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

If you already have the Groovy (Postbuild) plugin installed, I think it's a valid desire to get this done with (generic) Groovy instead of installing a (specialized) plugin.

That said, you can get the workspace using manager.build.workspace.getRemote(). Don't forget to add File.separator between path and file name.
