so i got everything working except this error in script compilation:
Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option
i fixed this before using compilerOptions.append("-jvm-target", "1.8") or something similar but that seems to have no effect anymore
