 *  Fix: Configure the multiplatform artifact (`com.squareup.okhttp3:okhttp:3.x.x`) to depend on the
    JVM artifact (`com.squareup.okhttp3:okhttp-jvm:3.x.x`) for Maven builds. This should work-around
    an issue where Maven doesn't interpret Gradle metadata.

    `DurationUnit` which was a typealias in 1.5.x.
