JAX-RS: "RESTEASY002005: Failed executing GET org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure

I have created a simple service that enables me to listen to incoming REST requests and then perform a task and return the output of the task back to the caller as a custom object (MyObject).

This service runs perfectly fine while I execute it from IntelliJ [i am assuming the jaxrs jar are being loaded from InteliJ's internal repository] but fails when i execute the jar from command line. The exception is as follows:

[ERROR] RESTEASY002005: Failed executing GET /myapp/getVal

My REST API code is a follows:

@Path("/myapp")
@Singleton
public class MyResource {
@GET
@Path("/getVal")
@Produces(MediaType.APPLICATION_JSON)
public MyObject getVal(@QueryParam("id") @NonNull String id) throws Exception {
try {
return getMyObjData(id);
} catch(IllegalArgumentException e) {
throw new Exception(e.getMessage());
}
}
}

I have gone through a couple of links with similar issues but none helped me. For example:

https://stackoverflow.com/questions/19089781/resteasy-could-not-find-messagebodywriter-for-response-object-of-type-java-uti

https://stackoverflow.com/questions/43833220/get-request-fails-with-jax-rs-could-not-find-messagebodywriter-for-response-obj

https://stackoverflow.com/questions/52807266/simple-example-using-resteasy-jaxrs-not-working

Based on my debugging with IntelliJ and by running the jar on command line, it appears to me that the jar I am trying to build does not have the dependency of jaxrs (if I am not mistaken) even though I have added them onto my pom. I therefore, am unsure how to proceed with this issue. Can someone help me out with this?

Update:

As per the comment I have updated my parent and child pom as below:

Even after the above set of changes, I still see the same error.

The problem is similar to this one with Jersey where the services files (used to autoregister providers) are excluded from the fat jar built with the maven-assembly-plugin. The solution is to use the maven-shade-plugin, which has a transformer to concatenate the contents of all the services files into one file for the one single uber jar.

After a couple of hours of debugging, I was able to find where the issue was. As can be seen in the pom files above, I am making use of Google Guice for DI.
While using Guice, we need to bind JacksonProvider as shown below:

bind(JacksonJsonProvider.class)

The reason why it was working for me on my IDE was because the IDE was loading the necessary dependency from its local repository (classpath).

This fixed the issue for me.
