maven错误:org/apache/maven/shared/filtering/MavenFilteringException 解决方法

问题描述

电脑重启后不知道为啥eclipse中的maven不能用了，pom文件一直标红，报以下错误：

Execution default-cli of goal org.apache.maven.plugins:maven-resources-plugin:2.5:copy-resources failed: A required class was missing while executing org.apache.maven.plugins:maven-resources-plugin:2.5:copy-resources: org/apache/maven/shared/filtering/MavenFilteringException

-----------------------------------------------------
realm =    plugin>org.apache.maven.plugins:maven-resources-plugin:2.5
strategy = org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy
urls[0] = file:/C:/Users/admin/.m2/repository/org/apache/maven/plugins/maven-resources-plugin/2.5/maven-resources-plugin-2.5.jar
urls[1] = file:/C:/Users/admin/.m2/repository/org/codehaus/plexus/plexus-utils/1.1/plexus-utils-1.1.jar
Number of foreign imports: 1

import: Entry[import  from realm ClassRealm[maven.api, parent: null]]

但是在.m2下maven插件：maven-resources-plugin的确是存在的，而且版本号的确是2.5

解决办法

在pom文件中增加：

    <plugins>
        <plugin>  
   <groupId>org.apache.maven.plugins</groupId>  
   <artifactId>maven-resources-plugin</artifactId>  
   <version>2.4.3</version>  
   <configuration>  
       <encoding>utf-8</encoding>  
   </configuration>  
</plugin> 
    </plugins>

具体原因以后再查。
