Hi Mark, thanks for the response. Yes, the pod meets the requirements: - I haven't provided a jnlp container - cat is the command - tty is enabled - Additional default container: maven:3.5.4-jdk-8 (tried different ones)
What I've observed: - A build step with a sleep of 60 seconds always works - A build step with a sleep of 70 seconds always fails I was wondering, could be a 60 seconds timeout in either the JNLP or somewhere else?
