Dependency class not found when loading from target/classes

[zluiten]

First of all. I'm not a very experienced java developer. This might be something very obvious :)

I'm working on a slightly modified version of https://github.com/aznamier/keycloak-event-listener-rabbitmq/ and adding a test for it using test containers (namespace has changed from com.github.aznamier to com.awareways.keycloak).

Now, when running the test, keycloak fails to start

Now the KeycloakContainer is configured like this:

    @Container
    private final KeycloakContainer keycloak = new KeycloakContainer()
            .withEnv("KK_TO_RMQ_URL", "rabbitmq")
            .withEnv("KK_TO_RMQ_USER", "guest")
            .withEnv("KK_TO_RMQ_PASSWORD", "guest")
            .withEnv("KK_TO_RMQ_EXCHANGE", "events")
            .withRealmImportFile("integration-test.json")
            .withDefaultProviderClasses()
            .withVerboseOutput()
            .withNetwork(network)
            .dependsOn(rabbitmq);

So, this project has a dependency on com.rabbitmq.amqp-client, but apparently the dependency classes are not part of the target/classes directory and I fail to find out how to do that. What am I overlooking?

Oh, there is section in the readme about dependencies... I'll try something with that!

Edit:

Yes. Fixed by specifying additional libs

        .withProviderLibsFrom(
            Maven.resolver()
                .loadPomFromFile("./pom.xml")
                .resolve("com.rabbitmq:amqp-client")
                .withoutTransitivity().asList(File.class)
        )
