linux下，手动切换jdk
1、首先将自定义的jdk目录安装到alternatives中
seven@ThinkPad:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/java java /home/seven/Documents/Android/jdk1.6.0_45/bin/java 700
seven@ThinkPad:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/javac javac /home/seven/Documents/Android/jdk1.6.0_45/bin/javac 700
seven@ThinkPad:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/jar jar /home/seven/Documents/Android/jdk1.6.0_45/bin/jar 700
seven@ThinkPad:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/javah javah /home/seven/Documents/Android/jdk1.6.0_45/bin/javah 700
2、选择
seven@ThinkPad:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --config java//可以是javac、javah、jar[sudo] password for seven: There are 2 choices for the alternative java (providing /usr/bin/java).
