This pipeline library contains a workaround for Jenkins issue JENKINS-27413. It provides a new step unstashParam that saves file parameter to a workspace.

See Jenkins User Handbook, chapter Extending with Shared Libraries on how to configure pipeline libraries.

In a pipeline script:

library "jenkinsci-unstashParam-library"
node {
   def file_in_workspace = unstashParam "file"
   sh "cat ${file_in_workspace}"
}

The above assumes the Jenkins job has a file build parameter named file.
