Use Case:

Assume we have to define some variables that can defined at runtime which is further required to pass -->

Within Same Job Different Steps

Within Same Stage Different Jobs

Within Different Stage

Dependencies:

We can use the dependencies keyword for referring the previous stage and jobs

Keyword

1. dependencies

2. stagedependencies

Syntax

Same Stage

dependencies.<Job-name>.outputs['<step-name>.<variable-name>']

Different Stage

stageDependencies.<Stage-name>.<Job-name>.outputs['<step-name>.<variable-name>']

Same Job

<step-name>.<variable-name>
