difference between echo and println in Jenkinsfile

Question

While writing pipelines in Jenkins using Groovy, we can interchangeably use echo and println statements. Is there any difference between these statements?

For example,

buildNumber = "1.10";
echo "BUILD #${buildNumber}";
println "BUILD #${buildNumber}";

Answer 1

There may be a slight difference, as echo is a step where println is groovy. The echo step may actually make a step reference on the output view of Jenkins step view and blue ocean steps. The println may just output a log without creating those extra visual step references in the UI.
