Hi Andrew,
I have two assumptions about your problem:
1. the assignment of the input files should be done during the
configuration phase of the task and not in a doLast closure. In your
existing task setup, the input files are never considered.
2. when gradle is executed, it stores the hash of the output file. If you
never create one, even though you marked a specific path for the output
file, gradle recognizes, that the output file of your task hasn't changed
(since it does not exist after your first run, the second run of your task
(create a non existing outputfile) is up-to-date.
regards,
René
