Ich habe NullPointerException mit dem Maven-Compiler-Plugin: 3.1. Ich habe ähnliche Fragen zu SOF gestellt, vergeblich aber versucht.Maven-Compiler-Plugin: 3.1: Kompilieren fehlgeschlagen. NullPointerException

Der Befehl, den ich lief: mvn compile

3.1 ist ziemlich alt. Verwenden Sie die neueste Version 3.5.1 und versuchen Sie, [mcve] des Problems zu veröffentlichen. – Tunaki

Verwenden Sie nicht Maven 3.0.3, die wirklich fehlerhaft ist. Verwenden Sie eine aktuellere Version wie 3.3.9 ... – khmarbaise

Ich habe dieses Problem gelöst - es war ein Problem mit der Dateiberechtigungen.
