使用idea对maven项目打包时，报 invalid LOC header (bad signature)异常处理

打包，报错：

根据提示在项目目录下使用 mvn -X package 执行，则将详细堆栈信息打印出来：

看到最后一个DEBUG信息，找到对应目录" H:\apache-maven-3.3.9\repository\org\apache\parquet\parquet-jackson\1.7.0\",发现以.sha1-in-progress结尾的文件，说明jar没有正常下载，删除重新执行，同时观察该目录即可：

 

 

 再执行到这里时，提示如下：

 

 

说明正常下载了，对应目录：

 

 

 已经正常。

（多说一句，如果发现进度条走了一半不走了，可以停掉删除重新来；另外，国内用aliyun的maven库要快很多）

 

总结：出现invalid LOC header (bad signature)时，按提示带上-X执行mvn找到，.sha1-in-progress删除，重新执行即可。
