"Polling the Repository for changes" means that Bamboo will check out the source code on a regular basis and examine it for changes. If Bamboo detects a change, Bamboo triggers a build of your Plan.

To trigger a Plan's build by polling its source repository for changes:

  1. Navigate to the desired Plan, as described on Configuring a Plan.
  2. Click the 'Actions' dropdown and click 'Configure Plan'.
  3. Click the 'Repository' tab.
  4. In the 'Build Strategy' field, select 'Polling the Repository for changes' (see screenshot below).
  5. In the 'Polling Frequency' field, specify how often (in seconds) Bamboo should check out the source code and examine it for changes.
  6. Click the 'Save' button.
