Hey Shinoow,

It isn't directly a mod problem, but somehow your Maven has stopped to work. Your dl.bintray... maven just returns "403 forbidden" to all requests and your fallback maven hasn't been updated since 2017.

~~Wunst

Right, bintray shut down their maven service at the beginning of last month. I haven't gotten around to migrating yet (planning on hosting it myself, but I haven't really had the time to purchase the hardware and set the thing up).
For now you'll have to go the CurseForge route, as there is some maven component there you can use (or several gradle plugins that simplifies it).

Actually, looking at the fallback maven, it is updated to the latest released artifact (2.0.0-ALPHA-3 was released after bintray went into read-only, so that one is absent). I believe the date the date of the folder is when it was initially created (or something). Also looks like the url has changed.

Thank you very much! I'm gonna try the CurseForge thing.
