Quarkus: Spring Data Repository with nested camel-case properties does not work with Quarkus

[renegrob]

Describe the bug
If a repository method addresses a nested entities Quarkus cannot parse the method.

Given the follwing JPA entities:

@Entity
@Table(name = "RACE_TEAMS")
public class RaceTeamEntity {

    @Id
    @Column(name = "ID", length = 26)
    private String id;

    @Column(name = "NAME", nullable = false, length = 256)
    private String name;
    ...
}

@Entity
@Table(name = "RACE_CAR_DRIVERS")
public class RaceCarDriverEntity {

    @Id
    @Column(name = "ID", length = 26)
    private String id;

    @ManyToOne
    @JoinColumn(name = "RACE_TEAM_ID", nullable = false)
    private RaceTeamEntity team;

    @Column(name = "NAME", nullable = false, length = 256)
    private String name;
}

@Entity
@Table(name = "CLASSIC_CARS")
public class ClassicCarEntity {

    @Id
    @Column(name = "CLASSIC_CAR_ID", length = 26)
    private String id;

    @ManyToOne
    @JoinColumn(name = "BRAND_ID", nullable = false)
    private CarBrandEnity carBrand;

    @ManyToOne
    @JoinColumn(name = "DRIVER_ID", nullable = false)
    private RaceCarDriverEntity driver;

    @Column(name = "NAME", nullable = false, length = 256)
    private String name;
}

The repository method findByRaceCarDriverTeamName should find the RaceCarEntity by the Name of the Driver's RaceTeam

@Repository
public interface ClassicCarRepository extends JpaRepository<ClassicCarEntity, String> {
    List<ClassicCarEntity> findByRaceCarDriverTeamName(String teamName);
}

But instead throws UableToParseMethodException: Entity org.acme.resteasy.entities.ClassicCarEntity does not contain a field named: raceCarDriverTeamName. Offending method is findByRaceCarDriverTeamName

Expected behavior
Camel-case properties can be used as in Spring Data and sub-properties are correctly matched (e.g. the expression tomatoSpagettiSauceColor could mean tomato.spagehtti.sauce.color or tomatoSpaghetti.sauce.color or tomatoSpaghetti.sauceColor or tomato.spaghetti.sauceColor or tomato.spaghettiSauce.coloror ...)

See https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods.query-property-expressions

Actual behavior
An UnableToParseMethodExceptionis thrown if nested camel-case property address sub-entities.

To Reproduce

Checkout https://github.com/renegrob/spring-data-jpa-repo-method-issue

Steps to reproduce the behavior:

1. Execute ./mvnw compile quarkus:dev on the command line

Error in the console output:

2020-11-02 16:33:45,534 ERROR [io.qua.dep.dev.IsolatedDevModeMain] (main) Failed to start quarkus: java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors

Offending method is findByRaceCarDriverTeamName

@aureamunoz would you like to take a look at this one?

[aureamunoz]

Yep! will do

[geoand]

Thanks!

[renegrob]

I solved the issue in my fork: https://github.com/renegrob/quarkus/tree/quarkus-issue-13067. Shall I create a draft pull request?

[geoand]

Sure thing!

Please ping myself and @aureamunoz on the PR because AFAIK she was planning on working on it as well.

[renegrob]

@geoand @aureamunoz I pushed the pull request. On my fork the pipeline is not completely green but the errors don't seem to be related to the commit. I didn't add additional tests so far.
