I am currently working on a datapack and wrote an automated build process in Java to produce a zipped datapack.

When I drag that Java-zipped datapack into the datapack folder of a world, it will load the meta file and provide the description when using /datapack list but nothing from the datapack works, such as recipes or functions.

When I zip the datapack via the windows right-click menu, the datapack is detected and works perfectly fine.

The structure inside the zipped file is the same for both of them and yet, only the self-sipped seems to work.

I have attached:

• the datapack that doesn't work (Java-zipped) (mc_betterpack.zip)
• the datapack that is working (self-zipped) (mc_betterpack working.zip)
• the code that I use to zip the datapack (zip.txt)
• an image that shows that the datapack loads in either cases but won't work in the Java case (loaded datapack.png)
