It would be useful to be able to include a Jenkins environment variable in the url entered.

The reason for this is that we use this url to link to a html report that contains further information. This report is part of the archive output of the build so we would like to be able to reference each report using the %BUILD_NUMBER% in the url.

Full list of variables that could be specified at https://wiki.jenkins-ci.org/display/JENKINS/Building+a+software+project#Buildingasoftwareproject-JenkinsSetEnvironmentVariables
