对应的文件D:\tools\maven\repostory\com\alibaba\cloud\spring-cloud-alibaba-dependencies\2.1.2.RELEASE\spring-cloud-alibaba-dependencies-2.1.2.RELEASE.pom是：

 

解决思路

这里乍一看pom依赖文件下载下来的居然是一个html文件（正常的应该是一个xml格式的文件），那很有可能是idea远程仓库拉去依赖的时候出问题了。。

找到本地仓库对应的pom文件，将后缀改为.html，浏览器打开看一下远程仓库给我们的数据页面：

 

 

乍一看是出现503错误（503是一种HTTP状态码。英文名503 Service Unavailable与404（404 Not Found)是同属一种网页状态出错码。前者是服务器不可访问时给客户端的一种状态，后者是访问了服务器不存在的资源。） 

既然问题找到了，那就检查一下本地项目的pom.xml中maven仓库的配置是否正确：

将pom.xml文件中配置的maven远程仓库地址注释掉（我本地maven/config/setting.xml已经配置过响应地址），然后重新reload一下maven项目

在mvn clean一下发现不报错了：

再查看一下对应大的pom依赖，发现正常下载下来了
