       // PROBLEM
       // ----------
    
       // The url for the Oracle.com maven repo is supposed to be: 
       //
       //    https://maven.oracle.com
       //
       // But gradle can't handle the redirects needed by the realm-based SSO


       // WORKAROUND
       // ----------

       // A workaround [1] is to use this URL:
    
       url "https://www.oracle.com/content/secure/maven/content"

       // [1]: https://groups.google.com/forum/#!topic/gradle-dev/G8X_41lOIlU


       // METHOD 1 - plain-text credentials in build file
       // ---------------------------------------------------------

       // You don't need to set the 'name' property if using this method.


       // Uncomment this credentials block and enter Oracle Account credentials

       //credentials {
       //  username '<email address>'
       //  password '<password>'
       //}


       // METHOD 2 - credentials in .m2/settings.xml, optionally encrypted
       // ----------------------------------------------------------------

       // This method uses maven's settings.xml and settings-security.xml, as
       // described here:
       // https://blogs.oracle.com/dev2dev/entry/how_to_get_oracle_jdbc
       // 
       // NOTES:
       //
       // 1) you must set the 'name' property. And its value must match the
       //    'id' you used in the 'server' config in your ~/.m2/settings.xml
       //
       // 2) include the 'net.lingquica.maven-settings' plugin, as shown at the
       //    top of this file. This plugin allows your gradle project to use
       //    maven's settings.xml to store repository authentication 
       //    credentials, optionally encrypted.

       name "maven.oracle.com" // must match server id in settings.xml !
