我运行了这个演示(使用 PowerShell)。一切都很好,直到我运行该行:
mvn exec:java -Dexec.mainClass="com.blobs.quickstart.App"-Dexec.cleanupDaemonThreads=false
然后我得到了以下异常:

最佳答案
即使使用了该插件,我也收到了该错误消息。我通过更改双引号修复了它(我也在使用 Powershell):
mvn exec:java -D"exec.mainClass=my.main.Clazz" [other args with same quote pattern]
关于java - 未知生命周期阶段 ".mainClass=com.blobs.quickstart.App",我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/68794430/
