〖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 $1 in
10     jdk6 )
11         export JAVA_HOME=$jdk6_home
12         ;;
13     jdk7 )
14         export JAVA_HOME=$jdk7_home
15         ;;
16     jdk8 )
17         export JAVA_HOME=$jdk8_home
18         ;;
19     * )
20         export JAVA_HOME=$jdk6_home
21         ;;
22 esac
23 
24 export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
25 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)
