I have:
Eclipse SDK, Version 3.2.1, build id: M20060921-0945
MyEclipse is: version 5.1.0 GA, build id: 20061111-5.1.0-GA

My machine is running Windows XP with 1.5Gb RAM.

I’m running a build.xml, and the build keeps failing with these messages:
[javac] The system is out of resources.
[javac] Consult the following stack trace for details.
[javac] java.lang.OutOfMemoryError: Java heap space

I’ve modified eclipse.ini so that it contains this:

-vmargs
-Xms256m
-Xmx768m
-XX:PermSize=64M
-XX:MaxPermSize=128M

I’ve also tried starting Eclipse with a batch file containing this:

D:\eclipse\eclipse.exe -vm C:\jdk1.5.0_09\bin\java.exe -vmargs -Xms512m -Xmx1024m -Xss2m -XX:MaxPermSize=256m

Even when I have no other applications open, the build fails as above.

Any suggestions?

Thanks in advance-

If you are running the build.xml in an external tools launch configuration, then your build.xml is running in a separate jvm instance. So increasing the -Xmx settings on the jvm that is running eclipse will not affect your build.xml script.

– Go into Run > External Tools > External Tools…
– Select your build.xml launch configuration
– Switch to the jre tab
– under vm args add “-Xmx256M -XX:MaxPermSize=128M”

Then relaunch the build.xml. That should do the trick.
