我正在进行mvn干净安装，然后是java-jar。然后我使用了注释中@ajozwk提到的命令，但我还有一个问题，persistence.xml文件位于src/main/而不是src/main/resources下。现在我的问题解决了

我创建了一个项目，并从“创意-所有作品”开始运行。如何运行应用程序？试试mvn exec:java-Dexec.mainClass=“edu.deakin.sarms.service.sarmcontrol”。我做到了，mvn清洁安装。测试了java-jar。您的命令很有用，但我有另一个问题，persistence.xml文件不在src/main/下，而在src/main/resources下。现在我的问题解决了！
