maven-shade-plugin 不会替换原来的 jar

Question

奇怪的是，我的 maven-shade-plugin 没有用阴影 jar 替换原始 jar。有谁知道可能是什么原因吗？

这是我在 pom.xml 中的插件

Shaded 插件默认将原始文件保存为

-original.jar

，如果您想用新生成的（阴影）替换原始文件，请将此行放在您的配置插件部分：

<configuration>
    ...

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

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

看起来配置标签应该位于层次结构中的执行标签内，如下所示。请重新组织执行和执行标签，并在其下包含您的配置，如下所示。
