Running a custom JavaScript task in the backend Marklogic server

Question

I'm trying to get all the collection list in datahub-staging from the backend server by runnng a gradle task.

I tried writing a below task:

cat myCustomJs.task 
task myJavascriptTask(type: com.marklogic.gradle.task.ServerEvalTask) {
  javascript = "cts.collections()"
}

But, I'm not sure how to create or run the task so that I can get the result of cts.collections(). Any leads on this is much appreciated.

I have a several tasks like this set up in my build.gradle file. Here's the pattern you're looking for:

task getCollections(type: com.marklogic.gradle.task.MarkLogicTask) {
  doLast {
    def client = getAppConfig().newDatabaseClient()
    String request = """
      cts.collections().toArray().join("; ")
    """;

    try {
      String result
      result = client.newServerEval().javascript(request).evalAs(String.class);
      if (result != null) {
        println result
      }
    } finally {
      client.release()
    }
  }
}
