在家编译一个Apache的开源项目，在编译时遇到错误如下：

　　当时编译的是开源的Carbondata项目，使用maven3.3.9，jdk是1.8。于是到网上各种搜索和查询看到各种答案，但是都没有能解决问题。其中有个提示说有可能是jar包损坏导致打开时出错。于是把所有的maven库的jar全删掉重新编译，OK编译成功。（也可以写代码检查哪个jar包坏了）

但是jar包为什么会损坏呢？ 我回顾了下编译过程，原来在一开始编译时经常下载jar包很慢，在下载的过程中直接中断重新，可能是这个原因导致的。

编译好后开始运行代码又报如下错误

　　又是各种搜索，有的说要下载正确的winutils.exe,有的说要用命令winutils.exe 给目录赋权限，有的说装了xxx软件冲突。。。。各种都做了还是同样的错误。最后重启一把（重启机器）好了

泪奔。。。。。。。
