Hibernate validation for multi module case: javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint

See original GitHub issue

When using hibernate validation and @Valid with request body parameter, I got an 500 when Pojo I am validating is not in a module that Quarkus scans. My Pojo class has annotation @NotBlank but I get:

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'javax.validation.constraints.NotBlank' validating type 'java.lang.String'. Check configuration for 'hello.arg0.value'

If I add @NotBlank anywhere in module that Quarkus scans it works ok and pojo gets validated and I get 400 if it is invalid or 200 if it is valid.

I don’t want that my lib module is scanned, since there are a lot of things in there.

Expected behavior Pojo is validated normally, I get 400 if it is not valid or 200 if it is valid.

Actual behavior javax.validation.UnexpectedTypeException is thrown.

To Reproduce

git clone https://github.com/asodja/quarkus-multimodule-hibernate
Run MyResourceTest.java -> both tests fail, response is 500
Uncomment dummy method with @NotBlank annotation in MyResource.java
Run MyResourceTest.java -> both tests pass, response is 400 and 200 as expected

Environment (please complete the following information):

Output of java -version: openjdk version “1.8.0_242”
Quarkus version: 1.9.2.Final
Build tool: Gradle 6.6.1

Frankly, just add the Jandex index creation to your build. Anything else will be brittle.

Make sure you really have a Jandex index for the modules in which the constraints are.

Because we take the list of constraints we detect in the Jandex index and we push it to HV. Any constraint that is not in the Jandex index won’t have its validators registered in HV. Which would lead to the errors you are seeing.

@gsmet https://github.com/gsmet I am, yes, I haven’t changed anything. But while building a small, separate reproducer I noticed that it actually works as expected so it looks like there’s something wrong with my actual project. Happily (or sadly…) I only have to figure out what.

Thanks for the fast reply!
