I tend to think that tasks themselves shouldn't have defaults, but the plugins which create them should set them. However, there are some cases where you want defaults, for example when the user can create additional tasks. In this case I think the easiest is to do it in the task constructor, eg, here, calling

inputDirectory.from(...)

in the ctor

One thing that concerns me here is if some properties (e.g. workingDir in Exec) doesn't work with delegated properties, as it likely hasn't been set yet in the constructor

Maybe you shouldn't extend the

Copy

and

Exec

tasks, and rather use the

FileSystemOperations#copy

and

ExecOperations#exec

from your task action.
