Has anyone successfully accessed the test-retry (or develocity) plugin's Test task extension programmatically via a Java or Groovy binary plugin?

I'm doing something like:

```project.tasks.register('myCustomTestTask', Test {

  TestRetryTaskExtension retry = it.extensions.getByType(TestRetryTaskExtension)
  ...
}```
... but this throws o.g.a.UnknownDomainObjectException: Extension of type 'TestRetryTaskExtension' does not exist.

kotlin binary plugin but should get you there.
```        target.tasks.named&lt;Test&gt;("test") {
            useJUnitPlatform()
            testLogging.showStandardStreams = true
            extensions.getByName&lt;DevelocityTestConfiguration&gt;("develocity").apply {
                testRetry {
                    maxRetries.set(1)
                    maxFailures.set(2)
                    failOnPassedAfterRetry.set(false)
                }
            }
        }```
type is `com.gradle.develocity.agent.gradle.test.DevelocityTestConfiguration`

might also be that its a custom test task? might need to make sure the develocity extension is on it.

Yeah seems like a chicken/egg problem related to being a custom task.

Bring back `afterEvaluate`! (kidding)

Maybe I need to wrap this in a closure which reacts to the develocity plugin...

Hmmm `develocity` plugin in a Settings plugin; not sure how to react to whatever it's doing to manipulate Test tasks :thinking_face:

yeah that was the thought I had. probably worth a zendesk ticket to ask them how to get it onto the custom test task

Everything working as it should - problem was me
