在我的项目中(继承 BTW,所以它的某些方面仍然未知),在 Eclipse/m2e 下,我右键单击pom.xml>1 Maven Build并得到一个对话框:

选择要运行的启动配置:

  • m2 myproj (1):
  • m2 myproj (2):
  • m2 myproj (3):
  • m2 myproj:

但是查看项目的Properties> Run/Debug Settings,根本没有启动配置。没有任何。

这意味着什么?

我应该选择上面列出的 4 种配置之一吗?如果是这样,是哪一个?为什么?

更新 1:有趣的是,当我右键单击pom.xml并选择Run As>Run Configurations...时,我看到定义了这些配置:

在此处输入图像描述

不过,我仍然不知道这意味着什么。我不记得曾经定义过它们。他们是怎么到那里的?

更新 2: 显然,这些启动配置是通过单击某些关闭/取消按钮或类似按钮无意中创建的。所以我删除了除一个之外的所有内容,然后运行它:

奇怪的。我知道pom.xml选择Run As>时有目标并且构建良好Maven Install
