I'd recommend you take a look at the StopModReposts project: http://stopmodreposts.org/ Disclaimer: This is my own personal recommendation and is not in any way a recommendation from Forge.

I do not recommend downloading the libraries manually, try this solution instead:

Do not download libraries manually, try the solution suggested here:

What version of Java do you have installed? Forge requires Java 8, not 9.

You should also STRONGLY consider upgrading.

I'm afraid this isn't the place to ask for support with PO2, I would suggest OG_Arist0tle's Discord as the best place to ask, as he's one of the pack devs, but I CANNOT GUARANTEE SUPPORT. Please note that 1.7.10 is also no longer supported on this forum.

Versions that old aren't supported on this forum. Please update to receive support.

Check that the package and class exist and are spelled correctly.

Would you mind posting your BlockBase class or possibly putting your mod on github and linking it? Took me too long to boot up my own IDE and notice the signature disparity

Please post full logs as described in the Rules/EAQ thread.

From the Rules/EAQ Thread, to have a better chance of helping you your post will need to include: Below is a list of things which you MUST include in your post. Be sure to include the entire logs/fml-{client/server}-latest.log found in your .minecraft folder / server root folder. Not including the log in no way helps us to help you and has a small chance of getting you banned. State what research you have already done (You should have done some, this forum is only for well-researched bugs!). Use the spoilers to enclose stack traces and other long information: Do not attach your logs to your post or use file-uploading services like Dropbox. Use Pastebin or Github Gists. In general give as much information as you can. "It does not work", "I get a black Screen", etc. in no way helps us to help you and will only cause you to get in trouble.

[17:35:27] [main/ERROR] [net.minecraft.init.Bootstrap]: Errors with built-in recipes! Reinstall the instance?

That post looks boilerplate I know, but it's there in the rules thread for a reason. If you read the last bullet in the post there's not much we can do to help you if we don't have any idea what's going on behind the scenes, which is why almost anyone on the forums will ask you for a log.

Have you tried the solution suggested in this post?

Do you know what version of Java you have installed?

Try removing spawnercraft

Are you launching the server through a batch file with arguments or just double clicking the jar?

It tells you in the log, there's 3 mods that you have installed twice net.minecraftforge.fml.common.DuplicateModsFoundException: Duplicate Mods: brandonscore : C:\Users\damia\OneDrive\Desktop\server\mods\BrandonsCore-1.12-2.4.0.152-universal (1).jar brandonscore : C:\Users\damia\OneDrive\Desktop\server\mods\BrandonsCore-1.12-2.4.0.152-universal.jar galacticraftcore : C:\Users\damia\OneDrive\Desktop\server\mods\GalacticraftCore-1.12.2-4.0.1.173.jar galacticraftcore : C:\Users\damia\OneDrive\Desktop\server\mods\GalacticraftCore-1.12.2-4.0.1.174.jar galacticraftplanets : C:\Users\damia\OneDrive\Desktop\server\mods\Galacticraft-Planets-1.12.2-4.0.1.174.jar galacticraftplanets : C:\Users\damia\OneDrive\Desktop\server\mods\Galacticraft-Planets-1.12.2-4.0.1.169.jar

You want to put your mods in the mods folder directly, I believe the 1.12.2 folder is for jar mods. I had theorised this internally for so long that even without evidence I began to believe it was fact. It is not.

Please read the general guidelines/rules thread and make your own thread, also this thread is from months ago.

Nevermind, I was dumb that's client side code and Spiggot doesn't modify that, more research necessary.
