Pick Version with Branchname as Classifier with Gradle

Question

I am evaluating gradle for our project. We have multiple small project that contain small util libraries. Most projects are in an extra repository and cannot use a shared buildscript. When working across multiple project the same feature branch is used. I already managed to get gradle to put the branchname into the created maven artifact as classifier. For our continous integration it would be really helpful to resolve a dependency to such a library to the one using its own branch name if it exists. If it doesn't it should fallback to the normal declared version.

I managed to change the versions via resolutionStrategy.eachDependency but I couldn't find a way to implement the fallback if no version for this branch exists.

Is there any way this can be achived?

You'll have to write some code to achieve this. For example, you could copy the configuration, set classifiers for the copied configuration via resolutionStrategy.eachDependency, resolve the copied configuration via configuration.resolvedConfiguration.lenientConfiguration, check which dependencies could be resolved, and then choose classifiers for the original configuration accordingly (again via resolutionStrategy.eachDependency). The best place to do all of this is in configuration.incoming.beforeResolve.
