@Modifing not supported by vavr integration

[jbochard]

I'm working with spring-boot 2.3.5.RELEASE and vavr 0.10.3 and I have this error when I try to invoke the method disableEnabledCredentials() defined in this way:

public interface ICredentialDAO extends Repository<Credential, String> {

    @Modifying
    @Query("update Credential d set d.enabled = false where d.enabled = true")
    Try<Integer> disableEnabledCredentials();

    Option<Credential> findByEnabled(boolean enabled);

    Try<Credential> save(Credential credential);

}

Error: "Modifying queries can only use void or int/Integer as return type!"; nested exception is java.lang.IllegalArgumentException: Modifying queries can only use void or int/Integer as return type!

I know that vavr is supported by spring-data-jpa because I has using this features in other methods as findByEnabled() or save().

The support by vavr should't include @Modifying allowing return of Try or Try?

My pom includes:

Spring Framework provides some support around Vavr's Try (see #20361) but the problem you're seeing is probably related to Spring Data Commons' support. This was added in DATACMNS-983, but I haven't found any mention of @Modifying nor know enough about this subject to help here.

Could you create a new issue in the Spring Data Commons project please?

Thanks!
