That log does not appear to be complete, as far as I can see it does not even show the server completing startup nor accepting any client connections.

I think you might be in the wrong place looking for help with this. Or you posted the wrong crash? Does not appear to be any forge being used here, and it's a snapshot version of Minecraft, not a release version.

Make sure you scan through the entire log, you will (usually) eventually find something that makes some kind of sense.

Not really sure, but I think the minecraft forums have a section for modding, you could see if they support old versions there.

The @Override notation is used when overriding a method defined in a parent class, to either replace or add additional functionality.

Please post logs as described in the EAQ, unfortunately pictures (even when they have error messages) do not have enough information to figure out what the problem is.

1.12 is no longer supported on these forums due to age, regardless of which mods are or are not available. Please update to a modern version to receive support here. Moderators will close topics opened for old versions. Please see the LTS link at the top of every page for more information.

Did you fix it? I downloaded your github, set it up, and the mystery block and bomb are in my creative tab and seem to be working.

The setups from 1.12 -> 1.15 are really different. For 1.15, you can just import the build.gradle as an existing gradle project, or if you want to set it up from the commandline, the tasks are eclipse and genEclipseRuns

Only if you update to a modern version, there is just not enough resources to support old versions. Once a moderator sees this thread, it will get locked. If you can not/will not update, you will have to look for help elsewhere.

You should make a github repository for your code/project, much easier for people to read from there If you must post here, you should use spoiler tags (the eyeball button in the forum editor) so there isn't a huge wall of text. In order to provide more help, you should always post logs as described in the EAQ (also using spoiler tags). If the log is too long, use a github gist or another service to host the log, and post the link here.
