Wrong version of pep8

Hi infra, I have seen this failure today: Triggered by Gerrit: http://gerrit.ovirt.org/28611 Building remotely on dcaro-ovirt-vm03-centos65 (db_slave centos6 os1) in workspace /home/jenkins/workspace/vdsm_master_pep8_gerrit ... + pep8 --version 0.5.1dev + git diff HEAD~ + pep8 --diff '--filename=*.py,*.py.in,*/vdsm,*/supervdsmServer' + sed 's%^./*%%' Usage: pep8 [options] input ... pep8: error: no such option: --diff + [[ 2 -ne 0 ]] + echo 'PEP8 Failed' PEP8 Failed + cat /home/jenkins/workspace/vdsm_master_pep8_gerrit/violations.xml Build step 'Groovy Postbuild' changed build result to UNSTABLE Finished: UNSTABLE Can someone explain why we see these errors again and again? Don't we have some automated way to install a slave with all needed tools? Maybe we need a vdsm-devel package depending on all the tools to make the CI/new developers life easier? Nir
