调用maven包命令时创建的“dependency-reduced-pom.xml”文件是什么？

问题描述

我正在从泉源

I'm following maven tutorial from springsource here, and after 1) adding joda-time dependency , and 2) calling mvn package commmand, we get the below file dependency-reduced-pom.xml.

My question is, what is the purpose of creating this file besides pom.xml file?

解决方案

If you set to true the flag createDependencyReducedPom (by default is true), the dependencies that have been included into the uber JAR will be removed from the <dependencies> section of the generated POM.

The reduced POM will be named dependency-reduced-pom.xml and is stored into the same directory as the shaded artifact.

Unless you also specify dependencyReducedPomLocation, the plugin will create a temporary file named dependency-reduced-pom.xml in the project basedir.
