Quarkus dev mode is not working with a certain type of folder tree due to dependency injection

[jakwarrior]

Describe the bug

I found a very odd bug. I have a multimodule project and I use maven. I have 2 modules, A and B, with B depending on A. A contains a @ApplicationScoped annotated bean.

If I use this tree, everything is fine:

- pom.xml
- A folder
   - pom.xml
- B folder
  - pom.xml

But if I use this tree, the quarkus dev mode is not working:

- parent folder
   - pom.xml
- A folder
   - pom.xml
- B folder
  - pom.xml

There is a UnsatisfiedResolutionException, the bean from A is not found. But the project is still working if I use the command "java -jar quarkus-run.jar, it's only in dev mode.

Expected behavior

The dev mode should be working for every kind of tree.

Actual behavior

How to Reproduce?

I created a small project to reproduce the problem:
https://github.com/jakwarrior/quarkus-2-multi-module-project-quickstart

The main branch is working. You can use mvn quarkus:dev in the root of the project and everything is fine.
You can see the problem with the branch named "not_working". Go to the "quickstart-parent" folder and do mvn quarkus:dev. You will see this stacktrace:

I'm not quite sure if this is a supported use case but in any case if you run mvn quarkus:dev in the quickstart-rest module (which is the quarkus app itself) then it seems to work fine.

It does look like a bug, I'll look into it.

I'm not quite sure if this is a supported use case but in any case if you run mvn quarkus:dev in the quickstart-rest module (which is the quarkus app itself) then it seems to work fine.

It's working only if I do a mvn install before. Otherwise, the dependency to quickstart-core is not found.
In that case, on every change to the quickstart-core module, I need to install again the dependency and relaunch the server. We lose all the interest of the live reload of the dev mode.

@jakwarrior I opened a PR to fix the issue. A few notes on the reproducer: it looks like a mix of an older Quarkus project config using the universe BOM and the quarkus-plugin.version property and the recent one. I'd recommend removing the universe BOM which was deprecated a long time ago.
I tested your project with the upcoming 3.0 and it didn't work even after migrating to the jakarta packages. Not sure why but the compiled UserService still used the javax package for the ApplicationScoped annotation. I was wondering whether it's related to lombok but not sure.

[aloubyansky]

I meant the TestService in the previous comment, not the UserService

[jakwarrior]

@aloubyansky thanks for the PR. I forked an old project, I must have missed something while updating it. What is the correct package for the ApplicationScoped annotation ?

[aloubyansky]

The package is correct for Quarkus 2.16 that you are using. However, Quarkus 3.x is moving to Jakarta API. Here is a diff for your reproducer generated by running

mvn io.quarkus:quarkus-maven-plugin:3.0.0.Final:update -Dstream=3.0

Ah, it worked with the proper update that I posted above. I didn't do

     <dependency>
       <groupId>jakarta.enterprise</groupId>
       <artifactId>jakarta.enterprise.cdi-api</artifactId>
-      <version>2.0.2</version>
+      <version>4.0.1</version>
     </dependency>

previously, which you don't have to provide a version for, since it's managed by the quarkus-bom already. As well as junit.
