Good evening guys = ) Is it possible to have a mpp module without any presets / targets? My motivation to this is that I would like to create a common module without any targets / presets, just source sets, and them, in other modules, add this as a dependency. For example in desktop, mobile or backend modules. So I could use something like:

implementation project(':common')

If I put at least one preset / target it seems to work, but without any preset / target it isn’t working. Do you know if we can change our

build.gradle

to achieve this result?

If you want to consume it from jvm, you neeed jvm preset. Simularly with others platform. But you don't have to have any code in your target sourceSets, only in common

You need to have at least one target, otherwise what do you expect your project to consume as a dependency? It has to be compiled first. And then according to your metadata the proper target will be chosen by the consumer.

If you want platform-dependent dependencies, then you need to use that platform’s target. If you don’t, then you don’t want a target but just another sourceSet @GarouDan

Thanks guys 😃. So if I would like to use this code on all possible platforms I need to create a preset for each of them and configure its source sets to depend the common one and nothing more. Is that right?

Projects and folders are not the same thing, and a sourceSet is basically a folder with dependencies

Yes, I understand your point. I already know that, indeed I have a lot of source sets. My doubt is that I would like to use this code from another folder / project outside.

Well if you have something in one project that you need to use in another project, then that thing needs to be a project

Just to make sure we are understanding each other. If we have two projects (in the same repository). One living in the folder

common

and the other one living in the folder

android

(where we could have some other ones on different folders, but I simplifying here for brevity). Do you think that is possible to use the

common

project inside the

android

project (maybe using something like

implementation project(':common')

) without defining any presets in the

common

project?

For

common

to be able to be consumed by

android

, you need a

jvm

or

android

target in

common

.

Ok, I understand how it works now = ) Thanks a lot all of you
