Keycloak 22.0.4 custom SPI that depedends on resteasy does not work

[xsajkha]

Describe the bug

I adding two custom adapters (UserStorageProvider & IdentityProvider). I'm using resteasy(version 6.2.4.Final) rest clients to integrate with external rest services. I have added the jboss resteasy dependencies at compile scope. When I try to build the keycloak with kc.sh build I am getting following error:

ERROR: io.quarkus.builder.BuildException: Build failure: Build failed due to errors Oct 17 13:08:46 mba-t1-websso1 kc.sh: [error]: Build step io.quarkus.resteasy.deployment.ResteasyStandaloneBuildStep#staticInit threw an exception: java.lang.LinkageError: loader constraint violation: loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @54afd745 wants to load interface org.jboss.resteasy.spi.ResteasyDeployment. A different interface with the same name was previously loaded by java.net.URLClassLoader @f99f5e0. (org.jboss.resteasy.spi.ResteasyDeployment is in unnamed module of loader java.net.URLClassLoader @f99f5e0, parent loader 'app')
I have added the file named: jakarta.ws.rs.ext.Providers file under META-INF >services folder and it contains the ref of the class org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider
Also I have two other files places under services folder for IdentityProviderFactor and UserStorageProviderFactory pointing to my custom providers.

My pom looks like:
