I’m using 3.0.1 in AS 3.0.1

Maybe you could try to reproduce this on sample project.
If it’s a bug of Android Plugin would be nice to report an issue and attach this sample project

[jermainedilao]

@gildor got it, already tried on a sample project. it builds successfully if only one local module is added (either java library or android library). App goes into limbo once i add another new local module.

[gildor]

Probably I know what is the reason of this behavior

[gildor]

Probably problem with different class paths

[gildor]

replace implementation with api in your domain

[gildor]

implementation dependency hidden from consumer of module with this dependency, it’s special feature of Gradle that allows to use some dependency only internally for some module, without leak abstractions. But if some module expose some type of dependency, you should use api instead.

[gildor]

I’m not 100% sure, but you can try to check this

[jermainedilao]

@gildor you mean, instead of using implementation project(':domain') in my data build.gradle i will use this api project(':domain')?

[gildor]

yes, in your subprojects. In your app module you still use implementation

[jermainedilao]

I see. let me try

[gildor]

this is simple rule:
- if module uses dependency only internally and you don’t expose types of dependency. use implementation, it allows you in the future remove or replace this dependency and don’t worry that some consumer used it.
- If module uses dependency and expose some types/classes of this dependency to own consumers, use api. In this case dependency public API now part of your module public API

Oh my, you’re going to hate me for this. As I was doing what you said above ^. I noticed that in my domain build.gradle. apply plugin: 'kotlin' line is missing. Build, and voila. Build succeeded. Thanks so much for the input! I learned something new today.

[gildor]

😱

[gildor]

Ohhh %) Nice. Still not clear for me why you get such error message.

[jermainedilao]

Ikr. Error bit misleading. build failed during compileDebugKotlin was my only clue

[James Coggan]

done that in the past, AS doesnt add kotlin to new modules automatically 😕
