I understand that this is a dev version. Just wanted to let you know.

I installed 2321 successfully (had to uncheck the Mercurius option first)

When I try to launch, it fails to download file asm-all-5.1.jar
I see this message in the launcher: 

Couldn't get hash for org/ow2/asm/asm-all/5.1/asm-all-5.1.jar from https://libraries.minecraft.net/org/ow2/asm/asm-all/5.1/asm-all-5.1.jar.sha1: HTTP 404: Not Found

I have tried this in the Mojang launcher, and also in MultiMC.

go to: https://mvnrepository.com/artifact/org.ow2.asm/asm-all/5.1

Get the file.

go to your ".minecraft\libraries\org\asm\asm-all"   Folder

create a new folder and name it 5.1

paste the .jar file

 

remove all current mods from the mods folder.

 

Launch minecraft forge beta

 

Worked for me.

fixed filepath

Tried that, and unfortunately game still tries to download that.

When I close the launcher and run it again, it shows the following message:

 

"The version you are trying to play inherits properties from an unknown version".

 

Any way I can fix that?

 

>Also, I tried deleting the forge profile, even installed 2320 version to check if problem persists. Sadly, it's still here. I've also launched 1.12 vanilla before.

That's cool. I appreciate it, and will wait until a dev release that mentions this in the changelog before trying again. 

Aight, will do.

 

Probably I shouldn't ask about that, but when can we expect a stable release?

Solved, put that jar in the folder

"%appdata%\.minecraft\libraries\org\ow2\asm\asm-all\5.1"

Absolutely! Thank you. I didn't think it was going to be that simple. I imagined this was the first of many files that could not be downloaded, but you are quite correct, and now I have it running.

Also, you still owe me money.

There was no context on the previous person's post, I got the exact same log message when I tried:

It doesn't seem that that solution works, but it's still on the same topic as OP's issue.

All of this discussion is now superseded. Version 2322 is out now, and specifically mentions fixing this problem in the changelog.

I have run it and it does indeed work. This thread can now be closed.
