Please post your logs on an external site, and link to them here, instead of directly posting. The lines go off the edge of the screen, it's hard to read, and looks really terrible. From what I can see, do you have a folder with question marks (??) in them? If so, rename it to something without any special characters. Special characters in path names can cause unexpected/undesired behavior. If that's not the case, or that doesn't fix it, please properly post your debug.log on an external site, and link to it here.

My guess with the somewhat limited information provided would be that the structure (NOT the feature) needs to be added to any biomes that may border on the custom biome. Adding the structure will allow it to be built there, but not adding the feature will cause it to not begin generating there.

debug.log from your logs folder in the game directory is better than the crashlog, it contains more information. Post it to an external site (github gist is good) and post the link here

Did you really name your world that? If so, you should probably not use funky characters like ^ and (, as a lot of times weird characters in the path can cause strange behavior. It does look like you posted a full log this time, I see stuff erroring out from vanilladeathchest and optifine. It looks like vanilladeathchest came from 9 minecraft, so who knows what it's doing behind the scenes. Delete it right now, and go redownload it from curseforge. If curseforge does not have it, then don't use it. Do the same thing for extraboats, crayfish backpack whatever it is, adventure tools, curious elytra. . . .basically delete ALL of your mods that have -Mod in the filename, and then go redownload from curseforge. Or don't use them, because 9 minecraft is bad. BAD. And of course, Optifine, always try without Optifine.

That looks like a partial log as well. Have you tried it without Optifine? Any performance enhancing mods are hacky, and you should always try without them if you are having issues, as they are very often the cause.

Please post your debug.log from the logs folder in your .minecraft folder. This should give more information on what is wrong. The file may be large, so you might have to post it on an external site and link to it here (github gists are good)

A few tips: You should post your debug.log instead of just the crashlog, the debug.log has more info in it, sometimes the crucial piece needed to figure out the problem Get a github account. Now. (like, go to github.com right now, make an account, then come back to this window and continue) Use that instead of uploading zip files to dropbox. Sooo much better, and more people will look at your code to try and help. Not to mention using git itself for version control is awesome, you don't know what you're missing. My best guess is that you created a json file that is broken, you should check out data generators in McJtys tutorial: https://wiki.mcjty.eu/modding/index.php?title=YouTube-Tutorials *edit: annnd just noticed the modid baseMod has a capital. lol. Anyhow, that doesn't change any of my other advice.

It has a capital B, open the Food class and find the nested Builder class. You should be able to right click on the method name in your own code and go to definition or something like that (I don't use IntelliJ so don't know what they call it, eclipse says "Open Declaration")

Look at the Food.Builder class, it tells you why it is deprecated right in the code.

Just a heads up, it probably took so long because you included some folders that were not necessary for a buildable repo. You do not need: .gradle folder .idea folder build folder

Your debug.log will tell you exactly why. Please post it

If you kept reading the posts after the original poster, you would see that really old versions are no longer supported. Please update to a modern version if you wish to receive support. More information on supported versions can be found in the LTS link at the top of every page.

No, however whoever is running the server will need to allow and forward the port the server using through their router in order to make it visible to the outside world, and the remote player would need to know the public IP address (not the 192.168.x.x IP of the internal computer) of the host in order to connect.

What does your main mod class look like?

Can you cite a source on that? I'm almost positive I've seen it advised to do stuff in CommonSetup (using DeferredWorkQueue for thread safety which I forgot to mention above) *edit: also, was just looking at Tropicraft, and it does the ore generation setup in FLMCommonSetupEvent (https://github.com/Tropicraft/Tropicraft/blob/17bcace66cbcbe1535e52a50bab48ccdd533ab9a/src/main/java/net/tropicraft/Tropicraft.java#L125) Thanks!

Most of the changes from 1.14 -> 1.15 were rendering I believe. https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e has info on some of the 1.15 changes

Looks like you're trying to setup ore generation in your constructor, which is before any registry stuff has happened, so your ore doesn't exist. Try moving ore generation setup into FMLCommonSetupEvent Also, you should update to 1.15.2, as 1.14.4 is going to be out of support once there is a RB for 1.16.x.

Double check your system environment variables for I think it's JAVA_OPTS or something like that that is setting -Xmx2G

If you're trying to follow a tutorial, use these: https://wiki.mcjty.eu/modding/index.php?title=YouTube-Tutorials They're the most up to date, and best laid out, and are the ones suggested if you ask about tutorials on the forge discord. McJty is also one of the few tutorial makers that doesn't force you to sit there and watch a video, as he has a text based version to go with them.

Positive, any perceived order after Blocks -> Items could change at any time. I've seen people that know what they're talking about (including Lex) say it a million times.

Just to make sure this fact is known, the only order of registration that you can rely on is Blocks -> Items -> Everything else, in a non-specified order. The order of any other registrations besides blocks and items is subject to change, even between different runs.

There are no updates for the 1.16.1 mappings currently. It is being worked on.

Have you looked at the DefaultBiomeFeatures class? It is in the net.minecraft.world.biome package. It contains methods such as addForestTrees and addOakAndSpruceTrees that you can look at to see how vanilla generates trees.

The official documentation is not meant to be a tutorial. It's more of a getting started and concepts guide. If you click the "Youtube tutorial step by step" link on that page you linked to, you'll get the txt version of the tutorials.

Can you run the eclipse gradle task?
