Mediating between nebula-release and cognifide aem: which one is right?

[sabberworm (Raphael Schweikert)]

So when I use both

plugins {
    id("com.cognifide.aem.tooling") version "9.0.6"
    id("nebula.release") version "13.1.1"
}

the build configuration phase fails with:

FAILURE: Build failed with an exception.

* Where:
Build file 'build.gradle.kts' line: 8

* What went wrong:
An exception occurred applying plugin request [id: 'nebula.release', version: '13.1.1']
> Failed to apply plugin [class 'nebula.plugin.release.git.base.BaseReleasePlugin']
   > Could not create task ':sync'.
      > Could not create task of type 'Sync'.
         > Instance named '*' is not defined.

BUILD FAILED in 1s

(where the Sync task is a task from the AEM plugin)

Both plugins configure fine individually. The order does not matter (if I order com.cognifide.aem.tooling last, the message changes to An exception occurred applying plugin request [id: 'com.cognifide.aem.tooling', version: '9.0.6'] but otherwise stays the same).

I guess I kinda know what the problem is:

1. The constructor of the Sync task (an of many other tasks created by the AEM plugin) calls a method on the AemExtension that throws unless the extension has been correctly configured.
2. Nebula accesses the tasks in its setup logic and does not use the methods from Task Configuration Avoidance, forcing the tasks to be instantiated. The default config (let alone the custom config from my build.gradle.kts) for AemExtension (which is sufficient for the method not to throw) hasn’t been initialized at this point.

Can anyone tell me which of the plugins is doing it wrong so I can open the defect at the correct place?

Argument for nebula being the culprit:

• Forcing creation of tasks from other plugins in your plugin seems like a code smell.

Argument for AEM tooling being the culprit:

• AFAICT not using task configuration avoidance best practices is discouraged for performance reasons but not disallowed.
• Maybe it configures the default values for its extensions too late?

Which one is it?
