properties(pipelineTriggers([pollSCM('H/5 * * * *')])])

checkout() command using GitSCM

The branch configurations are created correctly (the triggers are registered). SCM poll log updates every 5 minutes, but shows "No changes" despite there being changes on the remote branch. When building, changes are picked up for Jenkins changelog and the "Last Built Revision" is correct - everything works ok, except that polling does not register changes and therefor not trigger.

I know I should use a commit hook, but for now this is not possible.
