生命周期配置maven错误未涵盖插件执行

Question

生命周期配置maven错误未涵盖插件执行

我导入了一个现有的maven项目但是我在pom.xml中遇到了一些错误:

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-

 compiler-plugin:2.3.2:compile (execution: default-compile, phase: compile) pom.xml 

 /org.squashtest.csp.tools.unittest line 50 Maven Project Build Lifecycle Mapping Problem

但我不明白为什么,

这是pom.xml:
