Convert muzzle plugin to kotlin by bric3 · Pull Request #9439 · DataDog/dd-trace-java

bric3 · 2025-08-29T14:38:50Z

What Does This Do

Port the MuzzlePlugin written in groovy to Kotlin. Also spread the single source file to its constituents.

Motivation

Significantly better IDE support, this will improve maintainability.
In a previous PR this plugin was refactored to use lazy configuration API, this PR don't change that. However, it improves in a few places.

Additional Notes

Review strategy suggestion: go commit by commit, as I migrated piece of code one by one.

Related to

Configure lazily MuzzlePlugin #9315

Conversion method:

Spread classes that were in the same groovy file
Method by method conversion.

I reviewed this PR by comparing the new kotlin files to the previous groovy implementations. Looks like all of the classes and logic were transferred directly over. Nice! Thanks!

mcculls · 2025-09-11T17:09:04Z

Couple of issues I don't see with the original plugin:

./gradlew :dd-java-agent:instrumentation:mule-4:muzzle
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':dd-java-agent:instrumentation:mule-4'.

./gradlew :dd-java-agent:instrumentation:spring-webflux-5:muzzle

(This also fails for :dd-java-agent:instrumentation:spring-webflux-6:muzzle)

I also noticed that the ./gradlew printReferences task doesn't generate any output, only errors:

Those projects are all intermediate modules which don't have any source sets/code - I suspect there's a check missing in the new plugin that should be skipping these projects.

…he JavaPlugin applied This can happen on empty parent projects.

bric3 · 2025-09-12T11:40:48Z

@mcculls thank for catching those !

I'm not sure what made the build green in the first place.

1st issue was due to Groovy adding a GStringImpl to a `List.
2nd issue was an oversight from me used name instead of nameSlug
3rd issue was also n oversight I only tested printReferences on specific projects, but empty non-java parent projects also had the muzzle plugin applied and this failed.

LGTM - thanks!
