1st build for a job always fails when trying to execute prescm build step:
05:45:36 Started by timer
05:45:36 Building on master in workspace /build/jenkins/jobs/BuildAllAndTest/workspace
05:45:36 Running Prebuild steps
05:45:36 [workspace] $ /bin/sh -xe /tmp/hudson3985561110537366831.sh
05:45:36 FATAL: command execution failed
05:45:36 java.io.IOException: Cannot run program "/bin/sh" (in directory
"/build/jenkins/jobs/BuildAllAndTest/workspace"): java.io.IOException: error=2,
No such file or directory
Fortunately there is another bug, failures in the prescm build step do not fail the build, so the job continues and creates the workspace, so the next build succeeds.
