JAVAlang.IllegalArgumentException:安装mvn时格式错误\uxxx编码

Question

在我的项目中运行mvn安装时，我最终遇到了这个错误。虽然许多答案和参考资料指出了/与\之间的错误，但我想指出的是，我没有本地更改，此回购协议对我团队中的其他人很有效。它以前对我也很管用。

在Mac Os 10.15.7和JDK 1.8.0291上运行

请查找完整的堆栈跟踪：

[ERROR] 

我已经尝试了以下方法：

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

Answer 1

要查找哪个文件格式错误（因为不必删除整个Maven存储库），您可以这样调试它：

1. 在java中的相关行中添加断点。util。属性（详见错误堆栈跟踪），然后在调试模式下运行任何Maven操作

Answer 2

在我的例子中，问题是在第三方库中，不正确的字符以某种方式保存到resolver-status.properties文件（错误行的示例：maven-metadata-nexus-releases.xml.lastUpda\u0000\u0000\......），位于下~/. m2/仓库/路径到库。刚刚删除了带有库的文件夹，并重新构建了项目。

Answer 3

对我来说，这也是一个被破坏的依赖关系
我不想经历设置调试器的过程，因此决定在我的~/中查找包含\u0000的文件。m2通过运行以下命令创建目录：

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