How do I get Spring Data REST 2.0 RC1 to work?

Question

I got Spring Data REST 1.1.0.M1 working, but would like to try version 2.0.

Here's my POM:

When I try SDR 2.0.0.R1, I get ClassNotFoundException: org.springframework.data.web.config.HateoasAwareSpringDataWebConfiguration and when I try HATEOAS 0.9, I get IllegalArgumentException: Content must not be a collection! Use Resources instead!

You need to upgrade to the correct set of dependency versions. If you want to upgrade to Spring Data REST 2.0, you also need to upgrade to the according versions of other Spring Data modules contained in the release train. So you'll need:

• Spring Data REST 2.0.0.RC1
• Spring Data JPA 1.5.0.RC1 (as indicated in the POM of Spring Data REST)
• Spring HATEOAS 0.9.0.RELEASE (also indicated in the POM of Spring Data REST)
