As things evolve also our project "Piper" evolves and we changed the way how we implement pipelines and how we publish examples.
You can find the Fiori UI5 pipeline here . Additional scenarios can also be found here https://sap.github.io/jenkins-library/ at the Scenarios menu.
Please open issues in future directly in https://github.com/SAP/jenkins-library/issues
In the GitHub repository of the Jenkins library you find a list of Github issues for known bugs or planned future improvements. Feel free to open new issues for feature requests, bugs or general feedback there.
