You can use variables and regular expressions to create conditions that have to be met to run a task. This way you can skip build steps in plan branches, decide what tasks are mandatory and what could be skipped, etc. You can set conditions for tasks through Bamboo UI or by using Bamboo Specs. For more information, see Configuring Tasks.

The variable name shouldn't begin with bamboo. E.g., the variable bamboo.planRepository.branchName should be added as planRepository.branchName.

There aren't any notifications as to if the conditional task was either run or not. However, it's possible to check that in the build logs, like the examples below.

Example 1: a script task was skipped because it was configured with a condition that was not met.

simple 05-Aug-2021 19:08:18 Skipping task 'test script' because of unfulfilled condition. Reason: Variable abc equals 1

Example 2: a script task was executed because the condition was met.

simple	05-Aug-2021 19:09:01	All conditions for task 'test script' were met. Conditions: Variable abc equals 1
simple	05-Aug-2021 19:09:01	Starting task 'test script' of type 'com.atlassian.bamboo.plugins.scripttask:task.builder.script'
