Specifying the JVM Eclipse should use is both a nice way to make sure it is correct now and to know that future upgrades/updates won’t mess with this.
This is done by specifying the -vm option in the “eclipse.ini” file.
Important bits to know about this:
- -vm option and the path must not be on the same line
- You should give the Java excecutable here, not just the path where is is located
- if you also have -vmargs the -vm must be before that in the ini file
Example eclipse.ini (for windows)
-startup plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile --launcher.XXMaxPermSize 256M -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m --launcher.defaultAction openFile -vm C:\progra~1\Java\jdk1.6.0_26\bin\javaw.exe -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx512m
