Personally I don’t like people trying to do automation client-side, even if they say the server allows it.
It would be too easy to repurpose such a mod to steal items on servers, if such automation is allowed then the server owner should consider a sponge plugin or something.
Did you test the pack as you added mods or did you add them all in one go?
Morecommands is at least slightly broken and at least slightly poorly written.
I have no idea why the installer is having issues connecting to AWS...
Try downloading the server directly, this is a direct link to where the installer is supposed to get the server, do not rename it.
That's the stacktrace of the error, helpful but I'd rather get all the details I can, please post the installer log.
The log is a file with the same name as the installer, but with .log on the end
Dunno about Gradle, but ForgeGradle won’t work on Java 11.
If you want to work on or play Forge 1.12 or earlier, you need Java 8.
If you’re only interested in 1.13.2, you can get away with using Java 10 OR 8.
Yes, but I don't see any major issues there.
A small issue I see is you have 8G of RAM allocated while running just a single mod, unless you have a beast of a computer I would recommend lowering that unless mods need that much.
What you posted first looks like the latest.log, it's like debug.log but has less info in it.
What you posted second is a crash report, which is usually helpful but in this case we require more info than it provides.
