To do so, you'll need to define variables in the second stage at the job level, and then pass the variables as env: inputs. To define or modify a variable from a script, use the task.setvariable logging command. There are four different types of output variables with distinct syntaxes: When you use an output variable in the same job, you don't have to use the isoutput property. To set a variable at queue time, add a new variable within your pipeline and select the override option.

When you set a variable in the YAML file, don't define it in the web editor as settable at queue time. In this YAML, $[ dependencies.A.outputs['setvarStep.myOutputVar'] ] is assigned to the variable $(myVarFromJobA).

This new feature which has been released recently (Spring 2020) is very helpful and will allow pipeline stages to communicate better and efficiently. Macro syntax variables ($(var)) get processed during runtime before a task runs. The pipeline then contains a task that converts that output into a pipeline variable: In the next stage, we can grab that variable and use that as input by declaring it as a variable on the stage: The last task in the pipeline can then use that in the role assignments: Heres the complete pipeline. However, don't use a runtime expression if you don't want your empty variable to print (example: $[variables.var]).
