* What went wrong:                                                                                                                                                                 
A problem was found with the configuration of task ':myTask' (type 'MyTask').                                                                                                      
 - Type 'MyTask' property 'input' has @Input annotation used on property of type 'File'.                                                                                          
                                                                                                                                                                                  
   Reason: A property of type 'File' annotated with @Input cannot determine how to interpret the file.                                                                            
                                                                                                                                                                                  
   Possible solutions:                                                                                                                                                            
     1. Annotate with @InputFile for regular files.                                                                                                                               
     2. Annotate with @InputFiles for collections of files.                                                                                                                       
     3. If you want to track the path, return File.absolutePath as a String and keep @Input.

When multiple errors occur this is a weird way of representing it.

We'll deliver an adapted version of this with validation reports in the near future.

The PR will stay there till we can integrate validation reports
