   could you try construction, may be it can help

   clean {
       delete 'preprocessed-path'
   }

   also I saw some examples where guys recommend to use construction for tasks

   outputs.upToDateWhen { false }

   I think outputs.upToDateWhen { false } works!
   The java-comment-preprocessor folder gets regenerated after every clean.
   I'm not sure everything works yet since I've got some problems with Kotlin sources thinking they are redeclarations, but I still have some things to try out :).
   Thanks!

   Okay nice! It works :) thanks!

   For future reference, I'll put some examples for projects with Kotlin and Scala code (using gradle kts):

   val kotlinMainSources = kotlin.sourceSets.main.get().kotlin.sourceDirectories
   
   val preprocessMain by tasks.creating(JcpTask::class) {
       sources.set(kotlinMainSources)
       clearTarget.set(true)
       fileExtensions.set(listOf("kt"))
       vars.set(Versions.versionMap)
       outputs.upToDateWhen { target.get().exists() }
   }
   
   tasks.compileKotlin {
       dependsOn(preprocessMain)
       outputs.upToDateWhen {
           preprocessMain.outcomingFiles.files.isEmpty()
       }
   
       doFirst {
           kotlin {
               sourceSets {
                   main {
                       kotlin.setSrcDirs(listOf(preprocessMain.target.get()))
                   }
               }
           }
       }
   
       doLast {
           kotlin {
               sourceSets {
                   main {
                       kotlin.setSrcDirs(kotlinMainSources)
                   }
               }
           }
       }
   }

   val scalaMainSources = sourceSets.main.get().scala.sourceDirectories
   
   val preprocessMain by tasks.creating(JcpTask::class)  {
       sources.set(scalaMainSources)
       clearTarget.set(true)
       fileExtensions.set(listOf("scala"))
       vars.set(Versions.versionMap)
       outputs.upToDateWhen { target.get().exists() }
   }
   
   tasks.compileScala {
       dependsOn(preprocessMain)
       outputs.upToDateWhen { 
           preprocessMain.outcomingFiles.files.isEmpty()
       }
   
       doFirst {
           scala {
               sourceSets {
                   main {
                       scala.setSrcDirs(listOf(preprocessMain.target.get()))
                   }
               }
           }
       }
   
       doLast {
           scala {
               sourceSets {
                   main {
                       scala.setSrcDirs(scalaMainSources)
                   }
               }
           }
       }
   }

   Edit: Updated so IntelliJ plays nice by only temporarily changing the source folders.
   Edit2: Updated again to make intellij not do incremental code changes without jcp
