So I tried setting up Forge 1.7.2 but when I ran the setupDecompWorkspace, I got the outOfMemory-Error because of heapspace. To fix this, I changed line 75 of gradlew.bat to this:

 

"%JAVA_EXE%" -Xmx512m %DEFAULT_JVM_OPTS% %JAVA_OPTS% %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" -classpath "%CLASSPATH%" org.gradle.wrapper.GradleWrapperMain %CMD_LINE_ARGS%

 

after that I didn't get out of memory errors anymore, but now I'm stuck with this error:

I've tried updating Java as well as using different 1.7.2 builds of Forge. When I cut the change in the gradlew.bat I get the outOfMemory Error instead. I'm kind of at a loss right now.

Update your jdk, there are certain versions that are broken, IIRC it's like 1.6.0_23 or something.

Yeah, as a short term fix I went to java 8, even though for comforts sake I want to mod with java 6. I'll find a working version of Java 6 if I have more time on hand.

It works with java 8 btw.

On another note, why don't you have the 512 mb RAM allocation (or however much is needed) done for everyone? I kind of know what I'm doing, so I could easily fix it, but for quite some people just adding the line I did to gradlew.bat would help I think.

Because I expect modders to not be retarded. And most systems default to enough.
