Can't run mod from Eclipse

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!

You should update your JDK.

Also there's no need to set your eclipse workspace inside the mod since Eclipse has added/improved their Gradle integration.

 

Can I ask what particular tutorial you're following?

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

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.

This is true, but oracle accounts are free. So make one.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

I immediately don't like that tutorial.

Try this one: https://cubicoder.github.io/tutorials/1-12-2/tutorials/

Thank you so much for the suggestion. Sadly, I still get a similar crash when I follow the "setting up the development environment" one:

Edit: This ^ uses the outdated JDK but I re-did it with the latest JDK and it still gives the same crash:

If I do manage to get Forge working properly, I will check it out though ?

Are you able to run the game outside of a dev environment?

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!

I don't know if this will help or not, but when I had this issue on the most recent version: (after they removed setupdecompworkspace)

 

I had to run a command:

gradlew genEclipseRuns

 

To fix my Eclipse, i had to run these commands in this order:

gradlew clean

gradlew genEclipseRuns

gradlew eclipse

 

it was critical to run "genEclipseRuns" before "eclipse."

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

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!
