      Description

      I am using Groovy with JSR-223 and I need to override the default Groovy class loader so I can provide a custom CompilationUnit with an additional PrimaryClassNodeOperation in the SEMANTIC_ANALYSIS phase.

      I don't know too much about Groovy internals, but as GroovyScriptEngineImpl's loader field is private and never gets reassigned, the only way I found for making it work is using reflection:

      private void overrideDefaultGroovyClassLoader(final ScriptEngine engine) throws Exception {
        final Field classLoader = engine.getClass().getDeclaredField("loader");
        classLoader.setAccessible(true);
        classLoader.set(engine, new CustomGroovyClassLoader());
      }
      

      If there is not a better way for doing this today, maybe GroovyScriptEngineImpl should provide a setter or a post construct-like callback method for allowing overriding such field.
