Android AmbiguousConfigurationSelectionException with Gradle 4.9 and local dependencies

[martofeld]

After migrating to Gradle 4.9 I started getting the issue I mentioned above.

Environment: Gradle Version: 4.9 and 4.8 Nebula Version: 6.0.0 Android Gradle Plugin: 3.1.0

The issue occurs when I have modules with dependencies to other local modules.

My build.gradle is:

dependencies {
    api project(':local_module')
}

I have also tried using implementation and still got the same issue.

Let me know if you need any more information

The full stacktrace is:

[sghill]

@martofeld Have you tried the dependency lock built into Gradle?

[martofeld]

@sghill It is not our intention to migrate from this plugin since we have a great deal of scripts depending on how nebula works. However, as a side note, Gradle mentions you and mentions a migration guide which I am yet to find. Do you think you could point me in the right direction?

[rpalcolea]

We don't have a formal migration guide.

@OdysseusLives do you have any insight for this? perhaps share some notes around the migration task that is not included?

[OdysseusLives]

I'll update the project with a migration guide, based off of the release notes for these two versions:

https://github.com/nebula-plugins/gradle-dependency-lock-plugin/releases/tag/v7.3.1 details setting a system property, using the task migrateToCoreLocks to migrate existing locks, and the option to lock all configurations (as we do not intend to lock every configuration by default, as some are added via plugins).

https://github.com/nebula-plugins/gradle-dependency-lock-plugin/releases/tag/v7.6.3 details locking additional configurations to lock, via a property dependencyLock.additionalConfigurationsToLock. This would be used if you have a one-off configuration that you define in your project that you would like locked and don't see a lockfile when running dependencies --write-locks
