Exclude all compiled classes from jar built by gradle java project

I have a gradle java project with custom task which generates some files during build. I need to produce jar artifact containing ONLY generated files. Problem: jar contains both generated files and class files.



Exclusion of *.java files from source sets is impossible because I need compiled classes for generation.



jar {

  exclude("**/*.class")

  from ("$buildDir/generated-files-dir")

}


Snippet above removes class files but leaves directories as is.






java gradle jar

          Add includeEmptyDirs = false to your jar task.



          jar {
          
  exclude("**/*.class")
          
  includeEmptyDirs = false
          
  from ("$buildDir/generated-files-dir")
