effective-pom是什么?我們知道任何一個項目的pom都至少繼承了maven內置的超級pom,有些項目中的用戶還會配置自己的繼承層次,也就是說,但從當前的pom是無法全面了解項目信息的,你必須同時查看所有父pom. maven有一個effective pom的概念,它表示一個合並整個繼承機構所有信息的POM,假如項目A繼承自項目B,而項目B又繼承自超級POM,那么A的Effectiv POM 就包含了所有A,B一級超級POM的配置,有了Effectve POM,用戶就能一次得到完成的POM信息.
Maven用戶使用命令行獲取effective-pom,在termal中進入當前pom所在的文件夾(cd 命令)
$ mvn help:effective-pom
Effective POMs, after inheritance, interpolation, and profiles are applied:
<?xml version="1.0" encoding="GBK"?>
