ubuntu17.10 idea 导入项目，maven依赖导入失败问题

参照网上的教程，maven reimport，设置import maven projects automatically，maven clean，maven package，maven install等之后，在External Libaries处还是没有把jar包引进来的问题。

然后查看maven控制台，发现是文件加载之类的问题，遂觉得是权限设置问题，然后查看maven repository的权限，发现为755权限（本文只说明本人解决问题的过程，如果有不懂的知识点，请自行google之），猜想会不会是我的repository没有这个jar，然后从网上dowload idea没有写入的权限呢，然后修改权限为777,再执行maven reimport，发现还是不能。

发现idea是要把maven依赖相关的内容写在.iml或者是.idea里面，于是猜测是不是当前用户没有对这两个文件写入的权限，于是查询，真没有！跟之前的repository一样是755权限，于是修改，再参照上面那个用户的回答，关闭idea，到目录底下删除.idea 和 \*.iml，然后设置项目目录和其所有子目录及文件的权限为777,重新启动idea导入项目，maven 依赖倒入成功！
