keith is this on 1.3 or master?
Michael Neale it's on 1.3, from what I can tell
ok this is a pretty big deal. I can't remember if Bitbucket was in 1.2? if so - this is a dependency problem (BB is dragging in an incompatible http commons Vivek Pandey?)
Looks like this regression got introduced since dependency fix problem as part of PCT.
Vivek Pandey can you given an update to Keith about this if you solve it? (can be merged into 1.3 and master if you sort it out overnight).
Fixed on master and release/1.3.
The planned https://issues.jenkins-ci.org/browse/JENKINS-45393 should help prevent regressions like this in the future.
