java.lang.NoClassDefFoundError: org/apache/maven/shared/filtering/MavenFiltering

今天通过maven编译项目时，发现org/apache/maven/shared/filtering/MavenFilteringException 不存在。于是找到本地仓库 发现reosurce plugin没有下载下来。于是通过检查pom.xml找到的错误的原因。

 

错误信息：

解决方案:
1.出现此错误时一定是download resource插件时，maven私服上没有这个版本的插件.现在存在的resource插件版本为2.4.3可以改成这个版本试试.

<plugin>  
    <groupId>org.apache.maven.plugins</groupId>  
    <artifactId>maven-resources-plugin</artifactId>  
    <version>2.4.3</version>  
    <configuration>  
        <encoding>${project.build.sourceEncoding}</encoding>  
    </configuration>  
</plugin>  

 

2.我出现的原因是因为子项目没有引用服务项目的plugin插件导致maven会默认自动下载resource插件 而新版本的resource插件不存在.所以报了如上的错误
解决方案把plugin插件添加到子项目中然后指定插件版本号即可.
