生命周期错误未涵盖插件执行

Question

下面是我的pom.xml代码段

<parent> ---Getting Error Here
<groupId>com.Brink</groupId>
<artifactId>scheduler</artifactId>
<version>${revision}</version>
</parent>

错误是：Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:flatten-maven-plugin:1.0:flatten (execution: flatten, phase: process-resources)

我现在好吗，这是怎么了？

谢谢
