Reflection

I have code which uses the following dependency:

implementation("org.reflections:reflections:0.10.2")

It works fine in the IDE.  However, if I generate a JAR, the necessary code is not included in the JAR (I use a number of other library files, and all of those seem to be there, though).

I have tried adding the dependency to the artifact details manually, which does indeed sort out that problem … but then it simply turns out that something else is missing.

Does anyone know what's going on and how I can fix it?

Thanks.
