Intellij Spring Boot-Start kann Hauptklasse nicht finden ... Wirft eine com.intellij.rt.execution.application.AppMain.main

Question

Ich bin nicht in der Lage, das Spring-Boot-Projekt mit der IDE ausführen, weil es beschwert, nicht zu finden die Hauptklasse. Die Hauptklasse wird im Setup der Ausführungskonfiguration korrekt als Feld eingegeben, daher weiß ich nicht genau, was dieses Problem verursachen würde. Diese

ist, was intellij läuft:

Answer 1

Meine beste Vermutung ist, dass der tomcat starter ist im Lieferumfang enthalten und Intellij IDEA does not resolve it properly. Es gibt verschiedene Problemumgehungen zu dem Problem.
