is mecca no longer used?

I cloned the project and found that it won't compile with dmd 2.105.0 so decided to try building with a wide range of dmd releases:

2.076.1	src/mecca/platform/os/linux/time.d(75): Assertion failure: hangDetectorTimerId is null

is this project no longer maintained/used?

No, unfortunately it's not maintained. Weka stopped maintaining it so it was moved to dlang-community in the hope it would get maintained there, but unfortunately not.
