如何生成effective-pom

effective-pom是什么?我们知道任何一个项目的pom都至少继承了maven内置的超级pom,有些项目中的用户还会配置自己的继承层次,也就是说,但从当前的pom是无法全面了解项目信息的,你必须同时查看所有父pom. maven有一个effective pom的概念,它表示一个合并整个继承机构所有信息的POM,假如项目A继承自项目B,而项目B又继承自超级POM,那么A的Effectiv POM 就包含了所有A,B一级超级POM的配置,有了Effectve POM,用户就能一次得到完成的POM信息.

Maven用户使用命令行获取effective-pom,在termal中进入当前pom所在的文件夹(cd 命令)

$ mvn help:effective-pom

Effective POMs, after inheritance, interpolation, and profiles are applied:
