Failed to build strimzi-kafka-operator

[mqware]

Hello,

I am trying to build strimzi-kafka-operator, so I cloned the repository and ran "mvn clean" as instructed in Build and deploy Strimzi from source, but I keep getting the following error:

[ERROR] Failed to execute goal on project config-model-generator: Could not resolve dependencies for project io.strimzi:config-model-generator:jar:0.42.0-SNAPSHOT
[ERROR] dependency: io.strimzi:config-model:jar:0.42.0-SNAPSHOT (compile)
[ERROR]         Could not find artifact io.strimzi:config-model:jar:0.42.0-SNAPSHOT

I tried it multiple times both on Windows and Linux, but always with the same result. At the end I was able to get around this by extracting the config-model jar from the container, and installing it into my local Maven repository, so Maven can find it, (and switching to the release-0.41.x branch to match the version of the jar), but that's obviously a hack. Can you help me figure out what am I doing wrong here? I am not familiar with Maven, but unlike other poms, the pom.xml for config-model doesn't have a jar section, so I don't understand how that jar would be built.

Thanks in advance.

Just run something like mvn install if you just checked it out?

I tried mvn install, but that failed in test io.strimzi.test.mockkube3.MockKube3ControllersMockTest.testDeploymentController. I assume this is because something is not configured correctly in my environment. But mvn install -DskipTests worked fine. Thanks!

I am not sure what it was, but I cleaned up my Docker environment and reset Microk8s, and then the above test passed. However, now I am stuck on this one;

[ERROR] Failures:
[ERROR]   MainIT.testCreateClusterRolesCreatesClusterRoles(VertxTestContext) io.vertx.core.impl.NoStackTraceThrowable: Failed to create Cluster Roles.

I attached the test result.
Thank you.

Sounds like that expects your Kubernetes cluster to have a set default namespace which you don't have (e.g. in your .kubeconfig context):

# ...
- context:
    cluster: my-kube:6443
    namespace: myproject # <=== THSI MIGHT BE MISSING IN YOUR CONFIG
    user: kube:admin/my-kube:6443
  name: my-kube
# ...

Could you please open a bug for it? https://github.com/strimzi/strimzi-kafka-operator/issues ... I will try to have a look into it.

Actually, we do not use this feature anymore anyway. So I just removed it in #10265. So there's no need to open an issue anymore. Thanks.

I tried what you suggested, but unfortunately it didn't work. The first time I got this error:

io.fabric8.kubernetes.client.KubernetesClientException: Operation: [get]  for kind: [ClusterRole]  with name: [strimzi-kafka-broker]  in namespace: [null]  failed.

And now this:

io.fabric8.kubernetes.client.KubernetesClientException: Operation: [get]  for kind: [ClusterRole]  with name: [strimzi-kafka-broker]  in namespace: [myproject]  failed.

So, it looks like the namespace got picked up from the config, but the test still failed. Since you are removing this code anyway, I will just wait for that change.
Thanks.

That is strange. In any case, I removed it in the PR I linked, so once it is merged it should be solved.
