Hi could you explain what is happening here? When I checkout the single lib branch, I get an error that reads:
Task with name 'bundleSolidRelease' not found in project ':matterlib'.

if (android.productFlavors.size() > 0) {
    android.libraryVariants.all { variant ->
        if (variant.name.toLowerCase().contains("debug")) {
            return
        }

        def bundleTask = tasks["bundle${variant.name.capitalize()}"]

        artifacts {
            archives(bundleTask.archivePath) {
                classifier variant.flavorName
                builtBy bundleTask
                name = project.name
            }
        }
    }
}

Can't see what I am doing wrong really this is all pretty confusing, I get the same error in my project 😄 I would like to publish build variants for my library.

When we build the library without specifying the product flavor, it correctly builds the library module specified using 'defaultPublishConfig' (AAR file along all of the transitive dependencies specified in that module) so that the consumer of the library do not require to include the dependencies of the library module. This works fine.
implementation "com.github.mirceanis.multi-flavor-lib-demo:matterlib:$library_version"

But, when we try to build a particular product flavor by using
implementation "com.github.mirceanis:multi-flavor-lib-demo:$library_version:solid@aar"
It does not include the transitive dependencies of the library module and the consumer of the library gets runtime exceptions stating that the class files could not be found. So when we build the product flavor, how to include all of the dependencies specified inside that library so that the consumer of the library do not require to include the dependencies themselves?

demo a way to package sources properly so they are easily linkable in IDE
