I’m currently developing a small shared plugin for few projects and the cleanest solution would be if I could read and process a resource file provided by the plugin. However, Java/Kotlin style this.javaClass.getResouce(...) always returns null

|- src/main/kotlin/myplugin.gradle.kts
|- src/main/resources/file.txt
|- build.gradle.kts
|- settings.gradle.kts

myplugin.gradle.kts

tasks {
    val mytask by registering(DefaultTask::class)
    mytask {
        doLast {
            println(this.javaClass.getResource("file.txt")) // Always returns `null`
        }
    }
}

Is there a clean simple way to access/read a resource file provided by the plugin it self?

PS: The this.javaClass is org.gradle.api.DefaultTask_Decorated which does explain why the file is not found. However, it does not help me with reading the actual resource file.
