DeploymentException: Mixing RESTEasy Reactive and RESTEasy Classic server parts is not supported

[daloji]

Describe the bug

Hello
I'm trying to upgrade our quarkus version (3.2.9 -> 3.5) but I have a problem.
[ERROR] [error]: Build step io.quarkus.resteasy.reactive.common.deployment.ResteasyReactiveCommonProcessor#checkMixingStacks threw an exception: jakarta.enterprise.inject.spi.DeploymentException: Mixing RESTEasy Reactive and RESTEasy Classic server parts is not supported

we have migrated our lib ReastEasy-classic to RestEasy Reactive

 <dependency>
 <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy-reactive</artifactId>
    </dependency>
 <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy-reactive-jsonb</artifactId>
    </dependency>
 <dependency>
<dependency>
      <groupId>org.jboss.resteasy</groupId>
      <artifactId>resteasy-multipart-provider</artifactId>
    </dependency> 

I think the issue is from resteasy-multipart-provider I haven't found an Reactive equivalent

Expected behavior

support upgrading 3.2.9 to 3.5 with resteasy-multipart-provider dependency

Actual behavior

[error]: Build step io.quarkus.resteasy.reactive.common.deployment.ResteasyReactiveCommonProcessor#checkMixingStacks threw an exception: jakarta.enterprise.inject.spi.DeploymentException: Mixing RESTEasy Reactive and RESTEasy Classic server parts is not supported at io.quarkus.resteasy.reactive.common.deployment.ResteasyReactiveCommonProcessor.checkMixingStacks(ResteasyReactiveCommonProcessor.java:107) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104) at java.base/java.lang.reflect.Method.invoke(Method.java:578) at io.quarkus.deployment.ExtensionLoader$3.execute(ExtensionLoader.java:849) at io.quarkus.builder.BuildContext.run(BuildContext.java:282) at org.jboss.threads.ContextHandler$1.runWith(ContextHandler.java:18) at org.jboss.threads.EnhancedQueueExecutor$Task.run(EnhancedQueueExecutor.java:2513) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1538) at java.base/java.lang.Thread.run(Thread.java:1589) at org.jboss.threads.JBossThread.run(JBossThread.java:501)

@daloji See here https://stackoverflow.com/questions/67675566/quarkus-reasteasy-reactive-with-multipart-extension

yes but we use resteasy-multipart-provider not quarkus-resteasy-multipart

[gsmet]

@daloji It's exactly the same issue. resteasy-multipart-provider is part of RESTEasy Classic and you are using RESTEasy Reactive so this is not a supported combination.
We used to not complain about it but now we complain loudly as it can lead to unexpected behavior.

You should use the multipart support of RESTEasy Reactive and report back if you encounter issues.

I assume this is the same as https://quarkusio.zulipchat.com/#narrow/stream/187030-users/topic/Mixing.20RESTEasy.20Reactive.20and.20RESTEasy.20Classic.20server.20parts/near/404032138, correct?

@geoand

yes

[geoand]

As mentioned in the chat, RESTEasy Reactive already comes with multipart support.

@geoand I'm sorry to bother you for a closed topic, but with quarkus multipart support I lost the possibility to send a generic multipart form via RR client; which is the right way to intercept a generic form on server side and send this form to a RR client?

thanks
Luca

@luca-bassoricci If I were you, I would create a small project showing what you achieved with RESTEasy Classic and can't with the Reactive one.
