A path ending in "bin", pointing to the "bin" directory of the Java distro works, and Ed Merks tells me that pointing to a "shared library" works also. TODO: I know this next statement is not completely true, I just don't know the exact answer.
Many a user has been tripped up because they thought they knew what JVM would be used by default, but they thought wrong. Doing this ensures that you are absolutely certain which JVM Eclipse will run in and insulates you from system changes that can alter the "default" JVM for your system. One of the most recommended options to use is to specify a specific JVM for Eclipse to run on. A max heap of 512MB might be OK for some users, but it's often necessary to bump that value up for large project sets or when some third-party plugins are installed. /./plugins/.86_64_1.1.100.v20110502Īmong other things, this sets the heap space to 40MB initially and a maximum of 512MB, and also specifies a maximum PermGen size of 256MB. Make a backup-keep a copy of the original contents on hand so you don't break your installation and have to download it all again.īy default, eclipse.ini looks something like this (the exact contents will vary based on operating system and which Eclipse package you have):.If the JVM keeps exiting with code 2 instead of starting Eclipse, try removing them. -XX VM arguments are subject to change without notice, even during minor updates.ini file unless -launcher.appendVmargs is specified either in the. Any use of -vmargs on the command-line replaces all -vmargs settings in the.All lines after -vmargs are 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).Each option and each argument to an option must be on its own line.You can, and should, experiment with changes to the launch command from your Command Prompt/Terminal before changing the eclipse.ini itself.There are many options available, please see here. If $ECLIPSE_HOME is not defined, the default eclipse.ini in your Eclipse installation directory (or in the case of Mac, the Eclipse.app/Contents/MacOS directory) is used.Įclipse.ini is a text file containing command-line options that are added to the command line used when Eclipse is started up.
