A problem was found with the configuration: 'overrideService$kt2ts_plugin' is missing

[TobseF]

Running a Gradle build fails with a configuration problem: overrideService$kt2ts_plugin' is missing an input or output annotation:

A problem was found with the configuration of task ':kt2ts' (type 'Kt2TsTask').
  - In plugin 'se.jensim.kt2ts' type 'se.jensim.gradle.plugin.kt2ts.Kt2TsTask' 
     property 'overrideService$kt2ts_plugin' is missing an input or output annotation.

I have used the example config. I only changed the annotation to match my type.

kt2ts {

    // Repeatable block for linking outputfile to a set of annotations
    output {
        outputFile = file("$buildDir/ts/pss-api.d.ts")
        annotations = listOf("de.tfr.util.GenerateTS")
    }
    
    classFilesSources {
        // Two ways of setting classes dir, if both are set, both are jointly used
        // One has to be provided (for task input resolution to work properly, I made it mandatory)
        compileTasks = listOf(tasks.compileKotlin)
        classesDirs = files("$buildDir/classes/kotlin/main")
    }
    
}

It fails without generating any .ts file.
