java - How to get the Files that have changed since the last run of a Gradle Task? -

i have following gradle task:

class mytranslatetask extends defaulttask {      @inputfiles filecollection srcfiles     @outputdirectory file destdir      @taskaction     def run() {     ...     } }  

how can files srcfiles have changed since last run of task?

gradle 1.6 introduced incubating feature called incrementaltasksinputs allows access files changed or removed since last task run.

ref: https://gradle.org/docs/current/dsl/org.gradle.api.tasks.incremental.incrementaltaskinputs.html

class incrementalreversetask extends defaulttask {      @inputdirectory      def file inputdir       @outputdirectory      def file outputdir       @taskaction      void execute(incrementaltaskinputs inputs) {          inputs.outofdate { change ->              def targetfile = project.file("$outputdir/${change.file.name}")              targetfile.text = change.file.text.reverse()          }           inputs.removed { change ->              def targetfile = project.file("$outputdir/${change.file.name}")              if (targetfile.exists()) {                  targetfile.delete()              }          }      }  }
