Multi-Configuration Project: This is for projects that will be tested on "multiple environments", and require different configurations, depending on those environments. Git-Hub Organization: This type of project can use the "source control platform's organization" and allow Jenkins to act on Jenkinsfiles stored within the organization’s repositories. Folder: This provides a method to gr...
