问题：
1.新建项目后会提示一个这样的错
maven-compiler-plugin:3.1:compile(1 errors)
maven-compiler-plugin:3.1:testCompile(1 errors)
2.关掉后看pom.xml
3.plugin标签也报错，无法解析
鼠标放红叉上提示
错误：
CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact

解决：
排查eclipse配置maven的地方，和配置的仓库都没问题
再排查settings.xml，可以尝试更换镜像的配置，但我不是这个问题（可以换成下面这个，是我成功后的）
<mirrors>
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>
因为错误是说解析不了plugin，我猜想是上次更新时强制关闭eclipse导致某些包没更新好，然后导致版本问题之类的总之无法解析出来报错，就重新换了一个仓库，就成功了
我认为应该是你自己的maven仓库里\org\apache\maven目录下的一些关于plugin的包受损了 ，也可以尝试只更换别人好的maven文件夹
新建maven项目出错 pom.xml报错
