1、下載插件源碼
https://github.com/winghc/hadoop2x-eclipse-plugin
2、下載ant1.10.1
http://mirrors.tuna.tsinghua.edu.cn/apache//ant/binaries/apache-ant-1.10.1-bin.tar.gz
3、配置ant環境變量
E:\apache-ant-1.10.1-bin\apache-ant-1.10.1
path：增加%ANT_HOME%\bin
%JAVA_HOME%\bin;%M2_HOME%\bin;%ANT_HOME%\bin;----
4、下載hadoop-2.7.5和hadoop2x-eclipse-plugin插件，解壓
5、配置編譯插件
進入到hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin\build.xml文件中，找到
<target
name="jar" depends="compile" unless="skip.contrib">這一行
往下找
<copy
file="${hadoop.home}/share/hadoop/common/lib/htrace-core-${htrace.version}.jar" todir="${build.dir}/lib" verbose="true"/>
修改爲
<copy
file="${hadoop.home}/share/hadoop/common/lib/htrace-core-${htrace.version}-incubating.jar" todir="${build.dir}/lib" verbose="true"/>
然後在此之後再增加以下兩行
<copy
file="${hadoop.home}/share/hadoop/common/lib/servlet-api-${servlet-api.version}.jar" todir="${build.dir}/lib" verbose="true"/>
<copy file="${hadoop.home}/share/hadoop/common/lib/commons-io-${commons-io.version}.jar" todir="${build.dir}/lib" verbose="true"/>
然後再找到
<jar
jarfile="${build.dir}/hadoop-${name}-${hadoop.version}.jar"
manifest="${root}/META-INF/MANIFEST.MF">
<manifest>
<attribute name="Bundle-ClassPath"
value="classes/, ------------這一行
追加以下兩行
lib/servlet-api-${servlet-api.version}.jar,
lib/commons-io-${commons-io.version}.jar,
並將lib/htrace-core-${htrace.version}.jar
替換爲lib/htrace-core-${htrace.version}-incubating.jar
6、hadoop2x-eclipse-plugin-master\src\ivy\libraries.properties文件中，更改下列屬性和其值使其對應hadoop2.7.5和當前環境的jar包版本，按以下配置文件中的版本好：
hadoop.version=2.7.2 ------Hadoop版本號
apacheant.version=1.10.1 -------ant版本號
commons-collections.version=3.2.2
commons-httpclient.version=3.1
commons-logging.version=1.1.3
commons-io.version=2.4
slf4j-api.version=1.7.10
slf4j-log4j12.version=1.7.10
7. hadoop2x-eclipse-plugin-master\ivy\libraries.properties文件中，屬性和值的修改同上面的2.。另外需要增加一個修改：
htrace.version=3.1.0
8、然後執行
ant
jar -Dversion=2.7.5 -Declipse.home=D:\eclipseOXY\eclipse-jee-oxygen-R-win32-x86_64\eclipse -Dhadoop.home=E:\Hadoop\hadoop-2.7.5
-Declipse.home是eclipse路徑
-Dhadoop.home是Hadoop所在路徑
如果遇到ivy-resolve-common:位置會有短暫的停頓，等待即可。一般不會超過2分鐘，如果時間太長，中斷操作，然後檢查配置文件是否出錯
正常編譯通過如下：
check-contrib:
init:
[echo] contrib: eclipse-plugin
init-contrib:
ivy-probe-antlib:
ivy-init-antlib:
ivy-init:
