Perché ricevo un errore di "esecuzione del plugin non coperto dalla configurazione del ciclo di vita con GWT"?

Question

Sto usando STS e ho importato un progetto GWT da un'altra macchina. Il progetto utilizza m2eclipse. Ricevo questi due errori durante la creazione del progetto:

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 

Cosa c'è che non va? C'è qualche ulteriore configurazione da fare in modo che lo gwt maven plugin funzioni?

Il codice pom.xml che causa l'errore:

Se si utilizza Eclipse Indigo (3.7) si deve attivare il plugin ciclo di vita. Vedere here per ulteriori dettagli.

Basta aggiungere questa sezione pluginManagement alla sezione build del file pom.xml

<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>resources</goal> 
            <goal>compile</goal> 
            <goal>i18n</goal> 
            <goal>generateAsync</goal> 
           </goals> 
          </pluginExecutionFilter> 
          <action> 
           <execute /> 
          </action> 
         </pluginExecution> 
         <pluginExecution> 
          <pluginExecutionFilter> 
           <groupId>org.apache.maven.plugins</groupId> 
           <artifactId>maven-war-plugin</artifactId> 
           <versionRange>[2.1.1,)</versionRange> 
           <goals> 
            <goal>exploded</goal> 
           </goals> 
          </pluginExecutionFilter> 
          <action> 
           <execute /> 
          </action> 
         </pluginExecution> 
        </pluginExecutions>
