# dokka

[atsushieno]

Hi, I am currently stuck at this https://stackoverflow.com/questions/71998578/execution-failed-for-task-appdokkahtml in my project (like this https://github.com/atsushieno/ktmidi/actions/runs/3220797604/jobs/5267956067#step:9:11495). None of the workarounds written there (removing those auto-generated targets) worked for me. Is it a known issue?

Hi! I think it's a configuration problem.

You've applied Dokka only to ktmidi module, but it's not present in the parent build.gradle script. I would start with that and see if it works

If Dokka worked before and all of a sudden stopped working, did you upgrade AGP version recently? If so, it might be related to #2472.

AGP started shipping unshaded Dokka 1.4 some versions ago, and it's conflicting with newer version of Dokka (such as 1.7).

If you run ./gradlew buildEnvironment in the root project directory you'll actually see that you have Dokka 1.4.32 on the classpath

and if you run ./gradlew ktmidi:buildEnvironment, you'll see that it has Dokka 1.7.10 on the classpath

These two are not compatible, so running ./gradlew clean :ktmidi:dokkaHtml --stacktrace results in this:

Caused by: java.lang.NoSuchMethodError: 'java.util.Set org.jetbrains.dokka.DokkaDefaults.getDocumentedVisibilities()'

which is somewhat expected

This issue should be resolved in AGP 7.3, I see you're currently using 7.2

[Ignat Beresnev]

TLDR: either upgrade AGP to 7.3 or try adding Dokka to the root build script (can do with apply = false ), it'll override Dokka 1.4 shipped with AGP with the newer version then.

Awesome, those are so informative, thanks. Let me first try your patch. My project structure has changed a lot (they used to be separate "projects") so former versions are not comparable.

[atsushieno]

Yes, that fix/workaround for #2472 worked. Thanks a lot!
