If you remove that mod, does it still crash? If so, post new crashlog plz

I would say that mrcrayfish furniture mod is trying to access client classes from the dedicated server, probably need to remove it/report it to the mod author.

Your ClientProxy is not derived from CommonProxy, so it cannot be stored in that field, and you also do not tell the @SidedProxy which class to use as the ClientProxy.

You should show what you tried, people are more likely to help debug some already written code than to write some up for you

That log shows 3G ram for minecraft, were you trying a lower setting to see if it helped?

I see exceptions being thrown from applied energistics, have you tried it without that mod? If it works after removing, report the problem to the mod author.

After you've run gradlew build, your jar file will be found in the build/libs directory in your project directory.

Unfortunately, 1.7.10 is so old, it is no longer supported on these forums. You will need to update to a more recent version to receive support.

Correct. After you do that, reinstall forge and see if it works.

I searched these forums for "unknown version" (including the quotes), and it seems you need to run vanilla 1.12.2, then uninstall/reinstall forge. Give that a try, hope it works!

If you don't have logs at least post a screenshot of the crash or something. And I've /never/ seen an error saying "has things from other versions". . .if you're going to quote an error without a log or screenshot, make sure you quote it 100% accurately. Also, where did you download forge from? Hopefully it was files.minecraftforge.net We have nothing to go on, so there's no way anyone could help you with just this information!

This shows a max of only 1G allocated. Post a log where it crashes where you allocate 4G.

1.7.10 is really really old, and no longer supported on these forums. If you want support here, you will have to update to a more recent version.

I would go right for 1.12.2, latest and greatest!

1.7.10 is very old and no longer supported on these forums. You will need to update to a more recent version for support.

I searched the forums for "libraries failed to download", and this is the first result (after your post that is) http://www.minecraftforge.net/forum/topic/65042-these-libraries-failed-too-download/?tab=comments#comment-308666 A possible solution is presented there.

Remove xray mod from the server and try again, looks like it's trying to read client stuff, which doesn't exist on the server.

Remove all torohealthmod files from your server and try again.

Looks like you're registering yugioh_cardback_item twice. I'm guessing copy & paste are to blame.

1.7.10 is no longer supported on these forums, due to it being ancient. You will need to update to receive support here.

These logs are from 2 different versions of minecraft. The first one is for 1.10.2, second is for 1.8.9 Also the second log states: Server brand: BungeeCord (Hypixel) <- vanilla

You must use Java 8, not 9 or 10. If you have 9 or 10 installed alongside 8, you will need to specify the full path to the java.exe when launching (easier to remove 9 and/or 10 if you don't have a specific need for them)
