Mac安装Java配置JAVA_HOME

1. 进入Oracle官网JAVA的下载界面,找到自己需要下载的JDK版本。点选“Accept License Agreement”后,选择自己电脑的下载包(Mac OS X x64)并单击该包进行下载。

jdk-8u66-macosx-x64.dmg

2. 配置JAVA_HOME

装完之后发现在默认的路径下找不到JDK7的HOME,如下所示:

$ which java

/usr/bin/java

$ ls -l /usr/bin/java

lrwxr-xr-x  1 root  wheel  74 10 26 22:55 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

$ ls -l /System/Library/Frameworks/JavaVM.framework/Versions

total 64

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.4 -> CurrentJDK

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.4.2 -> CurrentJDK

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.5 -> CurrentJDK

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.5.0 -> CurrentJDK

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.6 -> CurrentJDK

lrwxr-xr-x  1 root  wheel   10 10 26 22:55 1.6.0 -> CurrentJDK

drwxr-xr-x  7 root  wheel  238 10 26 22:55 A

lrwxr-xr-x  1 root  wheel    1 10 26 22:55 Current -> A

lrwxr-xr-x  1 root  wheel   52 10 26 22:55 CurrentJDK -> /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

解决:

google了一下,发现了这篇文章Important Java Directories on Mac OS X,可以使用工具命令“/usr/libexec/java_home”来定位JAVA_HOME

vim ~/.bash_profile

加入:

JAVA_HOME=`/usr/libexec/java_home`  

export JAVA_HOME

 

另外可以使用-V选项列出所有版本的JAVA_HOME:

$ /usr/libexec/java_home -V

Matching Java Virtual Machines (3):

    1.8.0_66, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home

    1.6.0_65-b14-468, x86_64: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

    1.6.0_65-b14-468, i386: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home

 

最后不要忘记,如果.bash_profile是刚刚创建的,需要这一句让配置生效:

source .bash_profile

验证:

$ echo $JAVA_HOME

/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home
