How to suppress source script lines echo in jenkins pipeline console output?
<p>I am writing a pipeline job in Jenkins which shows the output console of a downstream job in the pipeline console output. The job is working so far but the output is really hard to read due to all the echo lines added to the output by the pipeline job itself.</p>

<p>Is there an option, configuration, command or anything in the pipeline plugin or in Groovy or in Jenkins to allow me suppress all the extra "echoing" to make the console output more readable?</p>
