/**
    Maven Resolution Strategy
    =========================

    Description:

    Adds ability to set Maven-like conflict resolution strategy for any configuration

    | Maven works on the principle of nearest wins strategy while resolving the dependency
    | conflicts, that means whichever version it finds nearer in the tree, it will take
    | that version and ignore the other versions.
    | [http://techidiocy.com/maven-dependency-version-conflict-problem-and-resolution/]

    Usage:

    1. Type `maven()` inside `resolutionStrategy` closure param

    Example (apply to all configuration):

        configurations.all.resolutionStrategy { maven() }

    Example (apply to compile configuration):

        configuration.compile.resolutionStrategy { maven() }
 */
project.configurations.all {
    resolutionStrategy.extensions.add "maven", {
        def versionMap = new HashMap()
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def moduleId = "${details.requested.group}:${details.requested.name}" as String
            if (!versionMap.containsKey(moduleId)) {
                versionMap[moduleId] = details.requested.version
            } else {
                details.useVersion versionMap[moduleId]
            }
        }
    }
}
