Bundled Development Package

TeamCity comes bundled with a Development Package that can be used to start developing TeamCity plugins.

To get the package, use the .tar.gz or .exe. distribution. Upon installation, <TeamCity Home Directory> will have the devPackage directory which contains TeamCity open API binaries, javadoc, sources and archive with a sample plugin.

devPackage directory description

There are mainly two types of plugins in TeamCity: server-side plugins and agent-side plugins. To develop an agent-side plugin, you need the following part of the Open API:

serviceMessages.jar
common-api.jar
agent-api.jar

Correspondingly for the server-side plugin, you need:

serviceMessages.jar
common-api.jar
server-api.jar

Note that sometimes a part of an agent-side plugin has to work in the same JVM where the build tool is executing. For example, some custom test runner can be executed in the JVM where the tests are running. The runtime directory of devPackage contains some jars that can be used in this case.

devPackage also contains some base classes for tests under the tests directory.

Sample Plugin

Building and deploying sample plugin

Building plugin with Apache Ant

Unpack <TeamCity Home Directory>\devPackage\samplePlugin-src.zip into a directory of your choice.
Edit the build.properties file and set the value for path.variable.teamcitydistribution property to the path of <TeamCity Home Directory>.
Run ant dist in the plugin directory (Ant 1.7\+ is recommended). The plugin distribution should be created in the dist directory.

Building sample plugin in IntelliJ IDEA

Unpack <TeamCity Home Directory>\devPackage\samplePlugin-src.zip into a directory of your choice.
Open the project in IDEA (the .idea project should work OK in IntelliJ IDEA 9 and later (including IntelliJ IDEA 9.0 Community Edition)).
On prompt to add the path variable, set the "TeamCityDistribution" path variable to the directory where TeamCity with devPackage is installed (<TeamCity Home Directory>).
Open Project Structure and ensure you have Project SDK with name "1.6" pointing to JDK version 1.6.

Running the server with plugin from IDEA

Edit the build.properties file to set the path.variable.teamcitydistribution property or regenerate the build script from IDEA (execute "Generate Ant Build" with the settings: single file, all other options unchecked).

If you use the Ultimate edition of IntelliJ IDEA, you can start TeamCity's Tomcat right form the IDE:

Go to the "server" run configuration settings and configure Application Server pointing it to <TeamCity Home Directory>.
Run the "server" run configuration. It will run Ant create distribution task, deploy the plugin into ${user.home}/.BuildServer directory and run the TeamCity server.

If you use the Community edition, see Building plugin with Apache Ant — you can run "deploy" Ant build target right from the Ant Build IDEA tool window and then start TeamCity manually.

Sample Plugin Functionality

The sample plugin adds "Click me!" button in the bottom of "Projects" page. Click it to navigate to the plugin description page.
