Hello, Is it possible to have a KMM project nested in another one? Like create a KMM library, and the project includes a test app build with KMM as well.

Yes, you can create multiple-project builds with Gradle: https://docs.gradle.org/current/userguide/multi_project_builds.html#multi_project_builds Here's an example of one if you prefer to learn by example: https://gitlab.com/arcachon-ville/formulaide

Thanks for your answer! So I cannot go deeper than one level.

You definitely can, sorry if that wasn't precise. Here's another one that goes multiple levels down: https://gitlab.com/braindot/clovis (notice modules

:compose

,

:compose:client

, etc)

Thank you so much for your guidance. I went a little deeper in the doc you gave me, and I think I found what I needed https://docs.gradle.org/current/userguide/structuring_software_products.html

Glad I could help ^^
