[email protected]:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/javac javac /home/seven/Documents/Android/jdk1.6.0_45/bin/javac 700
[email protected]:~/srcAndroid/src4.4.4_r1$ sudo update-alternatives --install /usr/bin/jar jar /home/seven/Documents/Android/jdk1.6.0_45/bin/jar 700
[email protected]:~/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
[email protected]:~/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). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode * 1 /home/seven/Documents/Android/jdk1.6.0_45/bin/java 700 manual mode 2 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode Press <enter> to keep the current choice[*], or type selection number:
3、验证
[email protected]:~/srcAndroid/src4.4.4_r1$ java -version java version "1.6.0_45" Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode) [email protected]:~/srcAndroid/src4.4.4_r1$
