Error generating monolith from jdl with WebFlux and relationship to User entity

[terrytompkins]

Overview of the issue

Generate a monolith application with WebFlux enabled as an option while running jhipster in a new directory. This works without issue. Then attempt to generate entities and the associated CRUD admin pages from a JDL file which has one or more relationships (different cardinalities tried) with the special User entity. Running "jhipster jdl entity.jdl" will fail during generation of java source files. The error will be similar to this: "Error running generator entities: Error: Error parsing file src/main/java/com/acme/webfluxuserjdltest/repository/BlogRepositoryInternalImpl.java: undefined". The full text of the error is attached as hipster-jdl-error.txt

Related issues

I did not find a similar reported issue.

Suggest a Fix

I will take a look at the generator code, but I am not familiar with how this code works (yet).

I do love jHipster, and I have and will continue donating the the collective - thank you! yo-rc.json.txt

jhipster-jdl-error.txt content of error referenced above from running jhipster jdl entity.jdl

[terrytompkins]

I have narrowed the problem down to changes made to generator-jhipster between 7.3.0 and 7.3.1. The former version worked with my sample jdl, and the latter does not. I'll do a comparison between these generator versions to see if anything jumps out.

Have you had any luck figuring this out @TransWebT?

[mshima]

Looks like there is a bug at prettier-plugin-java. It’s failing to report the error location.

[terrytompkins]

@mraible - I was reviewing the relevant differences between 7.3.0 and 7.3.1 last week and then got busy with some day job work I had to catch up with. I'm planning on digging in again this weekend unless a fix jumps out at someone else. -terry

[mshima]

It's indeed a bug. The offending line is:

import .repository.rowmapper.UserRowMapper;

And prettier-plugin-java fails to identify the line. cc @clementdessoude
