[FIXED] CrudRepository cannot be resolved to a type

Issue

I'm working on a Spring Boot project (generated by Spring Initializr), using Maven. I want to create a CrudRepository, but I'm getting the error "CrudRepository cannot be resolved to a type" and the package org.springframework.data.repository does not contain the CrudRepository class. I tried to follow a bunch of tutorials to understand what is wrong and I didn't find anything. My POM looks right to me, I don't have any build failure when I run maven clean and package goals, I tried to update the project and download sources, but nothing works. Eclipse can't find the CrudRepository class.

Here is my POM file:

            </plugin>
        </plugins>
    </build>


</project>

And my repository:

package com.myquickstart.repositories;

import org.springframework.stereotype.Repository;
import org.springframework.data.repository.CrudRepository;
import com.myquickstart.entities.Movie;

@Repository
public interface MovieRepository extends CrudRepository<Movie, Long> {

}

Thanks for your help

Edit:

I've updated the project with the "Maven => Update project" in Eclipse. After that, I got this error in the "Problems" view:

C:/Users/carrm/.m2/repository/org/hibernate/hibernate-core/5.0.11.Final/hibernate-core-5.0.11.Final.jar' in project 'SpringQuickstart' cannot be read or is not a valid ZIP file

I'm not sure to know how to solve this/what is the link with my CrudRepository problem.

Solution

It looks like it was an issue with Maven libraries. I deleted the whole content in .m2/repository and ran Maven > Update project in Eclipse, so that Maven had to download the whole content again. No more error after this!

Edit

As pointed out by user3578953, executing maven-clean does the same thing that I did by deleting the whole m2 repository content. I didn't know much about Maven when I first asked this question, but this is obviously a better way to solve the issue.
