Defining Consumer from Groovy build.gradle

Thanks again James. I really appreciate your help. This is not a simple series of questions, but your answers are really helpful.

But I agree with you 100% that that is the DSL I like conceptually.

I had not thought of extending the extension (I already have a main DSL extension object) to include these profiles and dynamically adding discovered ones. This would be a “named container” I assume?

So my existing DSL extension looks like, e.g.:

databases {
    defaultProfile = 'derby'

    profileDirectory 'custom-databases'

    ...
}

Like I said, I conceptually like the idea of adding the profiles to this DSL:

databases {
    defaultProfile = 'derby'

    profileDirectory 'custom-databases'

    profiles {
        ...
    }

    ...
}

I’m just not sure about the specifics of:

find fragments and add them to the databaseProfiles extension separately

I’m sure I am missing something.

So I assume you mean is something like:

public class DslExtension {
    private final Project project;

    private String defaultProfile = "h2";
    private final List<File> profileDirectories = new ArrayList<>();
    ...
    /** 
     * Think of Profile as GradleProfileFragment.  ATM we allow 2 distinct ways to define a profile:
     *    1) via a Gradle fragment
     *    2) via a dir with properties file and jdbc jars
    *
    * But for making this easier... let's assume there is just one way - via a Gradle fragment and
    * that Profile == GradleProfileFragment
    */
    NamedDomainObjectContainer<Profile> profiles;
}

So when Gradle sees, e.g.

databases {
    ...
    profiles {
        h2 {...}
        derby {...}
    }
}

it will automatically create 2 profiles in the DslExtension#profiles NamedDomainObjectContainer named h2 and derby. But I am still unsure of how to process the Gradle fragment files I discover.

Is the idea that the Gradle fragment file would specify that full “path”? I.e.:

profile.gradle
---------------
databases {
    profiles {
        oracle {...}
    }
}

That’s not ideal, but if it works I can live with that.

Am I understanding you correctly?
