Reference Guide

These are the various XML configuration elements that you can use to configure the Cargo Maven2 plugin. Make sure you also check the examples which show how to use them.

Top level configuration elements	Description	Default value
`<configuration>`	Definition of a Configuration	Defaults to a standalone configuration if the container is of type local and a runtime one if it's of type remote
`<container>`	Definition of a Container	Defaults to a Jetty 7.x installed container if not specified
`<deployer>`	Definition of a Deployer	Defaults to a deployer matching the container's type if none is specified (installed local deployer for an installed container, remote deployer for a remote container and embedded local deployer for an embedded container)
`<deployables>`	A list of deployables that are going to be deployed in the container when it is started or when `cargo:deploy` / `cargo:undeploy` is called.	If the project's packaging is `war`, `ear` or `ejb`, the generated artifact is added automatically to the list of deployables to deploy. If you wish the generated artifact not to be added to the deployables list, just add an empty `<deployer/>` element.
`<daemon>`	Additional configuration that is used when deploying with the Cargo Daemon.	For more information, please read: Cargo Daemon.
`<skip>`	Set this to `true` to bypass cargo execution	Defaults to `false`, you can also steer it using the system property `cargo.maven.skip`

`<configuration>` elements	Description	Default value
`<configfiles>`	List of Configuration files that are to be added to a local container's configuration. Each file is specified using a `<configfile>` element. Cargo token replacement is applied to the files and any existing file is overwritten.	No default
`<files>`	List of files that are to be added to a local container's configuration. Each file is specified using a `<file>` element.	No default
`<home>`	For standalone configuration this is the location where Cargo will create the configuration and for existing configuration this is where it is located	`${project.build.directory}/cargo/configurations/${containerId`}
`<implementation>`	Full classname of a custom configuration implementation to use. In that case the custom configuration is registered with the `<containerId>` and `<type>` specified	Defaults to the Cargo-provided implementation if not specified
`<properties>`	Values to use for various Configuration properties. You can also use the `<propertiesFile>` element to load configuration properties from a file.	Default configuration properties Note that these configuration properties can also be overriden using Java properties; for example: mvn -Dcargo.servlet.port=8082 cargo:start In addition to this, properties can also be set using the Maven2 `settings.xml` file. See the setting configuration options via the Maven settings.xml section for details.

`<timeout>`	The timeout after which Cargo reports an error if the container is not started or stopped	`120000` ms (2 minutes)
`<type>`	The container's type. Valid values are `installed`, `embedded` and `remote`	Default value is `installed` unless the `<containerId>` has not been specified, in which case the default is to use the Jetty 7.x installed container
`<zipUrlInstaller>`	Defines the location of a container distribution zip that will be downloaded and installed	No default If the user has not defined any `home`, `<zipUrlInstaller>` nor `<artifactInstaller>` element then the plugin will automatically attempt to download the container using the URL used by its tests (see the Tested On section of each container).

`<pingURL>`	URL on which to ping the deployed or undeployed application (to check if deployment or undeployment is successful), that should return an HTTP OK response only after the deployment is complete. If not set, the deployed or undeployed application will not be pinged, hence the deployment considered as complete as soon as the target server's method returns successfully.	No default
<pingUrlPath>	URL path used to ping the deployed or undeployed application.

About WAR contexts

Many containers have their specific files for redefining context roots (Tomcat has context.xml, JBoss has jboss-web.xml, etc.). If your WAR has such a file, the server will most probably use the context root defined in that file instead of the one you specify using the CARGO deployer.

`<dependency>` elements	Description	Default value
`<artifactId>`	Maven's artifact id. This artifact id must match a specified `<project>/<dependencies>/<dependency>` artifact id	Defaults to the project's artifact id

`<type>`	Maven's type. This type must match a specified `<project>/<dependencies>/<dependency>` type	Defaults to the project's packaging
`<classpath>`	Target classpath, either `extra` (default) or `shared`. Shared application classpath deployment is only available for local containers which support shared Application Classpaths.	`extra` (container classpath)
`<location>`	The path of a folder or a jar file you wish to add to deployable classpath. This element can be used to explicitly add entries to the classpath. For example: <dependency> <location>src/main/resources/conf</location> </dependency>	If the groupId and artifactId match those of the project then the deployable is the artifact generated by the project. Otherwise the location is the location of the dependency in your local respository.

