Build

Use Maven 3.5.0 or later to build the Liberty plugins and archetypes.

• mvn install : builds the plugin and the archetypes.
• mvn install -Poffline-its -DlibertyInstallDir=<liberty_install_directory> : builds the plugin and the archetypes and runs the integration tests by providing an existing installation.
• mvn install -Ponline-its -Druntime=<ol|wlp> -DruntimeVersion=<runtime_version> : builds the plugin and archetypes and runs the integration tests by downloading a new server. Set runtime to ol to run tests using the Open Liberty runtime, or wlp to run tests using the WebSphere Liberty Java EE 7 runtime.

Plugins

Liberty Maven Plugin

The Liberty Maven Plugin provides a number of goals for managing a Liberty server and applications. Maven 3.5.0 or later is recommended to use the Liberty Maven Plugin.

Release 3.0 differences

The new capabilities and behavior differences are summarized in the Liberty Maven Plug-in 3.0 release notes.

Configuration

To enable Liberty Maven Plugin in your project add the following to your pom.xml:

<project>
    ...
    <build>
        <plugins>
            <!-- Enable liberty-maven-plugin -->
            <plugin>
                <groupId>io.openliberty.tools</groupId>
                <artifactId>liberty-maven-plugin</artifactId>
                <version>[3.3.4,)</version>
                <!-- Specify configuration, executions for liberty-maven-plugin -->
                ...
            </plugin>
        </plugins>
    </build>
    ...
</project>

If you are using a snapshot version of Liberty Maven Plugin then you will also need to add the following plugin repository to your pom.xml:

<project>
    ...
    <pluginRepositories>
        <!-- Configure Sonatype OSS Maven snapshots repository -->
        <pluginRepository>
            <id>sonatype-nexus-snapshots</id>
            <name>Sonatype Nexus Snapshots</name>
            <url>https://oss.sonatype.org/content/repositories/snapshots/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
            <releases>
                <enabled>false</enabled>
            </releases>
        </pluginRepository>
    </pluginRepositories>
    ...
</project>

Liberty installation configuration

The Liberty Maven Plugin must first be configured with the Liberty server installation information. The installation information can be specified as an existing installation directory, a packaged server, or as a Maven artifact. The Liberty Maven Plugin can also download and install a Liberty server from the Liberty repository or other location using the install parameter. By default, the plugin installs the Open Liberty runtime from Maven Central.

Goals

The Liberty Maven Plugin provides the following goals.

Common Parameters

Parameters shared by all goals. See common parameters.

Common Server Parameters

Additional parameters shared by all server-based goals. See common server parameters.

Extensions

Extensions improve the compatibility or user experience of third party libraries used with Liberty. The Liberty Maven Plugin provides the following extensions.

Packaging types

liberty-assembly

The liberty-assembly Maven packaging type is used to create a packaged Liberty server Maven artifact out of existing server installation, compressed archive, or another server Maven artifact. Any applications specified as Maven compile dependencies will be automatically packaged with the assembled server. Liberty features can also be installed and packaged with the assembled server. Any application or test code included in the project is automatically compiled and tests run at appropriate unit or integration test phase. Application code is installed as a loose application WAR file if deployPackages is set to all or project and looseApplication is set to true.

The liberty-assembly default lifecycle includes:

Example:

<project>
    ...
    <groupId>myGroup</groupId>
    <artifactId>myServer</artifactId>
    <!-- Create Liberty server assembly -->
    <packaging>liberty-assembly</packaging>
    ...
    <dependencies>
        <!-- Package SimpleServlet.war with server assembly -->
        <dependency>
            <groupId>wasdev</groupId>
            <artifactId>SimpleServlet</artifactId>
            <version>1.0</version>
            <type>war</type>
        </dependency>
    </dependencies>
    ...
    <build>
        <plugins>
            <!-- Enable liberty-maven-plugin -->
            <plugin>
                <groupId>io.openliberty.tools</groupId>
                <artifactId>liberty-maven-plugin</artifactId>
                <version>[3.2.3,)</version>
                <extensions>true</extensions>
                <configuration>
                    <installDirectory>/opt/ibm/wlp</installDirectory>
                    <serverName>test</serverName>
                    <features>
                        <acceptLicense>true</acceptLicense>
                        <feature>mongodb-2.0</feature>
                    </features>
                    <looseApplication>true</looseApplication>
                    <deployPackages>all</deployPackages>
                </configuration>
            </plugin>
        </plugins>
    </build>
    ...
</project>

Archetypes

By default, all archetypes that specify a Liberty runtime use the latest version of the Open Liberty runtime. You can use a different runtime by setting the runtimeGroupId and runtimeArtifactId. For example, you can use wlp-webProfile7 by setting -DruntimeGroupId=com.ibm.websphere.appserver.runtime and -DruntimeArtifactId=wlp-webProfile7.

The runtime version can also be set dynamically. For example, you can specify version 20.0.0.3 of the runtime by setting -DruntimeVersion=20.0.0.3.

Finally, the default Liberty Maven Plugin version is set to be the latest version of the plugin. To specify a different version of the plugin, use the libertyPluginVersion parameter. For example, you could set -DlibertyPluginVersion=3.2.

liberty-plugin-archetype

The liberty-plugin-archetype is used to generate a basic multi-module project that builds a simple web application then deploys and tests it on a Liberty server. It also creates a Liberty server package that includes the application.

Usage

mvn archetype:generate \
    -DarchetypeGroupId=io.openliberty.tools \
    -DarchetypeArtifactId=liberty-plugin-archetype \
    -DarchetypeVersion=3.2.3  \
    -DlibertyPluginVersion=3.2.3  \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

liberty-archetype-webapp

The liberty-archetype-webapp is used to generate a basic single-module project that builds a simple web application then deploys and tests on a Liberty server. It also creates a minified, runnable Liberty server package that includes the application. The generated project includes the liberty-maven-app-parent parent pom that binds Liberty Maven Plugin goals to the Maven default build lifecycle.

Usage

mvn archetype:generate \
    -DarchetypeGroupId=io.openliberty.tools \
    -DarchetypeArtifactId=liberty-archetype-webapp \
    -DarchetypeVersion=3.2.3 \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

liberty-archetype-ear

The liberty-archetype-ear is used to generate a multi-module project that includes an EJB module, a web application module and an EAR module. In the EAR module, it packages the application in a Java EE 7 Enterprise Archive then deploys and tests on a Liberty server. It also creates a minified, runnable Liberty server package that includes the application EAR file. The generated project includes liberty-maven-app-parent parent pom that binds Liberty Maven Plugin goals to the Maven default build lifecycle.

Usage

mvn archetype:generate \
    -DarchetypeGroupId=io.openliberty.tools \
    -DarchetypeArtifactId=liberty-archetype-ear \
    -DarchetypeVersion=3.2.3  \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

Using Archetype Snapshots

If you are using a snapshot version of liberty-archetype-webapp or liberty-archetype-ear, then you will also need to add the following archetype repository to ${user.home}/.m2/settings.xml:

<settings>
    ...
    <profiles>
        <profile>
            <id>archetype-snapshot-repo</id>
            <properties>
                <archetypeRepository>https://oss.sonatype.org/content/repositories/snapshots
                </archetypeRepository>
            </properties>
            <repositories>
                <repository>
                    <id>sonatype-nexus-snapshots</id>
                    <name>Sonatype Nexus Snapshots</name>
