Upgrading to Quarkus 3: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlElement

[bcluap]

Hi,

I'm busy upgrading to Quarkus 3 from the latest version 2 release. I've got everything compiled now but get this when trying to boot Quarkus:

2023-03-31 16:45:35,485  ERROR io.qua.run.Application:run (main) Failed to start application (with profile [prod]): java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlElement

None of my code uses javax.xml.bind.annotation.XmlElement but I assume a transient dependency does. Any ideas how to debug this and see whats dragging that in?

Thanks

Hey,

I have a similar problem. I get the following:

it looks similar and I found this related bug on git hub. Is anybody able to provide some help here?

#27065

Okay - I found my solution.

I did the following at some point in my code with one ObjectMapper:

 ObjectMapper mapper = new ObjectMapper();
 mapper.findAndRegisterModules();

I just needed this though:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());

I think because jackson has backwards compatibility with old namespaces and when you register everything, you are also registering the module with the old javax namespace. I think as soon as you register the explicit modules it will just work. Not sure if it solves your problem as well.

Encounter the same issue.

In my project, I add jackson module com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider.
This module depends other version of xml library. Remove jackson module solve the problem.

You can list your project dependencies to find whether there is xml dependency conflict

We recommend using quarkus update to update to Quarkus 3.

In particular, it will replace the Jackson dependencies with their Jakarta EE 10 counterparts, which seems to be one of the problems here.
