You can configure Bamboo to poll the repository for source code changes, either:
- periodically (e.g. every 180 seconds), or
- based on a schedule (e.g. the second Sunday of every month at 5:00 am).
If Bamboo detects a change in the source code, a build of your plan is triggered.
To configure Bamboo to poll the repository for source code changes:
- Click Dashboard and then the All Plans tab.
- Locate the plan in the list and click the edit icon (
) to display the plan's configuration pages. - Click the Triggers tab, then click either an existing trigger or Add Trigger.
- Optionally, enter a trigger description.
- Choose Trigger type > Polling the Repository for changes.
- Bamboo displays the available repositories for the plan, as previously configured on the Source Repositories tab. Choose the repositories that this trigger should apply to.
Choose a polling strategy:
Periodically Enter a Polling Frequency value (in seconds) for the time between when Bamboo checks for repository changes. Scheduled Click the edit icon ( ) to use the Schedule Editor to set the polling schedule.
Note, this is a schedule for polling your repository: a plan build will only be triggered if there are source code changes. See Triggering builds.
