Jackson and JSONB in the same project

[ctron]

Assuming I have (because legacy) both jackson and JSONB in my quarkus application.

How can I configure a specific reactive REST client to use Jackson over JSONB?

/cc @geoand(jackson), @gsmet(jackson)

There is currently no way to do this.

I also had this problem (which, as it turns out, is actually more of a openapi-generator-maven-plugin problem in my case), so I'm happy to share information if anyone is in the same boat.

We're using jackson right now and I wanted to generate a microprofile client using the openapi-generator-maven-plugin. Unfortunately this can only generate microprofile clients with json-b as of now, so my first approach was to include both jackson and json-b in our quarkus project.

Mixing 2 things that do the same is never a good idea and I wouldn't mind it we keep only jackson - and as far as I understood, quarkus also prefers jackson over json-b (is this still true?)

Anyway, I managed to workaround this by separately generating models and APIs (thanks to @plevart comment) and this seems to do the trick.

<generatorName>java</generatorName>
<library>native</library>
<generateApis>false</generateApis>

and

<generatorName>java</generatorName>
<library>microprofile</library>
<generateModels>false</generateModels>
