Issue with multiform data rest client on Quarkus 3.14

[djphatmix]

Describe the bug

I have the below rest endpoint. Whenever I start Quarkus, I get an error saying that my rest client has not been indexed at build time. I am using Quarkus 3.14.1

public class Request {
    
    @RestForm("file")
    @PartType(MediaType.APPLICATION_OCTET_STREAM)
    private InputStream file;

    @RestForm("filename")
    @PartType(MediaType.TEXT_PLAIN)
    private String filename;
}

Endpoint definition:

    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    public String upload(Request request) {
      // business logic.
        return "done";
    }

Error:
Caused by: java.lang.IllegalStateException: REST client interface: interface com.test.api.restclient.TestRestApi was not indexed at build time.

Expected behavior

The expectation is that the app should start up without any issues.

Is TestRestApi in another module?

[djphatmix]

Yes, TestRestAPI is in a different module. I did add the jandex plugin in my POM but it does not seem to make a difference.

<build>
     <plugins>
       <plugin>
         <groupId>io.smallrye</groupId>
         <artifactId>jandex-maven-plugin</artifactId>
         <version>3.1.2</version>
         <executions>
           <execution>
             <id>make-index</id>
             <goals>
               <goal>jandex</goal>
             </goals>
           </execution>
         </executions>
       </plugin>
     </plugins>
   </build>

Have you tried the META-INF/beans.xml method described here?

[djphatmix]

I did try it. So basically what we have observed is that once we remove the inputStream parameter on the Request then everything works as expected.

My issue is very similar to this one #42077.

[geoand]

Very interesting.

If you attach a sample application that exhibits the problem in action, I can do a deep dive and see what can be done.

[djphatmix]

I have created 2 projects(producer and consumer). In my consumer project, ExampleResourceTest.java fails with the below error message.

Error:
Caused by: java.lang.IllegalStateException: REST client interface: interface za.co.tutorial.StickerDefinitionRestApi was not indexed at build time. See https://quarkus.io/guides/cdi-reference#bean_discovery for information on how to index the module that contains it.

at org.jboss.resteasy.reactive.client.impl.WebTargetImpl.proxy(WebTargetImpl.java:449)
at io.quarkus.rest.client.reactive.runtime.RestClientBuilderImpl.build(RestClientBuilderImpl.java:528)

I have also attached the sample projects.
consumer.zip
producer.zip

Very interesting.

I have uploaded the two projects. The rest API is defined inside a project called sample and the failing test is defined inside the consumer project.

Thanks, I'll check soon

Your reproducer was super helpful, thanks!

#43437 fixes the issue

#43437 fixes the issue

So will the fix go into 3.14.4 or will it be part of a new patch release?

[geoand]

I will hopefully be part of 3.15.1

[djphatmix]

I will hopefully be part of 3.15.1

So what is the tentative release date for 3.15.1?

[geoand]

Towards the end of the month or beginning of October unless something unforeable happens
