org.apache.maven.内部错误异常：内部错误：java.lang.IllegalArgument异常：畸形的\uxxxx编码为MAC

Question

我在MAC上运行，在Java项目上运行mvn安装，我遇到了这个错误。我在网上查了一整天，但大多数答案都是关于/和的，但是我没有本地更改，我的团队可以很好地建立回购协议，我以前也可以成功地建立回购协议。我还看到有人也面临同样的问题，但在他们修复了JAVA版本之后，它对他们来说很好。https://stackoverflow.com/questions/68003423/java-lang-illegalargumentexception-malformed-uxxxx-encoding-while-mvn-install?newreg=96abc52a5b8e46d9a72155ef37f33c81.我已经尝试了所有的方法，但它们都不起作用：我已经尝试重新安装JAVA、MAVEN，还更新了JAVA/MAVEN版本。我记得我在将JAVA/MAVEN切换到旧版本之前和切换到旧版本时遇到了类似的问题，它工作得很好，但这次不再工作了。有人能帮忙吗？我真的很感激。我试过MAVEN 3.8、MAVEN 3.5、MAVEN 3.3，他们都有这个问题。我在使用JAVA11时遇到了一些问题，然后我切换到JAVA8并卸载了JAVA11。

以下是完整的堆栈跟踪：

您可以在/中删除存储库中下载的包。m2/repository/**下载maven依赖项的文件夹（为了安全起见，请备份）。

在IDE（sts或eclipse）中，尝试进行maven构建（干净安装）。

希望你的问题解决了。
