Please provide your debug.log (More info in the EAQ thread and my signature)

That's really too vague to be of any help, logs please.

Decocraft requires PTRLib, this is written in BIG letters on the CurseForge page but I don't know if the same message is on the 9Minecraft page, and I doubt the admin at 9Minecraft really cares.

Don't use 9Minecraft. Please read my signature for information about why.

That's not the mod causing this issue, where are you getting your mods?

What's in that folder?

Each task has criteria for skipping, usually it will skip tasks that have already been done and had their output cached, so you're not downloading the game assets or running the same decomp process every time when nothing has changed

You are running an MCreator mod, ditch it and suggest the mod creator learn Java and do it properly. Edit: Yes this is mod is causing your issue.

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

You are running a 32-Bit JDK, you should be using a 64-Bit JDK.

Why did you edit this value?

Are you still having this issue? Try updating to the most recent MDK before responding.

I'm not sure what you're trying to do here and your code has been taken down for some reason. If you want/have to share code please do so via a GitHub repository.

This is just as vague as "load up my mod".

The game is running out of Memory, give it more.

It seems a bit sketchy, is the laptop yours, borrowed, or does it have parental controls or some such turned on?

Why would you not have access to cmd or terminal on your machine?

Don't do this. What exactly are you trying to skip here? Do you want to skip the decomp and deobf time or are you going somewhere without internet? The Forge MDK uses a Gradle wrapper (Batch and Shell scripts combined with a Jar file, allowing Gradle to bootstrap itself on any system with a JDK installed). As long as you have a JDK installed that the included Gradle Wrapper can use (along with an internet connection to allow Forge to fetch all the dependencies), you'll be fine.

Can you please show screenshots of your launcher and your mods folder, as well as pastebin your debug.log

If you put your mod source on GitHub using the gitignore supplied in the MDK the only requirement on the other side is a JDK and some time for the sources to be re-generated, and your IDE of choice, obviously.
