I can generate this error with XJCFacade without even
specifying any schemas to process. This error happens while plugins are being
loaded, before it starts to process schemas.
I've also replaced my local build of JAXBXMLElementWrapperPlugin with the
public artifact of the same plugin, still with the same result.
If it matters, here is the complete Ant build.xml that I'm using, with one
small elision. Note that I'm pulling the jars out of my Gradle cache, but that
doesn't rely on Gradle itself.
