While updating the latest build tools and Gradle version we noticed that there are some deprecation issues that should be addressed and some improvements.

• Migrate to maven publish plugin
• Use new Gradle plugin DSL:

plugin {
    id 'java' version '1.0'
}

• There is a bunch of optional variables hidden in the Gradle files, that aren't defined in the dependecies.list file. In order to facilitate its discovery and setup, we should define them in the dependencies.list file.
• ndkVersion variable is not used, and it's defined twice
• Jenkins file can be upgraded. Use pipeline step
