is there a trick to use the kotlin DSL when I am writing a gradle plugin? my build.gradle looks like

plugins {
    id 'java-gradle-plugin'
    id 'org.jetbrains.kotlin.jvm'
}

dependencies {
    compileOnly gradleApi()
    implementation "org.scalastyle:scalastyle_2.12:1.0.0"

    testCompileOnly gradleApi()
    testCompile 'junit:junit:4.13.1'
    testImplementation "org.junit.jupiter:junit-jupiter-api:$junit5Version"
    testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:$junit5Version"
    testImplementation("org.junit.jupiter:junit-jupiter-params:$junit5Version")
    testImplementation "org.assertj:assertj-core:$assertJVersion"
}

and i cant seem to access the project.tasks.register<TaskType>(name: String) among other things

There’s a good guide in the Gradle documentation for migrating scripts from Kotlin to Gradle. Creating and configuring tasks, in particular, is quite different from Groovy https://docs.gradle.org/current/userguide/migrating_from_groovy_to_kotlin_dsl.html#configuring-tasks

AFAIK no - as Kotlin DSL is generated by Gradle on first run. You need to introduce similar functions in your plugin codebase

Both answers are wrong or misleading, so here again for reference what I wrote in the duplicate question in the Gradle Slack:

Not so much a trick, just a missing dependency: compileOnly gradleKotlinDsl()
But actually you usually want to apply the kotlin-dsl or kotlin-dsl.base plugins to for example also get the SAM conversion for Gradle interfaces.
kotlin-dsl applies java-gradle-plugin, kotlin-dsl.base, and kotlin-dsl.precompiled-script-plugins plugins
kotlin-dsl.base plugin applies embedded-kotlin, adds gradleKotlinDsl() to the dependencies of compileOnly and testImplementation configurations, and configures the Kotlin DSL compiler plugins for example for proper SAM conversion for Action and similar.

What is generated and only for build scripts and precompiled script plugins, are the accessors for extensions that were added by plugins applied using the plugins block. But all the standard things like register with type parameter and similar is available in that dependency.
