Problem

When attempting to add a Maven Executable Capability to Bamboo, there is no Maven option under Capability Type.

Bamboo Specs imports will also fail with an error similar to the below:

1 Don't know how to import task properties of type: com.atlassian.bamboo.specs.model.task.MavenTaskProperties

Cause

The Bamboo Maven plugin has likely been disabled or failed to initialise on the most recent Bamboo start-up due to a timeout (see Unable to compile soy template in plugin module for a similar issue with a different symptom)

Resolution

  1. Bamboo Administration >> Manage apps (or add-ons)

  2. Change the dropdown from User-installed to All apps (or add-ons)

  3. Type Maven into the Filter visible apps field.

  4. Expand Atlassian Bamboo Maven Tasks Plugin

  5. Click the Enable button
