Make sure you have configured the Context-Aware Configuration bnd plugin in your pom hierarchy - or inherit from io.wcm.maven:io.wcm.maven.global-parent where it is already configured.
Additionally update all other wcm.io Bundles to the latest version - in most cases this involves an update of the major version from 0.x to 1.x. In case of AEM Mocks update to the latest 1.x version for AEM 6.2, and to the latest 2.x version if you are using AEM 6.2 or higher.
