最近看hadoop，maven下载依赖包各种问题，无奈之下我只有频繁重新创建项目，不免有重名。

以上为背景。

根据错误提示，我琢磨着，应该把这个VFS里面的内容清理一下，因为毕竟我已经在文件中将project删除了。但是我不知道VFS是啥

遂上stackoverflow找方法，遇到一哥们，问题如下：

When I would like to re-create a maven project with a name had been but have been deleted already, I receive the following error message:

Failed to create maven project: ‘…/pom.xml’ already exists in VFS

下面靠谱回答：

See Cleaning System Cache page.

1. Open any project in IntelliJ IDEA
2. Select “File > Invalidate Caches / Restart …”
3. Click on “Invalidate and Restart”

WARNING:

1. Cleaning out the system caches, keep in mind that:
2. It results in clearing the local history.
3. To avoid losing data, check in the changes to your version control system before invalidating caches. Causes a complete rebuild of all the projects ever run in the current version of IntelliJ IDEA.

大体的意思是让我们清除缓存。还提醒我们在清缓存之前注意版本控制问题。

删掉这个残缺不全的项目，然后 Invalidate and Restart 重新建立。OK
