Gradle RuntimeException '@FormParam' and '@RestForm' can only be used on methods annotated with '@Consumes(MediaType.MULTIPART_FORM_DATA)'

[arey]

Describe the bug

I've been working for a few months on a Spring Petclinic fork based on Quakus. It uses almost all the Spring extensions provided by Quarkus : Spring DI, Spring Web, Spring Data JPA, Spring Cache and Spring Boot

I've noticed a difference in behaviour between the Gradle and Maven builds of my quarkus-spring-petclinic application.

The Maven build succeeds. The Gradle build fails. I don't know why?
Both build configurations should be using the same Quarlus artifact versions.

Expected behavior

With the same Java base code, gradle and maven build should produces the same behaviour.

Actual behavior

Successful Maven build logs can be found here: https://github.com/spring-petclinic/quarkus-spring-petclinic/actions/runs/14236867795/job/39897740064
Below I explain how to reproduce the Gradle error. I have attached my local logs to this post:
gradle.log.zip

The stacktrace:

Caused by: java.lang.RuntimeException: '@FormParam' and '@RestForm' can only be used on methods annotated with '@Consumes(MediaType.MULTIPART_FORM_DATA)' '@Consumes(MediaType.APPLICATION_FORM_URLENCODED)'. Offending method is 'org.springframework.samples.petclinic.owner.OwnerRepositoryJaxRs_67b39fdc404ae23c4212d0aee4054338ea689aef#jakarta.ws.rs.core.Response add(org.springframework.samples.petclinic.owner.Owner entity, jakarta.ws.rs.core.UriInfo uriInfo)'
        at org.jboss.resteasy.reactive.common.processor.EndpointIndexer.createResourceMethod(EndpointIndexer.java:686)
        ... 13 more

The error comes from the EndpointIndexer class:

quarkus/independent-projects/resteasy-reactive/common/processor/src/main/java/org/jboss/resteasy/reactive/common/processor/EndpointIndexer.java

Line 688 in 46892f9

"'@FormParam' and '@RestForm' can only be used on methods annotated with '@Consumes(MediaType.MULTIPART_FORM_DATA)' '@Consumes(MediaType.APPLICATION_FORM_URLENCODED)'. Offending method is "

To temporary fix the Gradle build error, you could try to remove the 4 @FormParam annotations from the Owner class (but it breaks later the UI on the Owner update screen)

How to Reproduce?

Clone and build the quarkus-spring-petclinic project:

2. git clone https://github.com/spring-petclinic/quarkus-spring-petclinic.git
3. ./gradlew --console=plain quarkusDev

Additional information

I hope this problem is not due to an error in my use of Quarkus.

Thanks for reporting!

Can you please provide the instruction I can use to reproduce the problem?

[arey]

Sure @geoand I've gave them in the How to Reproduce? section. You need to clone the https://github.com/spring-petclinic/quarkus-spring-petclinic.git repository and then run the gradle build. It should fail.
You can compare the Maven build that succeeds.

[geoand]

This happens in the Gradle version and not the Maven version because of the presense of implementation 'io.quarkus:quarkus-spring-data-rest in the former and not the latter.

@arey btw, this is an interesting project. Would you be interested in sharing your story at some point?
