This Pipeline builds the application, runs unit as well as integration tests and deploys the application to several environments. It uses a global variable "deploy" that is provided within a Shared Library. The deploy method copies the JAR-File to a remote server and starts the application. Through the handy REST endpoints of Spring Boot Actuator a previous version of the application is stopped beforehand. Afterwards the deployment is verified via the health status monitor of the application.
