编译maven 项目时候报错提示下面信息：

Since Maven 3.8.1 http repositories are blocked.

Possible solutions:
- Check that Maven settings.xml does not contain http repositories
- Check that Maven pom files do not contain http repository http://XXXXXX:8081/repository/maven-public/
- Add a mirror(s) for http://XXXXXX:8081/repository/maven-public/ that allows http url in the Maven settings.xml
- Downgrade Maven to version 3.8.1 or earlier in settings

使用私服作为mirrors，如果你的maven是3.8.1+的版本，我用的是3.9.6版本.

会提示：Since Maven 3.8.1 http repositories are blocked。

自从3.8.1版本开始，处于安全考虑，maven禁用了http的镜像仓库，企业安装的私服通常都是http的地址，所以报这个错误。

修改方案

在pom.xml

	<mirror>
	  <id>maven-default-http-blocker</id>
	  <mirrorOf>dummy</mirrorOf>
	  <name>Dummy mirror to override default blocking mirror that blocks http</name>
	  <url>http://0.0.0.0/</url>
	  <blocked>false</blocked>
	</mirror>
