Can't use jakarta.ws.rs.client.ClientBuilder

[nicolasduminil]

Hello,

In a Quarkus 3.3.3 REST service, I need to call another external REST service using jakarta.ws.rs.client.ClientBuilder. For some reason that I won't detail here, I can't use Microprofile REST Client API. After build, in the target/quarkus-app/lib/main/ I have the file jakarta.ws.rs.jakarta.ws.rs-api.3.1.0.jar which contains the class jakarta.ws.rs.client.ClientBuilder, as shown in the attached screen copy.

However, at the runtime I get the following exception:

2023-11-24 17:41:20,187 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-1) HTTP Request to /api/be failed, error id: 643321e2-0868-468f-bd3d-244bcc451525-1: org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: java.lang.ClassNotFoundException: Provider for jakarta.ws.rs.client.ClientBuilder cannot be found

What is the provider for jakarta.ws.rs.client.ClientBuilder that I need to include in my dependencies ?

Many thanks in advance.

Kind regards,

Nicolas

From what I can see, you are using RESTEasy Classic so you would need quarkus-rest-client added as an extension.

Hello,
Yes, this solves my issue, many thanks. However, I was wondering what would happen if, instead of quarkus-rest-client I'd be using that:

    <dependency>
      <groupId>org.jboss.resteasy</groupId>
      <artifactId>resteasy-client</artifactId>
      <version>6.2.6.Final</version>
    </dependency>

Ticket may be closed.

You shouldn't do that. We have extensions for a good reason. Whenever there is an extension for your needs, better use it.
