Quittime

I booted up an Ubuntu virtual machine just to see if I would get the same error and it worked! I won't mark this as solved just yet because using a virtual machine with a completely different operating system isn't really a solution. I will still be open to suggestions as well because virtual machines are really slow. I also won't be changing my system's OS to Ubuntu either because that's too much of a commitment and Windows 10 is best for gaming. Anyways, thanks to everyone for the comments. I will try to create some cool mods in Ubuntu, so be prepared for more from me!

I think that command was introduced in forge for 1.13. In 1.12, like you kind of said, setupDecompWorkspace is used instead.

Just the same old crash: https://pastebin.com/jvVAZC3C Running that was successful but it just threw out the same old error. I even tried using different forge versions.

UPDATE: I've discovered that in my crashes contain this line: OpenGL: ~~ERROR~~ RuntimeException: No OpenGL context found in the current thread. and I will like to address a few things that make my problem different from other people that get this error. I can run Minecraft and Forge perfectly fine from the launcher, or even other launchers like the technic launcher, unlike most people. My GPU isn't old and its drivers are updated. I have also tried everything on this since a lot of people on other forums recommend it: http://hopper.minecraft.net/help/pixel-format-not-accelerated/ but nothing applies to me. Remember that I'm still open to suggestions and your help is appreciated. I will continue to search and if I find a solution, I will post it here. Thank you!

Yes. I can run the exact version I am trying to develop for outside of Eclipse through the Minecraft launcher.

NVIDIA GeForce GTX 1070

Thank you so much for the suggestion. Sadly, I still get a similar crash when I follow the "setting up the development environment" one: https://pastebin.com/0kKxKiWd Edit: This ^ uses the outdated JDK but I re-did it with the latest JDK and it still gives the same crash: https://pastebin.com/UVbJQiu2 If I do manage to get Forge working properly, I will check it out though ?

Alright. I created an oracle account and downloaded the latest JDK I could find for 1.8 and I got the same crash: https://pastebin.com/ubszwM66 Edit: also I changed the JAVA_HOME environment variable to the new JDK version as well.

I am following this tutorial here: https://suppergerrie2.com/minecraft-1-12-modding-with-forge-1-getting-started/ Also, doesn't the Forge Gradle use java 1.8? Also, from all I can see, you need an oracle account to download java 1.8 since it isn't supported anymore.

Hello! I am a new mod developer so this is my first attempt at creating a mod. I've set up the project just fine according to the tutorials I'm following. I've run "gradlew.bat setupDecompWorkspace" and "gradlew.bat eclipse" and those worked just fine without any errors. Next, I set my eclipse workspace to the "eclipse" folder inside of my project folder. I am basically setting everything up how you are supposed to. After that, I pressed the green play button in eclipse that is supposed to run Forge with my mod, but it just gives this crash instead: https://pastebin.com/dGFJ9Dni The only code in my project is just the Hello World example mod code it gives you when you first create a mod. I haven't changed anything. According to the tutorials I'm looking at, this should run fine. What is my problem? Also, I don't know if this helps, but the JAVA_HOME environment variable is set to C:\Program Files\Java\jdk1.8.0_161 and my PATH variable is set to %JAVA_HOME%\bin And just to rule the last thing out, both Minecraft and Forge work just fine when running them from the launcher (not from eclipse). Anyways, I really want to get into modding and this wasn't the warm welcome from Forge I was expecting. Any help is appreciated!
