Jhipster: How can I only generate a back-end microservice application - jhipster

Question

I want to generate microservices application with only Back-end code.
I found solution in this.
And I used jhipster --skip-client but It's still have some Font-end files like node-modules,packege.json...
After that, I found another solution instead of jhipster --skip-client . I use jhipster:server and it works . I didn't have any Font-End file,but I could run by use mvnw . This is my error

How can I resolve my problem

Answer 1

jhipster --skip-client is the correct way to generate a server only application. By invoking jhipster server, you are using an internal "jhipster sub-generator" which will likely result in an incomplete or even non working application.
The package.json and node_modules are not frontend files. They are required to locally install jhipster as a JavaScript dependency of your project (jhipster is coded in JS). This way when invoking jhipster in your app directory, it is garanteed to use the same jhipster version as the one your app was generated with.
