eclipse載入maven工程提示pom.xml無法解析org.apache.maven.plugins:maven-resources-plugin:2.4.3解決方案

在別的機子上建立一個maven工程，複製到本機上匯入，出現pom.xml檔案錯誤，提示錯誤如下

錯誤資訊出現在pom頭的project標籤，project標籤內容是

<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

這是由於缺少maven-resources-plugin-2.4.3.jar檔案。這個檔案是在{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\下。{user.home}是maven的配置路徑，一般是我的文件，是window-preferences-MyEclipse-Maven4MyEclipse-User Setting裡面的Local Repository。

解決方案

1、在pom.xml檔案中加入maven-resources-plugin配置

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

2、在命令列下運行 mvn install  ，如果執行正確應該會在{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\下看到maven-resources-plugin-2.4.3.jar檔案

3、重新整理工程（右鍵工程選擇重新整理項）

4、重新整理maven配置，右鍵工程節點，選擇Maven4MyEclipse-Update Project Configuration
