java.lang.IllegalArgumentException：mvn 安装时格式错误的 \\uxxxx 编码

Question

在我的项目中运行 mvn install 时，我遇到了这个错误。虽然很多答案和资源都指出了 / vs \ 中的错误，但我想提一下，我没有进行任何本地更改，而且这个 repo 对我团队中的其他人来说效果很好。它以前对我也很好用。

使用 JDK 1.8.0_291 在 Mac Os 10.15.7 上运行

请找到完整的堆栈跟踪：

我已经尝试过以下方法：

1. 在我的 mac 上重新安装了 java
2. 重新安装maven
3. 多次尝试使缓存无效并重新启动 IntelliJ。

对我来说，它也是一个损坏的依赖项。

我不想完成调试器的设置过程，因此决定在我的 ~/.m2 目录中查找包含 \u0000 的文件，方法是运行：

 grep -rnw ~/.m2 -e '\u0000'

之后你会得到损坏的文件，删除这些文件然后构建maven。

请注意，如果您将其配置为与默认设置不同，则必须指定您的存储库文件夹。阅读您的 ~/.m2/settings.xml 并改用 localRepository 中的值。例如：

 <settings>
  <localRepository>/else/where</localRepository>

利用：

 grep -rnw /else/where -e '\u0000'

如果您想要删除所有这些文件，请将文件名通过管道传递给 xargs rm ：

 grep -lrnw /else/where -e '\u0000' | xargs rm
