本文章来给各位同学介绍一下hadoop 1.1.2 eclipse plugin 编译，希望此文章对各位同学会有所帮助哦。
环境
代码如下
复制代码
[andy@s41 ~]$ echo $JAVA_HOME
/usr/java/jdk1.6.0_45
[andy@s41 ~]$ uname -a
Linux s41 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[andy@s41 ~]$ cat /etc/redhat-releaseCentOS release 6.4 (Final)
下载最新 eclipse
代码如下
复制代码
wget http://mirror.bit.edu.cn/eclipse/technology/epp/downloads/release/kepler/SR1/eclipse-standard-kepler-SR1-linux-gtk-x86_64.tar.gz
or
wget http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/kepler/SR1/eclipse-java-kepler-SR1-linux-gtk-x86_64.tar.gz&mirror_id=547
下载eclipse sdk 4.3.1
代码如下
复制代码
http://www.eclipse.org/eclipse4/
wget http://mirror.bit.edu.cn/eclipse/eclipse/downloads/drops4/R-4.3.1-201309111000/eclipse-SDK-4.3.1-linux-gtk-x86_64.tar.gz
解压到/home/andy目录下。
进入插件源码目录
代码如下
复制代码
[andy@s41 eclipse-plugin]$ pwd
/home/andy/hadoop-1.1.2/src/contrib/eclipse-plugin
修改build.properties,增加
代码如下
复制代码
eclipse.home=/home/andy/eclipse/
version=1.1.2
[andy@s41 eclipse-plugin]$ vi build.properties
output.. = bin/
bin.includes = META-INF/,
plugin.xml,
resources/,
classes/,
classes/,
lib/
eclipse.home=/home/andy/eclipse/
version=1.1.2
修改build.xml,增加fileset,复制两个jar文件到新目录
代码如下
复制代码
<path id=”eclipse-sdk-jars”>
<fileset dir=”../../../”>
<include name=”hadoop*.jar”/>
</fileset>
…
<target name=”jar” depends=”compile” unless=”skip.contrib”>
<!–
<copy file=”${hadoop.root}/build/hadoop-core-${version}.jar” tofile=”${build.dir}/lib/hadoop-core.jar” verbose=”true”/>
<copy file=”${hadoop.root}/build/ivy/lib/Hadoop/common/commons-cli-${commons-cli.version}.jar”todir=”${build.dir}/lib” verbose=”true”/>
–>
<copy file=”${hadoop.root}/hadoop-core-${version}.jar” tofile=”${build.dir}/lib/hadoop-core.jar” verbose=”true”/>
<copy file=”${hadoop.root}/lib/commons-cli-${commons-cli.version}.jar”todir=”${build.dir}/lib” verbose=”true”/>
[andy@s41 eclipse-plugin]$ ant
[andy@s41 hadoop-1.1.2]$ cp build/contrib/eclipse-plugin/hadoop-eclipse-plugin-1.1.2.jar ~/eclipse/plugins/
此前遇到如下错误，应是eclipse sdk和sdk版本不配套的问题。
代码如下
复制代码
