2. Plugin execution not covered by lifecycle configuration

问题：

 

 

找到当前项目的工作空间下的.metadata\.plugins\org.eclipse.m2e.core路径，

然后添加lifecycle-mapping-metadata.xml文件,内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
  <pluginExecutions>
    <pluginExecution>
      <pluginExecutionFilter>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <goals>
          <goal>timestamp-property</goal>
        </goals>
        <versionRange>[0.0,)</versionRange>
      </pluginExecutionFilter>
      <action>
        <ignore />
      </action>
    </pluginExecution>
  </pluginExecutions>
</lifecycleMappingMetadata>
