Resolving Spring's data error message "Cannot resolve the name to a(n) 'element declaration"

While working on a project combining Spring Data JPA and Spring Data MongoDB I run into a lot of trouble when I introduced the

1 2 3 4 5 6 7 8

<!--xml version="1.0" encoding="UTF-8"?--> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd   http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.1.xsd">     <jpa:repositories base-package="tv.arte.tvguide.core.dao.jpa.repositories">   </jpa:repositories></beans>

The error message :

1	Cannot resolve the name to a(n) 'element declaration

I spent some time looking for the cause, and then I realised that the version of SpringDataMongoDB and SpringDataJPA had dependencies on different versions of SpringDataCore. and it was causing trouble

So if you get the same error just check your maven dependency hierarchy or go check the POM files for the libraries.

You can check out the POM files in Spring's repo :
