IIRC the knative CRDs are already exposing a good API.
This makes it a good candidate to switch to totally generated extensions in the knative repository.

Any reference to a specific repository/CRDs we should look at?
Anyone from knative that can help and evaluate this effort?

[rohanKanojia]

we can try doing it. But let's do it in a two-step process:

1. Write tests for all exposed CRD types with go generator
2. Migrate to Java generator (all tests written in previous step should still pass)

[andreaTP]

Switching to the java-generator is going to be a breaking change, even if we test all of the types we need to convert them again.

[rohanKanojia]

we need to convert them again.

Sorry, I don't understand this.

[andreaTP]

The java-generator is not going to generate the same types as the current extension.

If it's possible, we should follow the same approach we did for Camel-K.

• The official repository to host an extension generated by our Java Generator (analogous to [proposal] Publish a generated extension for Java apache/camel-k#3994)
• Deprecation of our extension (analogous to [java-generator] Remove preview and deprecate Camel-k extension #5107)
• Removal of our extension (analogous to Remove Camel-K extension #5171)

[rohanKanojia]

This seems to be blocking my work on #5113 .

For now we can proceed with just updating go dependencies.

I've created #5348 for migration to Java generator task.
