M2E plugin execution not covered

从git上面clone一个项目到本地，经常会遇到
M2E plugin execution not covered的error，此error在eclipse的wiki上已经说明得很清楚了,我来写一下我的理解。
http://wiki.eclipse.org/M2E_plugin_execution_not_covered

出错原因：
m2eclipse会自动build pom.xml里面的部分内容，然后project的配置是基于build 完pom.xml之后的。（按理来说，我们执行mvn命令，都是直接在shell中通过命令行去执行，不会在eclipse里面对项目进行打包，发布等）。不幸的是，m2eclipse有一个长久以来一直存在的bug，就是eclipse在做自动的build pom.xml时会经常无规律的报错，好在m2eclipse提供了quickfix可以用。

解决方案：
1.推荐的方案：为Plugin加一个configuration标签如下，以做到让eclipse去忽略这个plugin（这个不用自己写，quickfix中选择“permanently mark goal as ignored in eclipse”,注意此修改只影响eclipse，不会影响项目的正常build）

<pluginManagement>
<plugins>
<plugin>
 <groupId>org.eclipse.m2e</groupId>
 <artifactId>lifecycle-mapping</artifactId>
 <version>1.0.0</version>
 <configuration>
   <lifecycleMappingMetadata>
     <pluginExecutions>
       <pluginExecution>
         <pluginExecutionFilter>
           <groupId>some-group-id</groupId>
           <artifactId>some-artifact-id</artifactId>
           <versionRange>[1.0.0,)</versionRange>
           <goals>
             <goal>some-goal</goal>
           </goals>
         </pluginExecutionFilter>
         <action>
           <ignore />
         </action>
       </pluginExecution>
     </pluginExecutions>
   </lifecycleMappingMetadata>
 </configuration>
</plugin>
</plugins>
</pluginManagement>

2. 增加configuration，里面的execute是告诉eclipse当java类方式修改时是否执行action.这里把它设为否。除非对这个plugin非常了解，的确可以设为false,否则不推荐用此方法。

<pluginManagement>
<plugins>
<plugin>
 <groupId>org.eclipse.m2e</groupId>
 <artifactId>lifecycle-mapping</artifactId>
 <version>1.0.0</version>
 <configuration>
   <lifecycleMappingMetadata>
     <pluginExecutions>
       <pluginExecution>
         <pluginExecutionFilter>
           <groupId>some-group-id</groupId>
           <artifactId>some-artifact-id</artifactId>
           <versionRange>[1.0.0,)</versionRange>
           <goals>
             <goal>some-goal</goal>
           </goals>
         </pluginExecutionFilter>
         <action>
           <execute >
             <runOnIncremental>false</runOnIncremental>
           </execute >
         </action>
       </pluginExecution>
     </pluginExecutions>
   </lifecycleMappingMetadata>
 </configuration>
</plugin>
</plugins>
</pluginManagement>

3. 在eclipse里面设置，首先在Windows -> Preferences -> Maven -> Lifecycle mapping里面选择change mapping file location，在里面配置需要ignore的goal.

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
