I have encountered an issue during seed job verify.

Error: Invalid or corrupt jarfile /repo/bbijenkins/workspace/job-dsl-verify/fem004-eiffel002/build/job-dsl-core-1.57-standalone.jar
13:16:38 Build step 'Execute shell' marked build as failure

Also one more error during the same seed job verify

Both the errors occured at different time periods.

Done some googling but did not find the clue to fix this problem,
