上为遇到的错误的代码和图片

解决办法为勾掉Contact all update sites during install to find required software。

随后在配置的时候又出现了 Target is not a supported Maven Home这个错误，如图↓

原因是我下载maven包错误，如图↓
PS：两个内的settings.xml 是一样的，如果之前修改过，只需要拿之前修改的那个用就行了

注：https://blog.youkuaiyun.com/qjyong/article/details/9098213 博主在修改setting.xml的时候在m2文件夹前加了个点，像这样d:/.m2.然经过测试Windows下文件夹名字前无法加点,但我在c盘却见到了这种命名方式的文件夹，暂时没弄明白，有大佬知道望指点一下。
