Importando arquivo JDL

É possível criar um arquivo de modelagem do JHipster (arquivo .jdl) através do JDL-Studio:

https://start.jhipster.tech/jdl-studio/

Após gerar e baixar o arquivo (geralmente será jhipster-jdl.jh), no diretório do projeto.

Executar o comando para importar as entidades (veja que o arquivo foi renomeado):

$ jhipster import-jdl ./jhipster-jdl

Rodando a aplicação

Entre no diretório da aplicação e digite:

$ mvnw

Abrir um navegador e digitar:

http://localhost:8080 (usr e pwd: admin)
