Thanks to Esteban add-on on Smalltalkhub, it is now possible to notify Jenkins that there is a new package published for your project. What we do for now is to poll very often (each minute) smalltalkub to check if there is an update. It is a big waste of resources! Now we can do better! It would be very nice to update your jobs to now use the commit hook. Here is the way to go: go to your job configuration on Jenkins In the build triggers section, enable Trigger builds remotely (e.g., from scripts) and choose an authentication token. disable [URLTrigger] - Poll with a URL go to smalltalkhub, on your project settings page Fill in the commit hook url field with https://ci.inria.fr/pharo-contribution/buildByToken/build?job=JOBNAME&token=... by replacing JOBNAME and TOKEN by the Jenkins job name and the token chosen. In the end, the build is now triggered immediately after the commit (no more delay). Christophe
