Quarkus Extension as Part of a Project inside a Monorepo?

[skurfuerst]

Hey everybody,

I am currently getting my feet wet with Quarkus for the first time - and it is really a great product with an awesome dev experience.

One thing where I am currently struggling is that I'd love to experiment more with Quarkus extensions and the build-time code analysis capabilities. However, I'd love a tight dev loop, almost as tight as I get it running quarkus dev - that's why, if possible, I'd love to have the extension's code as part of my project as well, to be able to access the compile time code generation stuff.

Is there any way to make this work? In the docs, it says "you need to publish your extension to the local maven registry before using it", but I feel this would very much complicate my use case.

Thanks for any hints and all the best :)
Sebastian

You can't unfortunately develop extensions with same speed as apps on top extensions if that is what you are asking for ?

Hey,

Thanks for your quick reply!

So I would be interested in two things:

• is it possible to add some kind of deployment module to the current quarkus app? Like putting deployment sources into a new source directory or so :) it is clear for me that code changes in there need a full rebuild
• how are others developing quarkus extensions workflow wise with a manageable dev roundtrip time?

Thanks so much :)

All the best,
Sebastian

I'm actually on PTO so can't digg more atm. Maybe @aloubyansky has some tips?

Extension modules can be included in the codebase with the app. But live reload won't be working for extension modules and their deps, there will be warning logged about that.

Hi, @aloubyansky
this is composite build (included build) and it's almost always used when we want to include an external project and not really a submodule!

i recently configured a monorepo pretty much like the example you provided but i couldn't include the extension in my consumer service using regular implementation(project(":library:extension-A"))

is there any resource that i can look into why this is not possible?

[aloubyansky]

@nort3x would you be able to share a reproducer? That could make it easier to investigate and create a proper test. Thanks.

here is an example, containing 1 quarkus extension (called quarkus-base)
one generic library (common-kotlin)
one service (serivce-a)

service-a uses both of the libraries,
quarkus-base should configure jackson for service-a and provide a FeatureBuildItem (both will produce log)
i'm migrating from includedBuilds to direct includes and i can't resolve this,
i'm also providing testFixture for service-a through quarkus-base (for instance some configuration for restassured)

@nort3x could you please also create a github issue for it? Thanks.
