After I "execute shell" a command that holds for key press the jenkins terminate it.
The command that I'm using is "atlas-mvn -B jira:run &" and I have started the jenkins with "java -Dhudson.util.ProcessTreeKiller.disable=true -jar hudson.war" and seted the envvar "BUILD_ID=dontKillMe"

The log that I get is that:
