maven - 是否自动使用dependency-reduced-pom.xml而不是pom.xml？

Question

由Maven shade plugin 创建的dependency-reduced-pom.xml是否自动在依赖uberjar的项目中使用(而不是普通的pom.xml)？

在阅读了一些与dependency-reduced-pom.xml相关的问题之后，还没有找到答案，就问这个问题:

Maven shade plugin adding dependency-reduced-pom.xml to base directory

What is the purpose of dependency-reduced-pom.xml generated by the shade plugin?

What is `dependency-reduced-pom.xml` file which created when calling maven package command?

Answer 1

dependency-reduced-pom.xml在构建时生成到项目的${basedir}中。该文件是一个临时文件，仅用于包装到有色 jar 中。引用 createDependencyReducedPom 属性的文档:

Flag whether to generate a simplified POM for the shaded artifact. If set to true, 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.

为了清楚起见，在运行 maven-shade-plugin之后:

您的初始POM将保持不变；

将在根文件夹(this is considered an open issue with this plugin)中生成一个可以完全忽略的名为dependency-reduced-pom.xml的临时文件；

带阴影的 Artifact 将在META-INF目录中包含未更改的初始POM，而不包含简化的POM(这不是很重要，但最好提一下-存在一个已自动关闭的问题:MSHADE-36)；

将要部署的POM是简化的POM；

默认情况下，阴影 Artifact 将成为项目的主要 Artifact 。
