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: Failure to find org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 in http://repository.jboss.org/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of jboss-public-repository-group has elapsed or updates are forced

原因是：本地设置的镜像仓库中没有对应的jar导致的

<mirrors>  
    <mirror>
         <id>jboss-public-repository-group</id>
         <mirrorOf>central</mirrorOf>
         <name>JBoss Public Repository Group</name>
         <url>http://repository.jboss.org/nexus/content/groups/public</url>
    </mirror>
  </mirrors>

解决方法：

1.找到maven库目录，进入：~\.m2\repository\org\apache\maven\plugins\maven-compiler-plugin\3.1

2.若2.7.1目录下只有，"maven-compiler-plugin-3.1.pom.lastUpdated" 则需要到http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/3.1/，把里面的文件下载下来放到2.7.1，如果该仓库中没有，那么可以去http://search.maven.org/这个地方下载下来，然后放置到对应的本地仓库中

3.删除2.7.1下的maven-compiler-plugin-3.1.pom.lastUpdated文件。

4.项目右键-->maven-->Update Dependencies
