Hello. I am having problems when referencing third party libraries in the common source folder. I have added kotlinx.serialization and am using it successfully in the app. However in the AndroidStudio source editor all classes from the serialization library are marked as unresolved and no tooling works for them. Is anybody aware of such an issue?

[Adam Cooper]

you might need to install/apply the kotlinx.serialization gradle plugin

[Adam Cooper]

plugins {
    kotlin("plugin.serialization") version "1.7.20"
}

[Moritz Post]

The issue applies to all third party dependencies declared in the commons dependency section not only serialization. I am also using the libraries. So everything compiles fine but the tooling is missing.

[Adam Cooper]

I see. If it builds correctly, I'm pretty sure that means the model is correct. So you might need to manually sync your gradle project, or invalidate the IDE's caches and restart (you can find both of those in the actions search menu)

[Moritz Post]

Did all of the above. To no success.

What version of AS are you using?

[Moritz Post]

that is on AS canary

[Moritz Post]

Just opened the project on AS beta. Same issue.

[Moritz Post]

and also on AS stable

I usually have to apply this hack to get AS to work

@eygraber I am not sure where to apply this function. Could you give me a hint?

[eygraber]

You can put the body of that function in your kotlin block

[Moritz Post]

@eygraber Unfortunately this did not help.

[Moritz Post]

opening the project in stable IntelliJ and setting the android gradle plugin version to its max supported value of 7.2.0 does resolve the common dependencies correctly

[Moritz Post]

Opening the project in AS canary (with kmm plugin installed) but keeping the android gradle plugin at 7.2.0 does again not resolve the dependencies correctly.

Try invalidate cache and restart
