[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]Copyright (c) 2009 Microsoft Corporation.  All rights reserved.C:\Users\jliu>ant -versionApache 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。

D:\zookeeper-3.4.10>dir Volume in drive D has no label. Volume Serial Number is 0005-6334 Directory of D:\zookeeper-3.4.102017/03/23  19:28    <DIR>          .2017/03/23  19:28    <DIR>          ..2017/03/23  19:27    <DIR>          bin2017/03/23  18:14            84,725 build.xml2017/03/23  19:27    <DIR>          conf2017/03/23  18:14    <DIR>          contrib2017/03/23  19:36    <DIR>          dist-maven2017/03/23  19:27    <DIR>          docs2017/03/23  18:14             5,691 ivy.xml2017/03/23  18:14             1,709 ivysettings.xml2017/03/23  19:27    <DIR>          lib2017/03/23  18:14            11,938 LICENSE.txt2017/03/23  18:14             3,132 NOTICE.txt2017/03/23  18:14             1,585 README.txt2017/03/23  18:14             1,770 README_packaging.txt2017/03/23  18:14    <DIR>          recipes2017/03/23  19:27    <DIR>          src2017/03/23  19:24         1,456,729 zookeeper-3.4.10.jar2017/03/23  19:28               819 zookeeper-3.4.10.jar.asc2017/03/23  19:24                33 zookeeper-3.4.10.jar.md52017/03/23  19:24                41 zookeeper-3.4.10.jar.sha1              11 File(s)      1,568,172 bytes              10 Dir(s)  74,583,306,240 bytes free

查看build.xml文件内容，会发现有一个eclipse的目标标签，这个标签就是用来配置生成Eclipse工程文件的。那就赶紧开始构建吧：

D:\zookeeper-3.4.10>ant eclipseBuildfile: D:\zookeeper-3.4.10\build.xmlant-eclipse-download:      [get] Getting: http://downloads.sourceforge.net/project/ant-eclipse/ant-eclipse/1.0/ant-eclipse-1.0.bin.tar.bz2      [get] To: D:\zookeeper-3.4.10\src\java\ant-eclipse-1.0.bin.tar.bz2      [get] http://downloads.sourceforge.net/project/ant-eclipse/ant-eclipse/1.0/ant-eclipse-1.0.bin.tar.bz2 moved to http://124.205.69.168/files/A003000001AAB616/downloads.sourceforge.net/project/ant-eclipse/ant-eclipse/1.0/ant-eclipse-1.0.bin.tar.bz2  [bunzip2] Expanding ant-eclipse-1.0.bin.tar.bz2 to D:\zookeeper-3.4.10\src\java\ant-eclipse-1.0.bin.tar    [untar] Expanding: D:\zookeeper-3.4.10\src\java\ant-eclipse-1.0.bin.tar into D:\zookeeper-3.4.10\src\java   [delete] Deleting: D:\zookeeper-3.4.10\src\java\ant-eclipse-1.0.bin.tar   [delete] Deleting: D:\zookeeper-3.4.10\src\java\ant-eclipse-1.0.bin.tar.bz2

构建完成以后，在根目录下会生成.project和.classpath文件：

 Volume in drive D has no label. Volume Serial Number is 0005-6334 Directory of D:\zookeeper-3.4.102017/06/22  09:05    <DIR>          .2017/06/22  09:05    <DIR>          ..2017/06/22  09:05            10,774 .classpath2017/06/22  09:05               393 .project2017/06/22  09:05    <DIR>          .revision2017/06/22  09:05    <DIR>          .settings2017/03/23  19:27    <DIR>          bin2017/06/22  09:04    <DIR>          build2017/03/23  18:14            84,725 build.xml2017/03/23  19:27    <DIR>          conf2017/03/23  18:14    <DIR>          contrib2017/03/23  19:36    <DIR>          dist-maven2017/03/23  19:27    <DIR>          docs2017/03/23  18:14             5,691 ivy.xml2017/03/23  18:14             1,709 ivysettings.xml2017/03/23  19:27    <DIR>          lib2017/03/23  18:14            11,938 LICENSE.txt2017/03/23  18:14             3,132 NOTICE.txt2017/03/23  18:14             1,585 README.txt2017/03/23  18:14             1,770 README_packaging.txt2017/03/23  18:14    <DIR>          recipes2017/03/23  19:27    <DIR>          src2017/03/23  19:24         1,456,729 zookeeper-3.4.10.jar2017/03/23  19:28               819 zookeeper-3.4.10.jar.asc2017/03/23  19:24                33 zookeeper-3.4.10.jar.md52017/03/23  19:24                41 zookeeper-3.4.10.jar.sha1              13 File(s)      1,579,339 bytes              13 Dir(s)  74,561,110,016 bytes free

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！
