build.gradle

allprojects { project -> 

    configurations.all {
        resolutionStrategy {
            //... Fail eagerly on version conflict (includes transitive dependencies)
            //... For e.g. multiple different versions of the same dependency (group and name are equal)
            failOnVersionConflict()

             //... Force certain versions of dependencies (including transitive)
            force libraries.scala_library
            force libraries.slf4j_api
            force libraries.commons_logging
            force libraries.commons_lang
