Downloaded the source (the latest commit is 2fb1d28) and tried to build it.

./gradlew build

Don't know why but

Tried deleting and unzipping it again and nothing

Seems like Java is complaining about gradle-wrapper.properties being a directory.

Try cloning/downloading it again or, if you just want a build from the latest commit, you can instead use the build provided by Github Actions for that commit (which isn't failing, suggesting it to be an issue with your setup).

For support it would be better to join the discord instead of the issue tracker though.

This seems like a problem with your environment rather than the mod itself. You can get a build of the latest commit from Github Actions - which did build successfully.

Seems like it's something wrong with PeaZip.
