Mixing RESTEasy Reactive and RESTEasy Classic server parts is not supported

Question

I have been upgrading Quarkus to 3.7.2. So while creating a build I'm getting an exception as :-

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

Couldn't find the root cause for this exception. I'm excepting the build should get successful.

You need to remove all dependencies with <groupId>org.jboss.resteasy</groupId>
