java - Maven Shadow 插件打包项目后，目标中未找到任何 Shadowed jar

Question

运行mvn package:shade shade时，日志中的条目显示:用 XYZ-shaded.jar 替换 XYZ.jar 但在我的目标目录中，我找不到阴影 jar

这是我关于 Maven 阴影的 pom

经过尝试，这个 pom 帮助了我

Answer 1

检查一下输出的 jar 文件是否是阴影文件吗？

Shade 插件可能替换此处的原始文件，这意味着用着色版本覆盖它。

如果您希望最后获得两个 jar 文件(着色和未着色)，您可能需要将 shadedArtifactAttached 属性设置为 true:

Defines whether the shaded artifact should be attached as classifier to the original artifact. If false, the shaded jar will be the main artifact of the project

参见Maven Shade Mojo Documentation.
