 You also can define your Pipeline directly in the project configuration window. If you select **Pipeline script** from the **Definition** drop-down menu, you can author your Pipeline code in the **Script** box. When you define your Pipeline this way, your Pipeline must include an additional stage to check out MATLAB code from source control.

 To update the system PATH environment variable using Declarative Pipeline syntax, use an `environment` block in your `Jenkinsfile`. For example, prepend MATLAB R2019a to the system PATH environment variable and use it to run your command.
