变化JDK版本在倍频上MAC

我用

ml_jar_version=javaMethod('getProperty','java.lang.System','java.version'); 
ml_jar_version=['Java ' ml_jar_version];

检查Java版本，我得到了

ml_jar_version = Java 1.6.0_65

然而，我想八度使用JDK 1.7，所以我打字

setenv("JAVA_HOME","/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home");

，但ml_jar_version没有变化。

我的问题是：如何使Octave使用JDK 1.7？

编辑1：我的Octave是通过自制软件安装的。我相信自制软件只是下载了预编译的二进制文件。以下是我八度的安装配置：

homebrew/science/octave: stable 3.8.2 (bottled), HEAD 
a high-level interpreted language for numerical computations.

你怎么安装八度？你自己编译过吗？怎么样？你使用过二进制安装程序吗？哪一个？ –

@LudwigSchulze，我通过自制软件安装了Octave。有关详细信息，请参阅我的编辑1. – wdg

尝试重现自制八度安装我碰到一个错误：brew tap homebrew/science;酿造更新; brew install octave - >安装依赖关系时发生错误“suite-sparse”：404 for http://www.cise.ufl.edu/research/sparse/SuiteSparse/SuiteSparse-3.7.0.tar.gz –

看来，倍频读取符号链接 'dafault的Java'，在这里： /usr/lib中/ JVM /默认的Java

$ls -al 

drwxr-xr-x 5 root root 4096 нов 19 21:37 . 
drwxr-xr-x 181 root root 12288 нов 19 20:45 .. 
lrwxrwxrwx 1 root root 14 нов 19 21:37 default-java -> java-8-openjdk-amd64/ 
lrwxrwxrwx 1 root root 20 апр 23 2016 java-1.8.0-openjdk-amd64 -> java-8-openjdk-amd64 
-rw-r--r-- 1 root root 2600 окт 27 21:06 .java-1.8.0-openjdk-amd64.jinfo 
drwxr-xr-x 8 root root 4096 нов 19 20:45 java-7-oracle 
-rw-r--r-- 1 root root 2543 нов 19 20:45 .java-7-oracle.jinfo 
drwxr-xr-x 7 root root 4096 нов 19 21:37 java-8-openjdk-amd64 
drwxr-xr-x 2 root root 4096 нов 16 20:28 openjdk-8

你需要改变它指向你的java文件夹：

首先将其删除：

$sudo rm default-java

然后创建一个新的符号链接（java的7-甲骨文在我的情况）：

$ln -s java-7-oracle/ default-java

这之后768,16工作。

在八度：

>> javaMethod('getProperty','java.lang.System','java.version') 
ans = 1.7.0_80
