I have a question about configuring my Hierarchical Project Strucutre. First to give some contex. Say I have a project that contains two source sets:

jvm

and

js

.

common

is automatically created as well. Code in the

common

module cannot contain java classes or js classes. The only things that are allowed in

common

are those thar are compatible with

jvm

and

js

. Now say I have another project. This one only has a single source set:

jvm

.

common

is still autoamtically created. However, in this case,

common

is allowed to contain java classes. My understanding is that kotlin Multiplatform automatically configures

common

to allow anything that would be able to compile for each target in the project. Here is my question. I do not want

common

to behave differently depending on the targets that exist in a particular subproject. Rather, I would like for

common

to mean the same exact thing in each subproject regardless of the targets present. If I take a project that only has a single

jvm

source set, and want to add a

js

source, I want to know that the

common

source set will automatically be compatible. However, I do not want to add a

js

and a

jvm

source set to every single subproject, even if they would be blank. Basically, I want to disable the feature that configures

common

to have different dependencies based on which source sets are present. If I want to have a common source set that contains java classes for say, jvm desktop + android, then I will create this source set manually or with the incubating hierarchy template feature.

Kotlin compiler doesn't know what is common to all platforms, it only knows about the platform it is currently building for (common code gets rebuilt for each target platform) so it's not really a feature to "disable"

It also doesn't know about future targets. Maybe WASM prevents using something that every other target allows. Now when you update your Kotlin version to one with WASM support what behavior should happen? All your code stops compiling?

Thanks for sharing the YouTrack issue. That’s pretty much what I am looking for.
