Point eclipse IDE to use another JRE / JDK other than one specified in JAVA_HOME

Question

I am having two JRE / SDK in my development environment, however it was necessary in my situation to set JAVA_HOME to 1.4.2, this is causing my eclipse IDE to stop running as it required 1.6 and above.

May i know how i can modify eclipse ini or environment home to use my other 1.6 installation?

Please try the eclipse.ini entry above the varargs (the following two lines must be two lines in the eclipse.ini file)

-vm
C:\Java\JDK\1.5\bin\javaw.exe

Find the JVM

Also to add that this needs to be above the varargs parameter. Thanks! – Oh Chin Boon Jul 30 '11 at 09:50

Note that the path needs to be on a separate line, eclipse.ini is rather particular about its format. – Matthew Wise Feb 20 '15 at 15:01
You must use back slash, and put it a line after -vm, and then -vmargs . Like that -vm C:/Program Files/Java/jre7/bin/javaw.exe -vmargs – Natan Lotério Apr 21 '16 at 20:39

Right click the project in Package Explorer -> Configure Build Path

Add Library -> JRE System Library

Set JRE system library to JDK

Verify JDK is the reference library

From the menu in the top.. Proceed as follows--

Project-->Properties--> Java Build Path--> Libraries--> JRE System Library.

Now click Edit . Select Alternate JRE. Click Installed JRE. Provide path to your other JDK. Then FINISH.

That's it.
