[Bamboo Knowledge Base]
Triggering in Bamboo allows plan builds to be started automatically. Bamboo has the following trigger methods:
Trigger a build if code has changed:
Trigger a build based on a schedule:
Trigger a build depending on the outcome of other plans:
Note that a plan that has no configured triggers can only be started manually, or if it is dependent on the successful build of another plan.
From Bamboo 4.3, you can configure multiple triggers for each plan. This allows a plan to be triggered by different trigger types, and to have triggering scenarios such as "every 5 minutes between 9:00am and 10:00am, and every 20 minutes between 1:00pm and 10:00pm".
Triggers can only be configured by a Bamboo administrator.
This table lists the ways in which plan builds can be triggered in Bamboo. Triggering option Description Polling the repository for changes Bamboo will 'poll' the selected source code repositories for code changes, using either a specified interval (that is, periodically) or a schedule. If Bamboo detects code changes, a build of the plan is triggered. Repository triggers the build when changes are committed Bamboo waits to receive a message about changed code from any of the selected source code repositories. When Bamboo receives such a message, a build of the plan is triggered. See Repository triggers the build when changes are committed. Cron-based scheduling Bamboo will trigger scheduled builds of this plan based on a cron expression. Single daily build Bamboo will trigger a build of the plan once per day at a specified time. See Single daily build.
This feature is only available when configuring an existing plan.
You can choose to run builds of this plan only if other specified plans are currently passing. Those plans must build successfully before this plan will be built. See also Setting up plan build dependencies.
Note that, because a plan may have multiple triggers configured, each of which can have differing trigger conditions, it is possible for the plan build to be started by one trigger, even though another trigger is currently blocked.
