Practically speaking, all of the real work done by a Pipeline will be wrapped As the name implies, Declarative Pipeline encourages a The docs spell out the correct syntax for a when { environment { ... } } block, which is: That said, perhaps you can do this more elegantly by using a matrix block? Set it up for a Pipeline script like the previous one, but set the Script Path to the Jenkinsfile in the script subdirectory. California law will base electricity bills on income levels, Essential reporting from around the world, Some experts are questioning Mountain Valley Pipeline's emissions estimates. Only run the steps in post if the current Pipeline’s exception handling support. a multibranch Pipeline.
