推荐答案

您可以使用 /usr/libexec/java_home -v 获取JAVA_HOME.例如，要获取 1.7 JDK 的路径，您可以运行 /usr/libexec/java_home -v 1.7，它将返回 JDK 的路径.在您的 .profile 或 .bash_profile 中添加

You can use /usr/libexec/java_home -v <version you want> to get the path you need for JAVA_HOME. For instance, to get the path to the 1.7 JDK you can run /usr/libexec/java_home -v 1.7 and it will return the path to the JDK. In your .profile or .bash_profile just add

export JAVA_HOME=`/usr/libexec/java_home -v <version>`

你应该很好.或者，尝试说服您使用的 Java 工具的维护者使用此方法获取他们需要的版本.

and you should be good. Alternatively, try and convince the maintainers of java tools you use to make use of this method to get the version they need.

要打开.bash_profile"，请在终端中输入以下内容:

To open '.bash_profile' type the following in terminal :

nano ~/.bash_profile 

并将以下行添加到文件中:

and add the following line to the file:

export JAVA_HOME=`/usr/libexec/java_home -v <version>`

按 CTRL+X 退出 bash.按Y"保存更改.

Press CTRL+X to exit the bash. Press 'Y' to save changes.

要检查是否添加了路径，请在终端中输入以下内容:

To check whether the path has been added, type following in terminal:

source ~/.bash_profile
echo $JAVA_HOME
