## Interface SourceSet

-     public interface SourceSet

  A `SourceSet` represents a logical group of Java source and resources.

  See the example below how `SourceSet` 'main' is accessed and how the `SourceDirectorySet` 'java' is configured to exclude some package from compilation.

       apply plugin: 'java'

       sourceSets {
         main {
           java {
             exclude 'some/unwanted/package/**'
           }
         }
       }
