set unstable
catchError( message: 'script failed', buildResult: 'UNSTABLE', stageResult: 'UNSTABLE' ) { sh( 'false' ) }
Signals an error. Useful if you want to conditionally abort some part of your program. You can also just
throw new Exception()
, but this step will avoid printing a stack trace
error( 'failed the build' )
Prints a message to the log and sets the overall build result and the stage result to UNSTABLE. The message will also be associated with the stage result and may be shown in visualizations.
