Generator-jhipster: Problems importing JDL

Created on 26 Jan 2017 · 8Comments · Source: jhipster/generator-jhipster

Overview of the issue

I'm trying to import a "jh" file. I'm using jdl studio, and I'm using the default template downloaded from the jdl studio web page.

Motivation for or Use Case

I'm starting with the project and it's my first example.

Reproduce the error

Go to https://jhipster.github.io/jdl-studio/ and download the file (without touching the code).
Create a folder "v2".
Run yo jhipster:import-jdl jhipster-jdl.jh and the error appears:

The jdl is being parsed.
{ name: 'NullPointerException',
message: 'The parsed JDL content and the database type must be passed.',

ERROR!
Error while parsing entities from JDL

Suggest a Fix

Just fix it!

JHipster Version(s)

java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b15, mixed mode)

git version 2.9.0.windows.1

node: v6.3.0

npm: 3.10.3

bower: 1.8.0

gulp:
[11:38:55] CLI version 1.2.2

yeoman: 1.8.5

Docker version 1.12.3, build 6b644ec

docker-compose version 1.8.1, build 004ddae

JHipster version is the latest one... I think 3.12.2.

JHipster configuration, a `.yo-rc.json` file generated in the root folder

I don't have this file because the importation is not working.

Entity configuration(s) `entityName.json` files generated in the `.jhipster` directory

I don't have this file because the importation is not working.

Browsers and Operating System

I'm using windows 10 pro.

@juandavidgc did you run yo jhipster before trying to import the file ? Then you should have a .yo-rc.json
Also, please be more respectful about our work ("Just fix it!", really ?)

I had a similar issue. While importing a jdl from jdl studio, throws me the same error:

message: 'The parsed JDL content and the database type must be passed.'

my .yo-rc.json

{
  "generator-jhipster": {
    "clientFramework": "angular1",
    "useSass": false,
    "clientPackageManager": "yarn",
    "jhipsterVersion": "4.5.2",

    "baseName": "receta",
    "testFrameworks": [],

  }
}

Hello, I see that this issue was closed in January then assigned in October. Is it re-opened ?
I'm asking as I'm experiencing a similar (perhaps the same) problem and am wondering if I should open a new issue or wait until this one is resolved.
My .yo-rc.json doesn't differ much from deathrix's :

{
  "generator-jhipster": {
    "promptValues": {
      "packageName": "com.mycompany.myapp"
    },
    "jhipsterVersion": "4.9.0",

    "packageName": "com.mycompany.myapp",
    "packageFolder": "com/mycompany/myapp",
    "serverPort": "8080",
    "authenticationType": "jwt",
    "hibernateCache": "no",
    "clusteredHttpSession": false,
    "websocket": false,
    "databaseType": "mongodb",
    "devDatabaseType": "mongodb",
    "prodDatabaseType": "mongodb",
    "searchEngine": false,
    "messageBroker": false,
    "serviceDiscoveryType": false,
    "buildTool": "gradle",
    "enableSocialSignIn": false,
    "enableSwaggerCodegen": false,
    "jwtSecretKey": "da534e639a0ea6945da12faf8ce19778b416eac2",

  }
}
