[keycloak-user] Custom SPI does not appear in list

[John Norris]

Hi Stian,
if I comment out my line then keycloak starts.
if I leave my line in and comment out the line with microprofile-metrics-smallrye:2.0 and leave my line in, then it fails to start. Different error but it does not actually say anything useful
08:39:40,817 INFO  [org.jboss.as.server] (Thread-1) WFLYSRV0220: Server shutdown has been requested via an OS signal
08:39:40,859 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 65) MSC000001: Failed to start service jboss.deployment.unit."keycloak-server.war".undertow-deployment: org.jboss.msc.service.StartException in service jboss.deployment.unit."keycloak-server.war".undertow-deployment: java.lang.RuntimeException: RESTEASY003325: Failed to construct public org.keycloak.services.resources.KeycloakApplication(javax.servlet.ServletContext,org.jboss.resteasy.core.Dispatcher)

    etc etc

My standalone.xml is as installed with 6.0.1. The unchanged file works. Add my line - fails. Remove metrics-smallrye - fails.

Regards,
John

module deployment like you've done is what I referred to by the old school deployment approach. So what you're doing looks about right.

Do you only get the NPE below when you include your module? Is your standalone.xml in sync with the latest release or perhaps it's missing something?

I think I may have the same problem.
I have updated standalone.xml

    <subsystem xmlns="urn:jboss:domain:keycloak-server:1.1">
        <web-context>auth</web-context>
        <providers>
            <provider>classpath:${jboss.home.dir}/providers/*</provider>
            <!-- this is the line I have added -->
            <provider>module:org/softwarefactory/keycloak/mqtt</provider>
        </providers>

and when I run standalone.sh, I get

 16:24:40,028 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([("subsystem" => "microprofile-metrics-smallrye")]): java.lang.NullPointerException

So two questions.
Can I remove  microprofile-metrics-smallrye from standalone.xml?
What is the old school module deployment - I basically followed 6.2.2 in Server Developer docs.

John

Deployments in standalone/deployments doesn't currently support deploying
SPIs. You need to use the old-school module deployment approach for that.
