And 7 more times like this for every other gradle task.

🔬 How To Reproduce

Create a new empty Android project using Android Studio Hedgehog.
Add hivemq-mqtt-client and mqtt-client-websocket v1.3.3 as dependencies.
Rebuild the project and see the build errors.

Note: this can't be reproduced with AGP 8.1.4!

I got the same error after upgrading agp from 8.1.4 to 8.2.x.

digrec commented 4 months ago

Any update on this issue? This makes AGP 8.2+ unusable on MQTT projects, and AGP 8.3 is already out for new AS Iguana!

If anyone has a workaround for this, please share it here!

bddckr commented 4 months ago

I don't have this issue. I'm using com.hivemq:hivemq-mqtt-client-websocket:1.3.3 in an Android library project. AGP 8.3.0, Gradle 8.6.

digrec commented 4 months ago

In my empty app project, as in my first post, using AGP 8.3 with Gradle 8.4 or 8.6 does not help. Errors are the same:

Gradle 8.6 just additionally points out to the docs for variant selection errors and some possible reasons: https://docs.gradle.org/8.6/userguide/variant_model.html#sub:variant-no-match

Try:
> Review the variant matching algorithm at https://docs.gradle.org/8.6/userguide/variant_attributes.html#sec:abm_algorithm.

Please replace implementation 'com.hivemq:hivemq-mqtt-client-websocket:1.3.3' with implementation(platform('com.hivemq:hivemq-mqtt-client-websocket:1.3.3'))

@SgtSilvio that's it, thank you! My bad for not checking the repo README.
