Hi,

I'm having problem where Jenkins is not able to generate the changes (e.g. "No changes from last build").  But changelog.xml exist and looks valid.  It looks like my issue is due to special characters (e.g. "&", and "+" at least) within the <clientId> tags such as below

<clientId>blahblah_&_blahblah</clientId>

I see the below in my Jenkins log:

Could not parse Perforce changelog: /var/lib/jenkins/jobs/<job name>/builds/28/changelog.xml
