Declares the tasks to build a custom 
BinarySpec binary.
 The following example demonstrates how to register multiple tasks for custom binary using a plugin with a
 
BinaryTasks annotation.
 
 @Managed interface SampleComponent extends ComponentSpec {}
 @Managed interface SampleBinary extends BinarySpec {}
 apply plugin: MyCustomBinariesPlugin
 class MyCustomBinaryCreationTask extends DefaultTask {
      @TaskAction void build() {
          //building the binary
      }
 }
 class MyCustomBinariesPlugin extends RuleSource {
     @ComponentType
     void register(TypeBuilder<SampleBinary> builder) {}
     @BinaryTasks
     void createBinaryTasks(ModelMap<Task> tasks, SampleBinary binary) {
         tasks.create("${binary.name}Task1", MyCustomBinaryCreationTask)
         tasks.create("${binary.name}Task2") {
             dependsOn "${binary.name}Task1"
         }
     }
 }
