I have generated an app server only through jhipster using only.
yo jhipster --skip-client
It had generated all the necessary api calls I needed however upon accessing
http://localhost:8080/swagger-ui/index.html
I ended on a 404. I was under the impression that swagger is included however it cant seem to be accessed, although the swagger api endpoints is available.
You can't since you are only generating the rest apis. if you want to see the api-docs follow the instructions mentioned here
Once you have succesfully cloned the said repository
open dist/index.html and simply paste the source there
