Dependencies not picked up

Expected Behavior

The Kubernetes Service Discovery should work correctly

Actual Behaviour

My Maven Project has

    <dependency>
      <groupId>io.micronaut.kubernetes</groupId>
      <artifactId>micronaut-kubernetes-discovery-client</artifactId>
      <scope>compile</scope>
    </dependency>

But the service discovery does not work:

io.micronaut.discovery.exceptions.NoAvailableServiceException: No available services for ID: [REDACTED].
Service name is correct and my pod has access to the service API.

When I try to inject a DiscoveryClient, the discovery client (which is DefaultCompositeDiscoveryClient) is empty, i.e. it has no other Discovery Clients.

When injecting a KubernetesDiscoveryClient, it fails to do so.
The deployed jar contains KubernetesDiscoveryClient.class

It works on an empty demo kubernetes-discovery project. The demo only has the aforementioned dependency.

Can you add the following line to your logback.xml file

<logger name="io.micronaut.context" level="DEBUG"/>

restart the service and then search your logged messages by KubernetesDiscoveryClient. There should be something like

09:30:47.163 [example-client] [main] DEBUG i.m.context.condition.Condition - Bean [Definition: io.micronaut.kubernetes.discovery.KubernetesDiscoveryClient] will not be loaded due to failing conditions:
09:30:47.163 [example-client] [main] DEBUG i.m.context.condition.Condition - * None of the required environments [k8s] are active: []

if KubernetesDiscoveryClient is not loaded

[Raildex]

I dont have this particular log entry, but the environment is correct.

...
Established active environments: [k8s, cloud, KUBERNETES]
...
Finding candidate beans for type: DiscoveryClient
class io.micronaut.discovery.DefaultCompositeDiscoveryClient null Definition: io.micronaut.discovery.DefaultCompositeDiscoveryClient

[msupic]

Could you please create a simple app that can be used to reproduce the issue?
