Force rerun a task by another task

As I said, I’m not fluent in kotlin. TBH I find the source quite ugly but that’s just me.

I’m assuming you’ll need two compile tasks in the service project. One for src/main/kotlin and another for the allgenerated sources.

I’m also assuming that the kotlin plugin works in the same way as the java plugin. Which means if you add another SourceSet that it will automatically add a KotlinCompile task to the model.

So perhaps you could do:

project(':service') {
   configurations {
      allgenerated
   } 
   sourceSets {
      allgenerated { // this adds a SourceSet which adds the compileAllgeneratedKotlin task to the model 
         kotlin.srcDir "$buildDir/allgenerated" 
      } 
   } 
   dependencies { 
     // as above 
   } 
   // compile tasks usually work with directories so 
   // might need to copy the configuration to a known directory 
   task copyAllGenerated(type:Copy) {
      from configurations.allgenerated
      into "$buildDir/allgenerated" 
   } 
   // wire the copy task into the DAG
   // task name might be different 
   compileAllgeneratedKotlin.dependsOn 'copyAllGenerated' 
} 

Or perhaps you want the extra compile step in each of the subprojects? And the service project collects the class files and builds a jar?

Eg

project(':a') {
   configurations { generated }
   sourceSets {
      generated {
         kotlin.srcDir "$buildDir/generated"
      }
   } 
   dependencies {
      generated tasks.compileGeneratedKotlin
   } 
   task generate {
      outputs.dir "$buildDir/generated" 
      ... 
   } 
   compileGeneratedKotlin.dependsOn 'generate' 
   ...
} 

I think the second approach is cleaner since the extra copy task isn’t required (the directory is “known” to the compile tasks since generate and compile are in the same project)
