Wildfly 15.0.1 Final: Microprofile rest client - redeployment WELD-001414: Bean name is ambiguous.

[andrej.petras]

Hi,

I am trying the microprofile rest client on the Wildfly 15.0.1.Final. I did not find the documentation or how to. Is there any documentation for wildfly?

These are my steps and errors:

I need to add the dependency to the module org.eclipse.microprofile.restclient to my manifest. Without this I get class org.eclipse.microprofile.rest.client.RestClientBuilder not found.

I think this is not correct because this module is private module of the Wildfly.

<manifestEntries>
    <Dependencies>org.eclipse.microprofile.restclient</Dependencies>
</manifestEntries>

After this I was able to deploy the application and use the rest client via RestClientBuilder or @RestClient CDI integration.

But when I redeploy the running application on the server I get this error:

09:35:25,936 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC000001: Failed to start service jboss.deployment.unit."mp-client-1.0.0-SNAPSHOT.war".WeldStartService: org.jboss.msc.service.StartException in service jboss.deployment.unit."mp-client-1.0.0-SNAPSHOT.war".WeldStartService: Failed to start service

Did I am miss something in the configuration of the Server, CDI or Microprofile rest client?

Thanks!

I created simple example application to reproduce this error.

How to reproduce this error on the Widlfly 15:

1. start the server

2. mvn clean install

3. copy the mp-client-1.0.0-SNAPSHOT.war in the deployments directory.

4. run rest client

     4.1 With CDI: curl http://localhost:8080/mp-client/test/1

     4.2 Without CDI: curl http://localhost:8080/mp-client/test/2

5. rebuild and redeploy the application on running server (see step 2 and 3)
