Es ist ungefähr so einfach wie möglich, Java Kotlin aufrufen. Nicht sicher, wie ich es sonst noch vereinfachen könnte. Dies ist ein version Problem?
Während ich Netbeans verwende, wird Graplel ausschließlich vom CLI ausgeführt. Ich kann sogar die NB-Dateien löschen, sollte sich das als nützlich erweisen.
Wahrscheinlich drucke ich gerade nicht auf die Konsole correctly.
