maven-shade-plugin 不会替换原来的 jar

问题描述

奇怪的是，我的 maven-shade-plugin 没有用带阴影的 jar 替换原来的 jar.有谁知道可能是什么原因?

这是我在 pom.xml 中的插件

解决方案

Shaded plugin 默认保存原文件为-original.jar，如果你想用新生成的(shaded)替换原文件，把这行放在你的配置插件部分:

...<outputFile>${output.directory}\${project.artifactId}-${project.version}.jar</outputFile>...</配置>

用你的阴影插件 outputDirectory 替换 output.directory.

It is weird that, my maven-shade-plugin doesn't replacing the original jar with the shaded jar. Does anyone know what could be the reason ?

Here's my plugin in pom.xml

解决方案

Shaded plugin by default save original file as -original.jar, if you want to replace original file with the new generated (shaded), put this line in your configuration plugin section:

<configuration>
    ...

    <outputFile>${output.directory}\${project.artifactId}-${project.version}.jar</outputFile>
    ...
</configuration>

Replace output.directory with your shade plugin outputDirectory.
