There are several task annotations.  
[https://docs.gradle.org/current/userguide/more\_about\_tasks.html#sec:task\_input\_output\_annotations](https://docs.gradle.org/current/userguide/more_about_tasks.html#sec:task_input_output_annotations)  
See table 1

- @Input
- @InputFile
- @InputDirectory  
etc.  
Should these be used in conjunction with plugin extensions?
