Seems like an issue while generating fake overrides (which, I think, are equals, hashcode, toString, etc) related to a class having 1 type parameter yet receiving 2 type arguments.

[Dave]

many thanks....I can probably find the problem from that...I did just remove a type argument ;-)

[Youssef Shoaib [MOD]]

Might also just be some outdated incremental compilation information, so I'd suggest trying a gradle clean first and then build and see if you experience the same error

[Dave]

I tried that first 😉

[Dave]

problem was an outdataed library that used a different api....thanks for the ideas that helped me track down the issue.
Some better error messages would help 😉

[Youssef Shoaib [MOD]]

It's kinda difficult for the compiler to track down dependency issues like that. It's left up to Gradle and other such tools to determine those conflicts
