  昨天折腾hadoop2X的eclipse插件,从https://github.com/winghc/hadoop2x-eclipse-plugin把源码搞下来后,很快搞定出来一个,但是。。。New Hadoop Location时,窗口出不来,汗死,原因后面会说明的。源码难下,最后我会附上源码包的。

  仔细看了ant和ivy的文件之后,我发现了一个坑爹的现象,编译一个插件,需要ivy么?!

  ant用了好久了,还是自己写一个的好。

  查看了jar包,都是hadoop安装目录里面存在的,还需要连个毛线的网去检测啊!看了下ivy的调试信息,也就那么些东西,直接干掉ivy!

  重新写了个build.xml,只要往目录hadoop2x-eclipse-plugin-master/src/contrib/eclipse-plugin里面一丢,改改前5个属性的值,直接跑“ant jar”就行了。

  或者eclipse建立一个普通项目,把

META-INF
resources
src
build.properties
plugin.xml

往项目一丢,再把build.xml丢进去,改了前5个属性值直接跑就行了。

  build.xml内容如下

<?xml version="1.0"?>

  最前面5个属性中,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。

  原版中坑爹的jar包版本号无视了,MANIFEST.MF的classpath值也懒得去改了,都自动了,虽然自动会多了几个值,但是总比少的好。

  又回到最开始的问题,new hadoop location时的窗口问题,是因为少了commons-collections包,所以直接从hadoop安装目录把这个包拉进来打包了,然后问题解决!

  用jdk1.6编译了两个插件包,MyEclipse10的和Eclipse4.4的,都能用。至于上传文件时由于当前用户名导致的权限问题,这个就是改配置或改代码的事情了,我是编译前直接在源码里面加了两行,反正插件随便编译一下就有了。

  最后附上官方源码,里面原先那个打包好的插件干掉了,都是旧的,还巨大无比!下载源码包
