Java memory heap error on running decompile task

[aksource]

From yesterday, I can't run successfully setupDecompWorkspace with gradlew.
I checked gradle.log and I saw the problem was occurred form decompile task.
Then, I ran decompile task with --debug option.
I saw gradle log and found a error log below:

Error occurred during initialization of VM
Could not reserve enough space for object heap

I set DEFAULT_JVM_OPTS of gradlew.bat -Xms512m -Xmx512m.
But, this error was not solved.

I check commits of ForgeGradle and I think this problem is happened from this commit:
bb1e035
because my PC is 32 bit OS and has 3.2GB memory.

JAVA_OPTS on my PC is only set -Dfile.encoding=utf8

What's solution of this problem?

set it to even higher.

I don't think it solve this problem.
I downloaded this repository and changed max heap space from 2G to 512M.
Then I built ForgeGradle in local and ran decompile task successfully.

I know the best solution of this problem is to buy new PC that is 64bit OS and has more than 4GB memory but I can't.

Please erase setMaxHeapSize or replace more customizable one.

I changed it to 512M yesterday, feel free to make a PR to make it customizeable if you want.

I checked it and finished decompile task successfully.
Thanks LexManos.
I don't have an idea to make it customizable.
If I have it, I'll send a PR.
