eclipse加载maven工程提示pom.xml无法解析

在别的机子上创建一个maven工程，复制到本机上导入，出现pom.xml文件错误，提示错误如下

错误信息出现在pom头的project标签，project标签内容是

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

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

<dependency><groupId></groupId><artifactId></artifactId><version></version></dependency>

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
