运行 Maven Shade 插件时，出现以下错误。我该如何调试呢？

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.0:shade (make-shade) on project csprocessor-client: Error creating shaded jar: Unexpected end of ZLIB input stream -> [Help 1]

事实证明，使用 m2eclipse 插件，您实际上可以在执行 maven 插件时对其进行调试。为此，您需要选择要单步执行的代码，您可以通过在 Maven 运行配置中设置调试输出选项来实现。您还需要设置Resolve Workspace artifacts选项。

在此处输入图像描述

使用这两个选项，我可以单击错误中列出的文件位置（在本例中为 ZipFile.java:411），设置断点，然后使用Debug As > Maven Build在调试模式下运行 Maven 构建。一旦断点被​​命中，我就可以知道哪个文件导致了错误，并使用JAR 命令重新打包它。即使有问题的 JAR 文件可以使用 GUI 存档工具打开，一旦使用 JAR 命令重新打包，我也可以成功运行 Maven Shade plgin。

仅供参考，如果这是由下载期间损坏的 JAR 引起的，强制重新下载的快速方法是mvn dependency:purge-local-repository在着色项目中运行。这将从本地 Maven 存储库中删除项目的所有依赖项（直接和传递）并重新下载它们。
