问题和解决方案

idea的maven一开始是没有setting.xml的，你要去maven的目录里面拷一份setting.xml到你的仓库中。idea的maven在安装路径的plugins文件夹下，即X:\xxx\JetBrains\IntelliJ IDEA 2016.3.2\plugins\plugins\maven\lib\maven3\conf\setting.xml拷贝到你的用户文件夹下的.m2文件夹下，为了之后能够快速的下载依赖包，我们要加一个官方库的镜像，因为maven的官方仓库在国外，太慢了。 
在你的.m2文件夹下的setting.xml中添加如下代码：

      alimaven
      central
      aliyun maven
      http://maven.aliyun.com/nexus/content/repositories/central/

这个是阿里的库，所以很快。做完之后我们回到idea，点击next，然后填写项目名，然后finish。 
接下来idea开始创建项目，这里你要把maven自动导入打开。

总结

不止是IDEA自带的Maven没有settings.xml文件，我在使用自己的Maven时，也是出现这种错误，一开始在选择settings.xml文件的时候，都是去找Maven目录下的settings.xml

依然报上面的错误，我的自带Maven仓库是在E:/maven下的。settings.xml是需要放在仓库目录中

注意：maven的位置跟仓库是两个位置
