It seems like since after 0.20.0-2, Fiber stopped to compile normally, I found this out by seeing that there was no 0.21.0 in the maven (despite the wiki and README telling to use it), then I tried to grab it from Jitpack as a last resort, it didn't work. I compiled it myself just to make sure. Yep, it still didn't compile. (I manually changed Gradle to 6.3 in order to make compiling possible for my JDK, however, it shouldn't matter)
