I agree with the others who said that there is no simple way to distribute these settings.

For Eclipse: ask your colleagues to set the following:

• Windows Preferences / Java / Installed JREs:
• Select the proper JRE/JDK (or do it for all of them)
• Edit
• Default VM arguments: -Xmx1024m
• Finish, OK.

After that all test will run with -Xmx1024m but unfortunately you have set it in every Eclipse installation. Maybe you could create a custom Eclipse package which contains this setting and give it to you co-workers.

The following working process also could help: If the IDE cannot run a test the developer should check that Maven could run this test or not.

• If Maven could run it the cause of the failure usually is the settings of the developer's IDE. The developer should check these settings.
• If Maven also could not run the test the developer knows that the cause of the failure is not the IDE, so he/she could use the IDE to debug the test.
