操作于 win7 32位  Eclipse 4.1  Kepler 

①下载插件源码包

https://github.com/winghc/hadoop2x-eclipse-plugin

点击右侧download下载

解压，打开解压目录“ xxxx\hadoop2x-eclipse-plugin-master\src\contrib”

②新建一个java项目

将contrib下的eclipse-plugin里面的内容拷贝到java项目下实际上只要拷贝5个就好。

META-INF
resources
src
build.properties
plugin.xml

拷贝完成了。那么问题来了：

全是红叉叉。。。(个人有很多红叉叉网上资料全都没有描述，解决后记录下。)

好像有个包名错了。。这个自己改吧- -不解释；

缺少一些jar包，(不小心放了汉化包。。以中文的描述吧问题不难，英文的相信你们对应的上)

缺少的第一部分jar包为"插件依赖项":右键项目->构建路径->配置构建路径->然后添加库->插件依赖项 下一步完成！

还有错。。。少jar包。

这个jar包不截图了大概就是少org.apache.hadoop.fs 类似的

大家都说去源码包lib下找到jar包全部引入就好。。。可是我的lib下面没有啊- -真的没有啊啊啊啊。。。

所以不要纠结了- -(认真你就输了,这个错误可以继续后续编译,编译完成了,jar包就来了所以不要在这些jar包上找方法了)。

③修改build.xml文件


 

 

 
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
     
    
        
            
        
        
        
        
        
        
        
        
        
            
    
     
    
        
    
     
    
        
        
        
        
        
            
            
            
            
        
        
            
            
            
        
        
            
            
            
        
        
            
            
            
        
        
            
            
            
            
            
            
            
            
            
            
            
            
            
            
            
        
        
     
    
        
        
            
            
        
    
        
        
        
            
        
        
        
            
        
        
        
        
    
    
        
        
    

修改前5项：

jdk.home指定编译时用的jdk，

hadoop和eclipse版本号是用来给jar起名字的，

hadoop.home是hadoop安装目录，会从里面提取需要的文件，

eclipse.home是eclipse的安装目录，MyEclipse中是那个Common目录。

everything is ok！ 右键build.xml文件Run AS Ant Build
