Integrate Gradle building into Eclipse

To fully replace ant within Eclipse IDE, Eclipse requires a plugin called "buildship" which integrates gradle.
Also, the gradle build also needs to utilise an eclipse plugin to effectively complete the integration.

In build.gradle, add
plugins {
 id 'eclipse'
}

eclipse {
 // some optional configuration
}

and for each defined task add a group and description
task myTask {
  group="build"
  description="complete build of application"
}

and finally run

gradle eclipse

to generate the .project and .classpath files.
