    // Adding dependencies on JAXB explicitly.

    // JAXB 2.2.11 is chosen here because:
    // 1. JDK 8's bundled JAXB is 2.2.8. Better with a closer version while we are on Java 8.
    //    https://javaee.github.io/jaxb-v2/doc/user-guide/ch02.html#a-2-2-8
    // 2. Neither com.sun.xml.bind:jaxb-core:2.2.8 nor com.sun.xml.bind:jaxb-impl:2.2.8 does not exist on Maven Central.
    // 3. 2.2.11 looks to be used by the most Java libraries among JAXB 2.2.
    //    https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api
    //    https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-core
    //    https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-impl
    // 4. JAXB 2.2.8 and 2.2.11 look to have the same set of classes.
    //    Although their internal implementations are a bit different, class loaders would not be confused.
    compile "javax.xml.bind:jaxb-api:2.2.11"
