jenkins-debian-glue 0.18.4 / usr / bin / lintian-junit-report

#!/usr/bin/env ruby
# Purpose: run Debian package checks using lintian and report in JUnit format
################################################################################
# Notes:
# * for JUnit spec details see http://windyroad.org/dl/Open%20Source/JUnit.xsd
#
# Ideas:
# * integrate within Jenkins plugin (using jruby)
# * integrate in Violations plugin (for further reporting options)
