Minecraft plugin returns error

So, i want to make a simple plugin, that prints some text into console, and after build, i get error [20:16:08 ERROR]: Error occurred while enabling LogConsole v1.0 (Is it up to date?) java.lang.NullPointerException: Cannot invoke "org.bukkit.command.PluginCommand.setExecutor(org.bukkit.command.CommandExecutor)" because the return value of "ru.mrksbgg.logConsole.LogConsole.getCommand(String)" is null...

Blocking/Preventing certain GIT actions on repositories

I've implemented a combination of Git Hooks both client side and server side to prevent the merging between specific branches. As of right now, the server side pre-receive hook is able to prevent the push to remote, but the commits from the merge command is still staged locally, thus having to reset HEAD~n. I am looking for a cleaner way to prevent

git merge x

git merge x

if I am invoking that command from

branch y

branch y

and only

branch y

branch y

, to be staged locally. Can the client side pre-commit hook somehow check for this? Any suggestions?...

VS Code Setting

This may seem silly but it's been really annoying to deal with for a while now. Whenever I use overloaded methods (for example the println or the add method on ArrayList) that can have either different type or number of arguments, I get this box (see image) that lets me arrow between different versions. Does anyone know how to remove this? It takes priority on up/down arrow keys which makes moving between lines of code very frustrating since I frequently use the arrow keys to navigate my code. L...

How to get built jar during test-time (JUnit)

I'm making an integration testing framework for Minecraft plugins which uses JUnit. My plan is to send a built plugin file during test-time to a docker container, which in term runs a server with that specific plugin file, which will be loaded using the servers class loader. This file should not include test resources The problem I'm facing is that there's large differences in buildscripts for projects; it would not be feasible to just run something like ./gradlew build and retrieve the file from it's directory, as there's also maven, and multimodule projects and much more that I don't know about. What is the least painful approach to generate or fetch this file?...

Help me with spring JDBC

Hello, I'm using spring data JDBC to manage two entities, but I am getting a rather strange exception when testing the UserRepository. Spring is trying to map the "users_key" attribute of the "expense" table, but this attribute is nonexistent. I'm sure the core problem is in the mapping of the "expense" attribute of the User entity, because when I annotate the attribute as @Transient, the exception doesn't occur. Below are the images of the entities, the SQL script to generate the tables, the test code, the repository and the stack trace...
