Automatic modules open all their packages and so the --add-opens here 
with be a no-op.

As regards the IllegalAccessException then I don't know the types 
involved here so know if 
org.gradle.groovy.scripts.internal.GradleResolveVisitor is a sub-type of 
org.codehaus.groovy.control.ClassNodeResolver or not. It's possible this 
is nothing to do with modules but running with 
-Dsun.reflect.debugModuleAccessChecks=true might reveal something useful.
