I have created a project using the aem-project-archetype-aem-project-archetype-27. I've added a package to the core module at com.myproject.core.workflows. When I check the bundle, it is marked as a private package. How do I add new packages to the default list of packages and have them published as public? I don't see a setting in the pom files that expressly set the exports. How is this handled now?
