 eclipse.ini

Eclipse startup is controlled by the options in $ECLIPSE_HOME/eclipse.ini. If $ECLIPSE_HOME is not defined, the default eclipse.ini in your Eclipse installation directory is used.

eclipse.ini is a text file containing command-line options that are added to the command line used when Eclipse is started up. Important: Each option and each argument to an option must be on its own line.

By default, eclipse.ini contains something like

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms40m
-Xmx256m

which sets the heap space to 40MB initially and a maximum of 256MB, and also specifies a maximum PermGen size of 256MB.


One of the most recommended options to use is to specify a specific JVM for Eclipse to run on. The following eclipse.ini demonstrates correct usage of the -vm option:

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
C:\Java\JDK\1.5\bin\javaw.exe
-vmargs
-Xms40m
-Xmx512m
