hadoop2.5.2eclipse插件编译

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：ubuntu 14.4 64位（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-

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：ubuntu 14.4 64位（虚拟机）

eclipse: eclipse-jee-luna-SR1-linux-gtk-x86_64.tar.gz

1.下载源码：

2.修改配置文件

libraries.properties

以上以标有“=”的部分我修改为

 lib/commons-cli-${commons-cli.version}.jar, lib/commons-configuration-${commons-configuration.version}.jar, lib/commons-httpclient-${commons-httpclient.version}.jar, lib/commons-lang-${commons-lang.version}.jar, lib/jackson-core-asl-${jackson.version}, lib/jackson-mapper-asl-${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

原文件内容

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。无奈，拿起qq搜了几个hadoop的群，进去问下，有人说慢很正常，网络卡顿了吧。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

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
