java.lang.NoClassDefFoundError: com/palantir/roboslack/clients/SlackClients when depending on roboslack-webhook 1.1.0

[elektron9]

Try depending on roboslack-webhook 1.1.0 and running this sample code:

public static void main(String[] args) {

  WebHookToken token = WebHookToken.fromEnvironment();

 MessageRequest msg = MessageRequest.builder()
                .username("Slack Oncall Service")
                .iconEmoji(SlackMarkdown.EMOJI.decorate("sos"))
                .channel("slack-dev-msgs")
                .text("[CRITICAL] Error Logged in MailService - " + SlackMarkdown.LINK.decorate(url
                        ("https://localhost:9600/?pretty"), "[Logstash Link]"))
                .build();
        ResponseCode code = SlackWebHookService.with(token).sendMessage(msg);

        System.out.println(code);

}

We receive this error message:

Yeah, when testing the publication locally it seems like it's not picking up the compiled dependencies:

./gradlew publishNebulaPublicationToMavenLocal

Then in ~/.m2/repository/com/palantir/roboslack/roboslack-webhook/1.1.0 ->

 ❯ jar xvf roboslack-webhook-1.1.0.jar | less
