Hi,
I get an unsupported operation exception when trying to include some files
to the project archive. It seems that underlying an
Collections.singletonList is used and hence no adding is allowed after
creation of the collection.
eg:
task('archive_jar').zipFileSet(dir: file('etc/schemas')) {
include('*.xsd')
}
here is the stack trace.

I could fix the issue by changing the default 'resourceCollections' that is
assigned in the JavaPlugin on line 112 in current trunk.
from:
jar.conventionMapping(GUtil.map("resourceCollections",
GroovyJavaHelper.createConventionClosure(Collections.singletonList(new
FileSet(javaConvention.getClassesDir())))));
to:
ArrayList list = new ArrayList();
list.add(new FileSet(javaConvention.getClassesDir()));
jar.conventionMapping(GUtil.map("resourceCollections",
GroovyJavaHelper.createConventionClosure(list)));
