为什么我收到“使用GWT生命周期配置未涵盖的插件执行”错误？

Question

我正在使用STS，并从另一台机器导入了一个GWT项目。该项目使用m2eclipse。我在构建项目时遇到这两个错误：

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:gwt-maven-plugin:2.2.0:i18n (execution: default, phase: generate-sources) pom.xml /contactsgwt line 175 
Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-war-plugin:2.1.1:exploded (execution: default, phase: compile) pom.xml /contactsgwt line 198 

怎么了？是否需要进一步配置，以便gwt maven plugin工作？

的pom.xml代码导致错误：

如果你使用Eclipse靛蓝（3.7），你必须激活生命周期插件。 有关更多详细信息，请参见here。

只需添加这pluginManagement部分，将build节你pom.xml文件

<pluginManagement> 
    <plugins> 
     <plugin> 
      <groupId>org.eclipse.m2e</groupId> 
      <artifactId>lifecycle-mapping</artifactId> 
      <version>1.0.0</version> 
      <configuration> 
       <lifecycleMappingMetadata> 
        <pluginExecutions> 
         <pluginExecution> 
          <pluginExecutionFilter> 
           <groupId>org.codehaus.mojo</groupId> 
           <artifactId>gwt-maven-plugin</artifactId> 
           <versionRange>[2.4.0,)</versionRange> 
           <goals>

            <goal>compile</goal> 
            <goal>i18n</goal> 
            <goal>generateAsync</goal>

          </pluginExecutionFilter> 
          <action> 
           <execute />

         <pluginExecution>
