Help Me Out !....................


  • Options

    As the error states, your failure threshold is set to WARN (which I think is the default unless you override it with --failure-threshold). 


    You can either fix the warnings that have been rasied, which is the ideal solution and the only one supported for production, or alternatively you can set --failure-threshold to something higher, FAIL, NONE etc.
