We are using delivery pipeline views, and we moved many of our build jobs to "Cloud" nodes ( ecs instances ) for which the workspace is not persisted after the build is finished.

As a result, token macro expansion is working fine during the build ( because the workspace exists ), but once the build is finished our pipeline displays un-expanded variables such as ${GIT_BRANCH} etc.

The cause is that the Token Macro plugin requires a workspace for calls to TokenUtil.expandAll() since version 2.0 .

Note that #JENKINS-40763 did a workaround for the issue: it just catches the exception raised by TokenUtils and displays the variables without expansion ( which is arguably much better than not showing a pipeline at all ).

As a workaround I did a fork which:

 - updates the dependencies to TokenUtils 2.0  ( required for access to new expandAll methods )

 - checks if the build has a valid workspace

 - if not, create a null "VirtualChannel" FilePath and changes the call to ExpandAll

Maybe there is a better solution. I am not a java developper but the fix might be useful to others.
