Hello,

Build timeout plugin supply two kind of timeout steps:

Build environment => "Abort if the build is stuck" 

If the job it is configured with this step, the TimeoutChecker flag gets correctly green 

Build Step => "Run with timeout"

If the job it is configured with this step, the TimeoutChecker flag gets red: also this step should be detected as a correctly configured job.

Best Regards,

Roberto

P.S. is there in generale more detailed documentation on jenkinslint plugin, with some example on how to fix the jobs?
