最近在搞hadoop，所以编译hadoop-eclipse插件是少不了的 ！
先说下我的编译环境：
hadoop: hadoop-2.5.2
OS：CentOS6.5 64位（VMWare虚拟机）
eclipse: eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz
1、下载源码
https://github.com/winghc/hadoop2x-eclipse-plugin
2.修改配置文件
libraries.properties
我的路径为：/usr/local/hadoop/hadoop2x-eclipse-plugin-master/ivy/libraries.properties

lib/jackson-mapper-asl-${jackson.version}.jar,
lib/slf4j-log4j12-${slf4j-log4j12.version}.jar,
lib/slf4j-api-${slf4j-api.version}.jar,标有“+”的部分是我加上的。
makePlus.sh
我的路径为/usr/local/hadoop/hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin/makePlus.sh
原内容：
ant jar -Dversion=2.0.4 -Declipse.home=/opt/eclipse -Dhadoop.home=/usr/share/hadoop
修改后
ant jar -Dversion=2.5.2 -Declipse.home=/home/hadoop/eclipse -Dhadoop.home=/home/hadoop/hadoop-2.5.2
使之可以执行
chmod +X makePlus.sh
3.编译
进入makePlus.sh所在目录，执行我们修改好的makePlus.sh文件 ./makePlus.sh
在这过程中有一步ivy-resolve-common很长时间没反应，我不清楚是死掉了还是在运行中所以就一直等啊等，上网查说这一步是很花时间的我也就没有在意，
可是都一下午了还是没有任何提示成功或者失败。我这一想有可能是网络不通，可是我的虚拟机是能联着网的，只有一种可能了，就是编译过程中需求去外国的网站下载所依赖的包，需要翻墙。想到这里我立马开个翻墙软件，再次执行 ./makePlus.sh，奇迹出现了！哈哈 编译成功了

[jar] Building jar: /home/hadoop/hadoop2x-eclipse-plugin/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.5.2.jar就是编译好的jar包所在路径了！
4.测试
把编译好的hadoop-eclipse-plugin-2.5.2.jar放在eclipse的plugins目录下，重启eclipse，配置好后发现不能 new hadoop location,现象是点击后没有任何反应。只好退出eclipse 在终端里进入eclipse 目录执行
./eclipse -clean -consolelog -debug
重新进入eclipse 点击 new hadoop location,查看终端里报出的异常信息java.lang.NoClassDefFoundError
build.xml添加绿色部分重新编译如下所示：
放在eclipse的plugins目录下重启eclipse，便可以使用了
