Failed to read candidate component class when testing Spring Data Repository – IndexOutOfBoundsException

I’m trying to test a Spring Data JPA repository but when I run the test I always get the following error

The class it talks about is a pretty simple entity

@Entity
@Table(name = Analyse.Table.NAME)
public class Analyse implements IPrimaryKey, IAdaptable {
...
}

If I comment the @Table annotation I get the same error on the next class.

I also had the issue on a classe with @Cacheable and it gave me another error

I’ve checked my dependencies but I haven’t found anything too weird.

Answer

Okay, so after 4 hours of research I found the issue.

The thing is, on my project we are using EclipseLink as JPA provider and not hibernate.

Our app has several modules, and I was working on the data access module which has no tests at all yet.

We have a main module which configures a lot of things and launch the webapp.

The issue was that I depended on the wrong eclipselink artifact, I had a dependency on

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>eclipselink</artifactId>
            <version>${eclipse-link-version}</version>
        </dependency>

instead of

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>org.eclipse.persistence.jpa</artifactId>
            <version>${eclipse-link-version}</version>
        </dependency>

With the latter, it works fine !
