I can see differences between the guide and your code

1. you have afterEvaluate {}. Why is this?
2. you're creating a new publication

publications {
                register<MavenPublication>("release") {

while the guide isn't - it is configuring all publications

publications.withType<MavenPublication> {

Kotlin Multiplatform automatically registers a MavenPublication, so you shouldn't need to do it yourself.

[Abhishek Agarwal]

@Adam S I get this error when I copy paste the exact same code

Reason: Task ':noober:publishAndroidDebugPublicationToSonatypeRepository' uses this output of task ':noober:signAndroidReleasePublication' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.

[Adam S]

ah okay, yes that's a bug https://youtrack.jetbrains.com/issue/KT-46466

Here's a better workaround - remove afterEvaluate {} and add this at the bottom of the file

tasks.withType<AbstractPublishToMaven>().configureEach {
  val signingTasks = tasks.withType<Sign>()
  mustRunAfter(signingTasks)
}

[Adam S]

you can also take a look at this publishing convention plugin. It's a little more idiomatic Gradle, but the end result should be the same. Use whichever version works for you.

Thanks for helping, will try both solution.

[Abhishek Agarwal]

Hey @Adam S, the first solution worked well, thanks again for helping me out.
