ERROR:Missing dependency hippo-repository

we’re trying to add custom validator following documentation here: (v13.3.0) https://documentation.bloomreach.com/library/concepts/plugins/create-a-custom-field-validator.html

Added following dependency to pom file to extend custom validator from “org.onehippo.cms.services.validation.api.Validator” :

 <dependency>
          <groupId>org.onehippo.cms7</groupId>
          <artifactId>hippo-services-validation</artifactId>
      </dependency>

Following that the code was able compile just fine, but throws the missing dependency error upon server start:

[ **INFO** ] [talledLocalContainer] 24.09.2019 23:14:33 ERROR main [RepositoryServlet.init:246] Error while setting up JCR repository: 

[ **INFO** ] [talledLocalContainer] javax.jcr.RepositoryException: unchecked exception: org.onehippo.cm.model.impl.exceptions.MissingDependencyException: Project 'hippo-services-validation' has a missing dependency 'hippo-repository'

[ **INFO** ] [talledLocalContainer] Caused by: org.onehippo.cm.model.impl.exceptions.MissingDependencyException: Project 'hippo-services-validation' has a missing dependency 'hippo-repository'

How can we resolve the missing dependency ?
