isIncremental

Indicates if it was possible for Gradle to determine which exactly input files were out of date compared to a previous execution. This is not possible in the case of no previous execution, changed input properties, output files, etc.

When true:

• Any input file that has been added or modified since previous execution will be considered 'out-of-date' and reported to #outOfDate.
• Any input files that has been removed since previous execution will be reported to #removed.

When false:

• Every input file will be considered to be 'out-of-date' and will be reported to #outOfDate.
• No input files will be reported to #removed.
