I’m working on few projects and some of them are using different JDK. Switching between JDK versions is not comfortable. So I was wondering if there is any easy way to change it?
I found 2 ways, which should solve this problem, but it doesn’t work.
First solution is creating a bat files like this:
@echo off echo Setting JAVA_HOME set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_72 echo setting PATH set PATH=C:\Program Files\Java\jdk1.7.0_72\bin;%PATH% echo Display java version java -version pause
And after running this bat, I see right version of Java. But when I close this CMD and open a new one and type “java -version” it says that I still have 1.8.0_25. So it doesn’t work.
Second solution which I found is an application from this site. And it also doesn’t work. The same effect as in the first solution.
Any ideas? Because changing JAVA_HOME and PAHT by: Win + Pause -> Advanced System Settings -> Environment Variables -> and editing these variables, is terrible way…
set command only works for the current terminal. To permanently set a system or user environment variable you can use
setx JAVA_HOME "C:\Program Files\Java\jdk1.7.0_72" /m
/m option is used to set the variable system wide (and not just for the current user). The terminal must be run as administrator to use this option.
The variable will be available in all new terminal windows, but not the current one. If you want to display the path in the same window, you need to use both
You can avoid manipulating the
PATH variable if you just once put
%JAVA_HOME% in there, instead of the full JDK path. If you change
PATH will be updated too.
There are also a few environment variable editors as alternative to the cumbersome Windows environment variable settings. See “Is there a convenient way to edit PATH in Windows 7?” on Super User.
