〖Linux〗多个JDK版本之间快速切换

由于工作的需要,经常要切换JDK版本比如我HOME目录下有三个JDK版本:

~/apt/jdk1.6.0_34 # JDK6~/apt/jdk1.7.0_67 # JDK7~/apt/jdk1.8.0_05 # JDK8

比如编译Android整套系统源代码,Google建议使用JDK6

在实现的工作中,由于项目的实际需求,要使用JDK7来执行一些工具

 

为了方便切换JDK版本,我写了一个脚本:

 1 #!/bin/sh 2 # usage: . this_file [argvs] 3  4 jdk6_home=~/apt/jdk1.6.0_34 5 jdk7_home=~/apt/jdk1.7.0_67 6 jdk8_home=~/apt/jdk1.8.0_05 7  8 # 默认JDK6 9 case $1 in10     jdk6 )11         export JAVA_HOME=$jdk6_home12         ;;13     jdk7 )14         export JAVA_HOME=$jdk7_home15         ;;16     jdk8 )17         export JAVA_HOME=$jdk8_home18         ;;19     * )20         export JAVA_HOME=$jdk6_home21         ;;22 esac23 24 export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH25 export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

使用方法:

  例如:在需要切换的JDK7的时候,在Shell中执行  . [脚本文件名] jdk7 

  前提:把JDK7下载并解压到 ~/apt/jdk1.7.0_67(根据自身需求修改)
