[Zookeeper学习] 搭建Eclipse源码工程

简介

为更深入的研究Zookeeper，需要对源码进行深入研究。工欲善其事必先利其器，本文将介绍了在Windows+Eclipse环境下，如何构建源码的工程。

Ant工具安装

Zookeeper是通过ant工具进行构建的，我们需要安装配置ant工具。ant工具可以到官网下载http://ant.apache.org/。

作者使用的ant 1.99的版本。将下载的apache-ant-1.9.9-bin.tar.bz2解压到C:\apache-ant-1.9.9目录下。配置相关的环境变量：在环境变量中增加ANT_HOME=C:\apache-ant-1.9.9，在PATH中增加%ANT_HOME%\bin；打开命令行，输入"ant -version”查看配置是否正确：

Microsoft Windows [Version 6.1.7601]

C:\Users\jliu>ant -version
Apache Ant(TM) version 1.9.9 compiled on February 2 2017

Zookeeper工程构建

在http://www.apache.org/dyn/closer.cgi/zookeeper/下载Zookeeper源码，最新稳定的版本是3.4.10。将下载的zookeeper-3.4.10.tar.gz文件解压后，在相应的根目录下，有一个build.xml文件，它是ant的构建文件。

Volume in drive D has no label.
Volume Serial Number is 0005-6334

D:\zookeeper-3.4.10>ant eclipse
Buildfile: D:\zookeeper-3.4.10\build.xml

Eclipse导入工程

万事具备，只欠导入。打开Eclipse软件，使用File-->import-->General-->Existing Projects into Workspace-->Import--->Select root diretory选择Zookeeper的工作目录，选择Finish，导入成功：



大功告成！
