Created Entity not displayed under entity menu in Angular 2

[berndwaibel]

Overview of the issue

When running the jhipster jdl generator twice, all Entities are removed on second run from Navigation bar. So the created Entites List in the generated Angular Frontend is empty.

Motivation for or Use Case

When I add new Entities, I will run the jhipster generator again to add the new entries. But he removes als entries from generated navbar.

Reproduce the error

Generate any jhipster jdl file, for example using the JDL GUI examples at (https://start.jhipster.tech/jdl-studio/). Call the file "jhipster-jdl.jdl" (name does not matter, but is following used. The file should be related to microservices, and should contain applications and entities.

I am using git bash on Windows for following commands.

1. Copy jhipster-jdl.jdl to a new folder
2. Run git init
3. Run git add jhipster-jdl.jdl
4. Run git commit -m "test"
5. Run git status (nothing should be uncommitted)
6. Run "jhipster jdl jhipster-jdl.jdl"
7. Run git status (nothing should be uncommitted)
8. Run "jhipster jdl jhipster-jdl.jdl" again. Answer "a" to regenerate all files.
9. Run "git status", and you will see changes in the generated Angular and Java and XML files.

The following files are changed: modified: testGateway/src/main/resources/config/liquibase/master.xml modified: testGateway/src/main/webapp/app/entities/entity-navbar-items.ts modified: testGateway/src/main/webapp/app/entities/entity-routing.module.ts modified: testGateway/src/main/webapp/app/layouts/navbar/navbar.component.html modified: testGateway/src/main/webapp/i18n/en/global.json modified: testService/src/main/java/de/bwaibel/test/config/CacheConfiguration.java modified: testService/src/main/resources/config/liquibase/master.xml

If you use " jhipster jdl --ignore-application jhipster-jdl.jdl" instead, no error happens, as nothing will be regenerated.

If you use "jhipster jdl jhipster-jdl.jdl", all entities are removed from applications.

Suggest a Fix

When running the jdl generator twice, and applicaton and entities exists already, do not regenerate the components listed above. Or regenerate the entites too.

Browsers and Operating System

Windows 10, all browser behave the same (as the source code is missing the entities).

To regenerate with entities you need --with-entities option.

I confirm having the same issue. If you generate entities from jdl twice without any modification the second time it will :

• remove entities from entity-navbar-items.ts
• remove entities from entity-routing.module.ts
• remove items from navbar.component.html
• remove key from i18n files

But if you generate entities from jdl a second time with a new entity in the jdl :

• no problem, the new entity will be added to every of theses files, without any deletion

I did my tests in an existing project so if you do not succeed to reproduce it I can try in a brand new project to give additional information.

Command used : jhipster jdl example.jdl During generation, all files are overriden when it was asked
