I am getting the following error when starting keycloak version 25.0.0.  
ERROR: org.eclipse.microprofile.config.spi.ConfigSource: org.jboss.resteasy.microprofile.config.ServletConfigSource not a subtype

We upgraded from 12 to 25. However, our SPI was built against 10. After making several changes and building against 25, I am stuck with the above error. I fixed some other not a subtype errors by adding some more dependencies to the pom file after reading online. But, I can not find a solution for the above error. Below is what I currently have as dependencies. Can someone tell me what else I need to include or even how to begin to figure out what I might need to include?

I added the following and that helped. I think. Now I get  
ERROR: io.smallrye.config.ConfigSourceFactory: io.smallrye.config.PropertiesLocationConfigSourceFactory not a subtype

```auto
    <dependency>
      <groupId>org.jboss.resteasy.microprofile</groupId>
      <artifactId>microprofile-config</artifactId>
      <version>2.1.5.Final</version>
    </dependency>
    <dependency>
      <groupId>org.eclipse.microprofile.config</groupId>
      <artifactId>microprofile-config-api</artifactId>
      <version>3.0.3</version>
      <scope>provided</scope>
    </dependency>

```

Is there an easy way to track down the dependencies and version that I need based on the error or something?

Instead of adding more and more dependencies, perhaps a complete new rewrite of your extension based on current dependencies would be the better approach!?  
As you are comming from v10/12, this was a complete different environment than it is today…

I am starting to wonder about a complete rewrite. Although I am not sure time will allow it. And, the original developer is no longer with the company, so that doesn’t help either. I don’t mind including more dependencies if it will work.

I am now getting the following error after adding this.

```auto

I fixed the configuration validation failed error by adding the following dependencies.

```auto
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-core</artifactId>
      <version>3.8.5</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-vertx-http</artifactId>
      <version>3.8.5</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-jackson</artifactId>
      <version>3.8.5</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy-common</artifactId>
      <version>3.8.5</version>
      <scope>provided</scope>
    </dependency>

```

And now my error is.  
Caused by: java.lang.LinkageError: loader constraint violation: loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @6d0b5baf wants to load interface io.quarkus.arc.runtime.BeanContainer. A different interface with the same name was previously loaded by java.net.URLClassLoader @b83a9be. (io.quarkus.arc.runtime.BeanContainer is in unnamed module of loader java.net.URLClassLoader @b83a9be, parent loader ‘app’)

I am really starting to think I have went down the wrong path here. Looking at the current code. It seems to need jboss resteasy for HttpRequest and HttpResponse, jboss logging, fasterxml.jackson, and jarkarta.ws.rs. Should I just not be using these in the newer Keycloak, or have I really just messed up the dependencies.
