原因

这是由于缺少maven-resources-plugin-2.4.3.jar文件。这个文件是在{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\下。{user.home}是maven的配置路径，一般是我的文档，是window-preferences-MyEclipse-Maven4MyEclipse-User Setting里面的Local Repository。

解决方案

1、在pom.xml文件中加入maven-resources-plugin配置

    org.apache.maven.plugins
    maven-resources-plugin
    2.4.3

2、在命令行下运行 mvn install  ，如果执行正确应该会在{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\下看到maven-resources-plugin-2.4.3.jar文件

3、刷新工程（右键工程选择刷新项）

4、刷新maven配置，右键工程节点，选择Maven4MyEclipse-Update Project Configuration
