Gradle - get resolved version of a dependency

resolvedVersionOf

def getResolvedVersionOf(dependency) {
    return configurations.compile.resolvedConfiguration.firstLevelModuleDependencies.asList().collectAll { e ->
        if (e.moduleName == dependency) {
            return e
        }
    }[0].moduleVersion
}

I trimmed it down a bit by using findAll():

def getResolvedVersionOf(dependency) {
    return configurations.compile.resolvedConfiguration.firstLevelModuleDependencies.findAll { it.moduleName == dependency }[0].moduleVersion
}
