Hi everyone, I am working on this issue #2578 (Hacktoberfest 2022). I was working on the ceiling function, in Numeric section. I've hit a roadblock can't understand the following error. Can someone guide me, what I am missing?

Hi Sourav, Probably you need to register your functions in

core/src/main/java/module-info.java

and

core/src/main/resources/META-INF/services/io.questdb.griffin.FunctionFactory

. Check how it's done in this PR: https://github.com/questdb/questdb/pull/2579/files

Thanks Andrei, it worked.

fwiw: I had exactly the same problem when working on my very first QuestDB function: I added the factory to

META-INF/services/io.questdb.griffin.FunctionFactory

, but I didnt know about

module-info.java

It was driving my crazy, debugging ServiceLoader, classloaders & friends! :)
