I’ve written a thorough presentation of the issue here

> <https://stackoverflow.com/questions/64872130/how-to-configure-a-plugin-with-custom-sourceset-extension-in-kotlin-dsl>

To summarize I want to use a gradle groovy plugin i android, which extends sourceSet. However I cannot get that sourceSet extension from Android as its an AndroidSourceSet.

I tried various tricks.

I cannot get `dynamic-groovy-plugin` to work at all, gradle 6.7.1 complains if I add that plugin, as mentioned in [Kotlin Dsl Primer](https://docs.gradle.org/current/userguide/kotlin_dsl.html#sec:kotlin-dsl_plugin). It could be a general interesting method to fix such troublesome cases.

Also I couldn’t seem to get extensions via the `sourceSet.withGroovyBuilder `, though I’m not sure that’s the intended purpose.

I couldn’t figure out how to get an SourceSet from AndroidSourceSet.

I kind of found an answer here: [How to access `extensions` on any DSL object statically?](https://discuss.gradle.org/t/how-to-access-extensions-on-any-dsl-object-statically/28867/1)

It shows how to access the groovy extensions for any object, which was the biggest part of my problem.
