Fabric isn't supported here, only forge.

Please post your debug log as described in the EAQ. It would also help to see your code in a github repository

You can, but if you have problems, you can not get help here for them. Topics related to outdated versions will be closed/locked by forum moderators.

1.7 and other really old versions are no longer supported on these forums. Please update to a modern version to receive support here. More information on supported versions can be found in the LTS link at the top of every page.

1.12 is old, and with so many versions of Minecraft and Forge, they can not all be supported. More information on supported versions can be found in the LTS link at the top of every page. Asking for help with 1.12 is like asking Microsoft to provide support for Windows Vista. They will tell you that you need to update if you want help.

After you're in downloads, type "dir forge*" (there's a * with no spaces after forge) to make sure it's there. If it is, you want to use java -jar forge-1.15.2-31.1.34-installer.jar cd means "change directory", that's why you got an error trying to cd into the installer.

That right there is probably doing it.

No, that's the crashlog again. The debug log will be in the logs folder, and be named debug.log *edit: noticed the path in your crashlog, so you should be looking for C:\Users\fenix\Twitch\Minecraft\Instances\ModPack 1.15.2\logs\debug.log This is of course provided the twitch launcher isn't being a piece of crap and actually generates one!

Try running the installer from the commandline, and if it fails post the output here.

Please keep support requests to the forums, I do not provide personal support via PM. I am pretty sure tlauncher is a pirated copy of Minecraft, and is not supported by forge in any way. You should buy the game if you want to play it.

The official minecraft forums has a modding section, but I do not know what versions they support, or how good it is, since I don't go there. Other than that the best advice I have is update to a modern version

Please post logs from both server and client, preferably on a hosting site, or if you paste here, make sure to put them in spoiler tags (eyeball button when you are making a msg)

The issue appears to be coming from doggytalents, I would wager that it was built using an older version (probably 1.15.2-31.1.14) of forge than the one you have (you have 1.15.2-31.1.30). If you remove doggytalents and it works, you will either need to wait for an update from the author, or downgrade the version of forge you are using (which could break other mods)

I believe you should be using the gradle wrapper, and not your local gradle installation.

You are running 1.14.4 and have biomes o plenty for 1.15.2.

If you refresh the project in eclipse it should find external changes. Again though, no way for us to know without seeing your project layout for ourselves