`<proxy>`	Proxy server settings, if required.	No default

Automatic proxy settings

Note that CARGO will by default reuse existing Maven2 proxy configuration -so you won't need to type the proxy settings for the zipUrlInstaller element.

`<proxy>` elements (under the `zipUrlInstaller` element)	Description	Default value
`<cargo.proxy.host>`	Proxy host name or IP address.	No default
`<cargo.proxy.port>`	Proxy port.	Very probably `80`

Daemon configuration

The Cargo Daemon is a Web-based application that uses the Cargo API to configure, start and stop containers on a remote machine. The daemon is meant to be listening 24/7, to allow users to deploy new containers and web applications at their command. For more information, please read: Cargo Daemon.

Container configuration for the Daemon

For the Maven2/Maven3 plugin, the "daemonized server" is actually a local container with a hostname that points to a remote machine. This implies that:

You should not set the container type to a remote container nor add any remote deployers to the configuration; but instead define the container as a local container (with either a standalone or existing configuration)
When you define the home paths for the container and the configuration, remember these paths are for the machine where the Daemon is running (and, preferably, use absolute paths)

When you call cargo:daemon-start, the Maven2/Maven3 plugin will do the following:

If an installer is defined:
- Download the archive locally
- Send the archive over to the machine running the Daemon
- Instruct the Daemon to extract the archive
If a standalone local configuration is defined, instruct the Daemon to create it
In all cases:
- Send the configuration files and deployables to the machine running the Daemon
- Instruct the Daemon to deploy them
Finally, instruct the Daemon to start the container

`<daemon>` elements	Description	Mandatory?	Default value
`<classpaths>`	A list of `<classpath>myclasspath</classpath>` items, that will be added by the JVM launcher when starting a container.		No default
`<properties>`	A list of properties used to configure the Cargo Daemon.		No default

`<properties>` elements	Description	Default value
`<cargo.daemon.url>`	URL to connect with the daemon.	No default
`<cargo.daemon.handleid>`	The handle id to register this container with.	No default
`<cargo.daemon.autostart>`	When set to `true`, the dameon will automatically restart the container if the daemon notices it is stopped.	`false`
`<cargo.daemon.username>`	Username used when authenticating against the daemon host	`admin`
`<cargo.daemon.password>`	Password used when authenticating against the daemon host	`""` (empty String)

Setting configuration options via the Maven settings.xml

The Cargo Maven2/Maven3 plugin also allows you to define container configuration properties using the settings.xml file. This way, you can for example store properties like usernames and passwords in a centralized location (as opposed to pom.xml files).

First, add the configuration properties you would like in your settings.xml file's <servers> section:

<servers>
  <server>
    <id>jonas1</id>
    <configuration>
      <cargo.remote.uri>jmx://jonas1</cargo.remote.uri>
      <cargo.jonas.domain.name>jonas</cargo.jonas.domain.name>
      <cargo.remote.username>jonas</cargo.remote.username>
      <cargo.remote.password>jonas</cargo.remote.password>
    </configuration>
  </server>
<servers>

Then, in the Cargo plugin's configuration, use the cargo.server.settings property in order to reference the configuration properties that you have previously defined. For example:

<plugin>
  <groupId>org.codehaus.cargo</groupId>
  <artifactId>cargo-maven2-plugin</artifactId>
  <configuration>
    [...]
    <configuration>
      <properties>
        <cargo.server.settings>jonas1</cargo.server.settings>
      </properties>
    </configuration>
  </configuration>
</plugin>

In this case, the plugin will internally "expand" the configuration into:

<plugin>
  <groupId>org.codehaus.cargo</groupId>
  <artifactId>cargo-maven2-plugin</artifactId>
  <configuration>
    [...]
    <configuration>
      <properties>
        <cargo.remote.uri>jmx://jonas1</cargo.remote.uri>
        <cargo.jonas.domain.name>jonas</cargo.jonas.domain.name>
        <cargo.remote.username>jonas</cargo.remote.username>
        <cargo.remote.password>jonas</cargo.remote.password>
      </properties>
    </configuration>
  </configuration>
</plugin>

Careful with properties set in the POM

Priority for property values are as follows:

Highest priority: Properties set using environment variables
Second priority: Properties that should be loaded using the cargo.server.settings option
Third priority: Properties loaded from a file
Lowest priority: Properties set in the POM
