Cognitive Interaction Toolkit

Using environment variables within a freestyle project in the shell.command produces an empty shell.command and does not throw any errors.

The generator itself never interacts with environment variables. Variable references of the form ${NAME..} or @{NAME..} are expanded against variables defined and inherited in recipes.

To access environment variables in the generated shell fragments, escape the variable substitutions like this \\${NAME..}.

Not producing any output when encountering references to undefined variables is by design (but may have been a bad design decision).
