Version of the mod: 1.3.1, 1.3.0, 1.2.3, 1.2.2, 1.2.1
What you were doing (ingame) when the issue occurred?: N/A
What is the issue?: The source code on github does not compile, with two main consequences. First, this means that Backrooms cannot be used as a dependency for other mods without cumbersome and unreliable workarounds. Second, it means that developers who wish to fork Backrooms cannot do so.
What other mods do you have installed?: N/A
Log/Crash report?
When the repository is forked it fails to compile, reporting the following:
"Build file 'C:\Users\dvdtr\Documents\Minecraft Mods.3rd Party Mods\Backrooms\build.gradle' line: 2

Plugin [id: 'fabric-loom', version: '0.4-SNAPSHOT'] was not found in any of the following sources:

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights."

Attempting to use the repository as a dependency also fails, with the error report here:
https://jitpack.io/com/github/LudoCrypt/Backrooms/1.3.1/build.log

Any additional information?: I believe the error stems from several important files that are excluded from the repository. These include at least gradlew and gradlew.bat.
