Suppose I need to change java version to 8, then i change the key value of JAVA_HOME. Login as admin user if you are a domain user.Įdit Environment variables -> Advanced -> System Variables -> NEW:Ī) Add multiple entries for JAVA_HOME as below:- JAVA_HOME (in my case, its version 11 is by default),ī) now edit Path under same System variables and add NEW path for java as below. I been doing this by replacing JAVA_HOME variable in Environment variables - System Properties only. Set JAVA_HOME=C:\Program Files\Java\jdk-15.0.2+7 Set JAVA_HOME=C:\Program Files\Java\jdk8u282-b08 Adding batch file location path to system environmental variables will allow you to execute it from cmd. Find my python environment settings here.įound a single batch file to be a simpler solution. If you're using different Python versions, same trick applies, too. Environment changes only happens to new CMD. This is because your changes will not affect opened cmd window. Close any command prompt you're using or just open a new command prompt. So, whenever a command prompt is opened, it automatically loads profile.bat, which creates those two alias in the script. Here, please put your actual path value to the profile.bat we just created.
Give AutoRun as the Value name and %USERPROFILE%\profile.bat as the Value data. Every time, java8 or java9 is called, it re-exports %PATH% with the new JDK path. In batch file any string after :: is the comments. In order to switch JDK version in cmd, here's the trick.ĭOSKEY java8=SET PATH=%JAVA_8_HOME% %PATH% ĭOSKEY java9=SET PATH=%JAVA_9_HOME% %PATH%īasically, it disables echo and creates two alias.
%JAVA_HOME% will be added to PATH automatically every time you launch a command prompt.

That's my preference, feel free to adjust accordingly. %JAVA_HOME% has a default value pointing to JAVA_8_HOME, which is the path for JDK8. You can replace this with your own path to javac. In my case, JAVA_8_HOME(JDK8) is pointing to C:\Program Files\Java\jdk1.8.0_152\bin.
