Maven Plugin execution not covered by lifecycle configuration

报错

配置私服之后，pom文件报错

Multiple annotations found at this line:- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (execution: default-compile, phase:  compile)- CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.5.1 or one of its dependencies could not be  resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.5.1: ArtifactResolutionException: Failure to transfer  org.apache.maven.plugins:maven-compiler-plugin:pom:2.5.1 from http://localhost:8081/nexus/content/groups/public/ was cached in the local repository, resolution  will not be reattempted until the update interval of nexusMirror has elapsed or updates are forced.

问题原因

无法下载maven插件或没有配置插件

解决办法

在pom.xml中添加如下配置，然后右键工程，选择“maven”-->‘Update ProjectConfiguration...’
