Using Hydra Package

I am trying to use Hydra package to create a local package for a cohort but I keep getting the error below. I copied the pom.xml from the GitHub repo to the hydra package and tried to specify the Skelton path and still no luck. Any tips how do run the package? Apologize if this is a simple question.


  • specifications=T2D_json,
  • outputFolder=“T2DHydraOutput”,
  • packageName = “T2DCohort”
  • )
    Error in .jcall(“RJavaTools”, “Ljava/lang/Object;”, “invokeMethod”, cl, :
    java.lang.RuntimeException: org.json.JSONException: JSONObject[“skeletonType”] not found.
    In addition: Warning message:
