[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
?
经过一番百度之后build.xml添加绿色部分重新编译，放在eclipse的plugins目录下重启eclipse，便可以使用了
