Bamboo plugin guide

Please keep in mind that customisations are beyond the scope of what's covered by Atlassian Support.

Bamboo Plugins Overview

A Bamboo plugin is a single JAR containing code, a plugin descriptor (XML) and usually some Freemarker template files to render HTML.

The plugin descriptor is the only mandatory part of the plugin. It must be called atlassian-plugin.xml and be located in the root of your JAR file.

Each plugin consists of one or more plugin modules. These are of different types (for example a report, or a post-build action) and each has an individual XML element describing it. Each module is described below together with the XML element required for it.

Here is a sample of the descriptor with highlighted elements:

1
2
<!-- the plugin key must be unique, think of it as the 'package' of the plugin -->
<atlassian-plugin key="com.atlassian.plugin.sample" name="Sample Plugin" plugins-version="2">
    <!-- a short block describing the plugin itself -->
    <plugin-info>
        <description>This is a brief textual description of the plugin</description>
        <!-- the version of the plugin -->
        <version>1.1</version>
        <!-- details of the plugin vendor -->
        <vendor name="Atlassian Software Systems Pty Ltd" url="https://www.atlassian.com"/>
    </plugin-info>

    . . . 1 or more plugin modules . . .
</atlassian-plugin>

Each plugin has a plugin key which is unique among all plugins (eg "com.atlassian.plugin.sample"). Semantically this equates to the package of a Java class. Each module within the plugin also has a module key which is unique within the plugin (eg "myreport"). Semantically this equates to the class name of a Java class.

The plugin key + module key are combined to make the complete key of the plugin module (combining the examples above, the complete key would be "com.atlassian.plugin.sample:myreport"). Note: a ":" is used to separate the plugin key from the module key.

Setting up a Bamboo Plugin Project

Refer to the Getting started with Atlassian plugins guide for information on how to set up a Bamboo plugin using the Atlassian Plugin Archetypes. You will require Maven 3 and Oracle JDK 21 or Adoptium JDK 21.

If you have a Commercial License you can obtain the Bamboo Source code by contacting support team.

Testing your Bamboo plugin.

Follow instructions at Create a HelloWorld plugin project page how to use atlas commands

1
2
atlas-run or atlas-debug

will compile your plugin's classes, create a jar in the /target directory, download a copy of the Bamboo war, copy the plugin jar into Bamboo's WEB-INF/lib directory and start up Bamboo. Maven will also install some default data such as the license and database configuration.

Bamboo will be running at http://localhost:6990/bamboo, so you can go directly there in your browser and see your latest changes. You'll be able to log in with the username admin and the password admin.

As you make changes, you'll have to kill the Bamboo process (ctrl-c) and then run atlas-debug again.

When you run Bamboo with the atlas-debug command, it is automatically configured to accept a remote debugger. So you'll want to create a remote debug target in your IDE for your plugin and/or the bamboo source.

Deploy a Bamboo Plugin

Installing plugins in Bamboo is easy.

Once you have downloaded or created your plugin jar, follow these steps:

For Bamboo instance with UPM 6.5.2+ add system property -Dupm.plugin.upload.enabled=true and restart Bamboo (this is required to allow uploading plugins via the UI)
Open UPM UI at http://BAMBOO_URL/plugins/servlet/upm
Upload jar file with your plugin using the "Upload app" button
Enjoy!

Built-in Bamboo system plugins

A number of functions and areas within Bamboo are shipped as built in plugins. These can also be useful for plugin developers who want to know more about how to create their own plugins, as they showcase the functionality that can be built.

The system plugins are referenced from the following files (located in /WEB-INF/classes:

system-actions-plugin.xml - the built-in per-plan build expiry configuration
system-builderConfiguration-plugin.xml -
system-dockerHadler-plugin.xml - the built-in Docker wrapper integration.
system-jira-plugin.xml - the built-in JIRA issue integration.
system-listeners-plugin.xml - the built-in event listeners for the Bamboo System.
system-notifications-plugin.xml - the built-in notification conditions, including all builds, failed builds, after X failed builds.
system-quick-filters-plugin.xml - the built-in Quick Filters rule types.
system-reports-plugin.xml - the built-in reports of builds grouped by time periods under the Reports tab.
system-repository-plugin.xml - definition for the SVN repository shipped with Bamboo.
system-servlets-plugin.xml - the built-in servlets and filters definitions.
system-shared-credentials-plugin.xml - the built-in shared credentials definitions.
system-triggerReason-plugin.xml - definition of all the built-in build trigger reasons such as manual build, dependency build and Scheduled build.
system-webUI-plugin.xml - the built-in menu items under the Administration tab as well as the tab menu items on the View Plan page and the View Build Results page.
