Reading file from Workspace in Jenkins with Groovy script

Question

I want to add a Build step with the Groovy plugin to read a file and trigger a build fail depending on the content of the file.

How can I inject the workspace file p

Answer 1

Based on your comments, you would be better off with Text-finder plugin.

It allows to search file(s), as well as console, for a regular expression and then set the build either unstable or failed if found.

As for the Groovy, you can use the following to access ${WORKSPACE} environment variable:
def workspace = manager.build.getEnvVars()["WORKSPACE"]
