First pass at an avaje inject module

helps alleviate #3415

@SentryMan, this does not work, at least for me. This is the error:

where my DataCache class is declared as singleton with constructor like this

    @Inject
    public DataCache(Jdbi jdbi, Config config) {
       ......
    }

My proposal above works fine, though.

Should I prepare some example code for experiments?

you mean with the @InjectModule(requires={String.class}) thing? For that, you only need to say String.class once and it'll take care of things. I'll need to make a note of that in the docs.

Yes, this way it works, thanks.

3. Using this module needs a special maven/gradle plugin and setup for Avaje code generation

This should only be required if you are running on the module-path and also happen to have custom avaje autoconfig libraries. But yeah it is what it is
