This may be a repetitive question for you, but, have you set your ANT_OPTS system variable? Follow the directions on this wiki article if you haven't, and that should solve your out of memory compiling problems:

Hi There,

I have searched the forum for the same and unable to mark it properly

[javac] The system is out of resources.
[javac] Consult the following stack trace for details.
[javac] java.lang.OutOfMemoryError: Java heap space

BUILD FAILED

Thank You!

I was getting errors when using the jikes compiler. So I switched to Sun's compiler and was successful, though it took a while to compile. I changed the following in build.properties:

javac.compiler=modern
javac.fork=true

Without the fork=true I too got the OutOfMemoryError.

Hello,
I still have no answer on my problem.
May be it is because I use javac instead of jikes? or is it my machine that is not enough strong?

Thanks. But I've already take some time on different posts on the forum and on the LEP. But I could not find the same problem.

I've tried to :
- configure my JVM parameters (maximum memory : 512Mo)
- to launch 2 "start" (ant clean start start build-ext)

but none could resolve my problem.

Hello,
I try to compile LR 4.2.0 via ANT on Eclipse.
I followed the instruction at this page http://content.liferay.com/4.0.0/docs/quickstart/ch04s01.html
But when I want to do this : ant clean start build-ext I got this error on ANT console, after launching "start"

build-common-java.compile:
    [javac] Compiling 1695 source files to D:\workspace\projetLR\liferay\portal\portal-ejb\classes
    [javac] Since fork is false, ignoring memoryMaximumSize setting.
    [javac] The system is out of resources.
    [javac] Consult the following stack trace for details.
