Eclipse startup is controlled by the options in
$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.
- Each option and each argument to an option must be on its own line.
- All lines after
-vmargsare passed as arguments to the JVM, so all arguments and options for eclipse must be specified before
-vmargs(just like when you use arguments on the command-line)
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 (for a Windows system):
-showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vm C:\Java\JDK\1.5\bin\javaw.exe -vmargs -Xms40m -Xmx512m
On a Linux system, the file looks quite similar:
-showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vm /opt/sun-jdk-1.6.0.02/bin/java -vmargs -Xms40m -Xmx512m
On a Mac OS X system, to specify Java 6:
-showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vm /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java -vmargs -Xms40m -Xmx512m
Note the format as it is important to be exact:
-vmoption and its value (the path) must be on separate lines.
- The value must be the full absolute path to the Java executable, not just to the Java home directory.
