Jhipster 2.27 : can't create an entity - jhipster

Question

I have forked Jhipster 2.27 and tried to add an entity with
yo jhipster:entity car
I got this error :
events.js:154
throw er; // Unhandled 'error' event
^
TypeError: Cannot read property 'endsWith' of undefined

Any idea of what's going wrong here?
Thank you.

Answer 1

You haven't forked JHipster 2.27, you have forked JHipster 3.0
from master (2.27 is on v2.x_maintenance branch) otherwise you would have
not been proposed to generate a monolith app.
It seems you have modified manually your .yo-rc.json file as JHipster would have rejected com.myApp.testapp with this error: "The package name you have provided is not a valid Java package name."
Your .yo-rc.json file is not valid, there should not be this "testapp" section, this is why it fails.
Here is what your .yo-rc.json file should be:
{
"generator-jhipster": {
"jhipsterVersion": "2.27.0",
"baseName": "jhipster",
"packageName": "com.myapp.testapp",
"packageFolder": "com/myapp/testapp",
"authenticationType": "session",
"hibernateCache": "ehcache",
"clusteredHttpSession": "no",
"websocket": "no",
"databaseType": "sql",
"devDatabaseType": "mysql",
"prodDatabaseType": "mysql",
"searchEngine": "no",
"buildTool": "maven",
"enableSocialSignIn": false,
"rememberMeKey": "33cd878a5fc34f050fec62a1c0c3f4dafb64458e",
"useSass": false,
"applicationType": "monolith",
"testFrameworks": [
"gatling"
],
"enableTranslation": true,
"nativeLanguage": "fr",
"languages": [
"fr",
"ca"
]
}
}
Update 1
From your trace it seems that you tried to generate an app in the generator's folder, this cannot work.
Application files will be generated in folder:
/home/myUbuntu/dev/workspace/generator-jhipster-master
You got to run yo jhipster in a new empty folder.
Update 2
Your last error looks like you have changed the version of the generator in its package.json. Npm then looks up this version on nmpjs.org and cannot find it.
Update 3
Read our docs about how to use your forked generator: https://github.com/jhipster/generator-jhipster/blob/master/CONTRIBUTING.md#setup
