Jenkins Role-Based Strategy Plugin; When we use a single Jenkins, we don’t want users to see or process (Build, Delete, etc.) all projects. In these cases, we can use Global Roles, but only transactions such as normal jobs and credentials, etc. can be restricted. For this reason, we can add specific patterns with the features that Role-Based plugin provides us and add them to the project-based role to the users.
