1) Edit the json file representing your entity (add/remove field, the syntax is pretty easy, check in the end of the file if is required any change to the general entity properties like ‘fieldsContainOneToMany’…), you’ll find it in:
<jhipster_root_folder>/.jhipster/entityName.json
2) Build the code.
3) In the root of your project run the command:
yo jhipster:entity entityName
NOTE: this command by default overwrite all your manual changes. I recommend to do a commit on a VCS repository before to run this command to eventually revert any not required change.
4) run
mvn liquibase:diff
