gradlew setupDecompWorkspace Error

[Torchit671]

I am new to Forge and I am attempting to set it up in order to start creating mods. However, I encountered an error that told me it could not reserve enough space for an object heap, as well as something concerning daemon.

• Solutions I've tried:
  • I found that this may be related to ram, so I attempted boosting my ram with a thumbdrive to no success.
  • Editing the gradle.properties file
  • Deleting everything and creating it again.

I was ready to give up, but then I found out that forge for 1.7.2 was working just fine using the same steps, and that I could probably make 1.7.2 mods. 

I am bewildered and in dire need of help. Thank you for your time.

 

Here is what I got from stacktrace:

For some reason, it only worked for me when I tried in a new folder, but you have a different error, so it may not work for you

What IDE are you using - there's an alternative method if you're using IntelliJ

[Torchit671]

Thank you for your input, I am using eclipse

[Draco18s]

To me it looks like you need to allocate more RAM to the decompile process or you may need more RAM in your machine. (it looks like it gave up after trying to allocate more than ~3GB).

 

You can also try telling it to use less RAM (in the event that you don't have 3GB available in your machine and can't add any: e.g. a 32 bit OS).

Thank you very much for your help! I changed gradle.properties and the problem has been resolved. I still get an error when decompiling Mc, but I'm sure I just need to upgrade to Windows 64 bit to unlock my potential ram. 

[Draco18s]

Yeah, setting up on a 32 bit OS is dicey at best.

I managed it once having to continuously tweak the ram allocation up and down by increments until it worked (there's two different errors: one says it couldn't allocate the RAM, and you go down in MB, the other said it ran out of heap and you go up in MB).
