fuse-7.5.sb2-release-pipeline broken on narayana-spring-boot

it has failed 2 times in a row: https://fusesource-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/fuse-7.5.sb2-release-pipeline/8/console

last time it has passed is on the 31 July https://fusesource-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/fuse-7.5.sb2-release-pipeline/5 (but maybe there was no modifications)

i don't see a specific error in log.

there is the generic one when the pipeline is failing:
