[1.14.4] Gradle cannot download/resolve MCP mappings

[Arcaeca 0]

So I just today realized the source in my Eclipse project is actually supposed to be human-readable and not 99% methods with the SRG names like func_177716_a, so I looked back in the build.gradle that the project was generated from, aaaaaaand whoops, I had accidentally commented out the MCP mappings line entirely, which probably explains that. So now I made a new folder in the Eclipse workspace folder and am trying to build the project clean from scratch again, but gradlew genEclipseRuns keeps terminating in under 30 seconds because it keeps failing to resolve the MCP mappings.

It's not working with stable 58:

minecraft {
	...	
	mappings = 'stable_58'
	...
}

Terminal output: https://pastebin.com/zvUMcjLN

And it's not working with the most recent 1.14.4 snapshot:

minecraft {
	...
	mappings = 'snapshot_20200119'
	...
}

Terminal output: https://pastebin.com/gkHe5vdw

So... if it can't download the stable release... and it can't download the snapshot... what does that leave me with if I'm modding for 1.14.4?

(This is my first time trying to make a mod by the way, so if other versions of stable/snapshot work for 1.14.4 I am not as yet aware of it)

build.gradle attached just in case.

If you look at the line that is commented out:

Quote

// mappings channel: 'snapshot', version: '20190719-1.14.3'

 It shows you the format to use.

Comment out/delete the line(s) you added, uncomment that one, and just change the version to a newer version.

The last 1.14.4 version I see is mcp_snapshot-20200119-1.14.4

So change the "version: '20190719-1.14.3'" to "version: '20200119-1.14.4'" (but leave the channel: 'snapshot' there) and rerun your setup tasks, and you should be good to go.
