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。

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\下看到maven-resources-plugin-2.4.3.jar文件
