Build

Use Maven 3.x to build the Liberty plug-ins and archetypes.

• mvn install : builds the plug-in and the archetypes.
• mvn install -Poffline-its -DwlpInstallDir=<liberty_install_directory> : builds the plug-in and the archetypes and runs the integration tests by providing an existing installation.
• mvn install -Ponline-its -DwlpVersion=<liberty_version> -DwlpLicense=<liberty_license_code> : builds the plug-in and archetypes and runs the integration tests by downloading a new server.
  • Liberty versions and their respective link to the license code can be found in the index.yml file. You can obtain the license code by reading the current license and looking for the D/N: line.

Information for release 2.0

A number of new features and changes were made in release 2.0 of the Liberty Maven plug-in and are described here.

Plug-ins

liberty-maven-plugin

liberty-maven-plugin provides a number of goals for managing a Liberty server and applications.

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>net.wasdev.wlp.maven.plugins</groupId>
                <artifactId>liberty-maven-plugin</artifactId>
                <version>2.0</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 plug-in 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

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 plug-in installs the Liberty runtime with the Java EE 7 Web Profile features from the Liberty repository.

Goals

The liberty-maven-plugin provides the following goals.

Goal	Description
install-server	Installs the Liberty runtime. This goal is implicitly invoked by all the other plug-in goals and usually does not need to be executed explicitly.
create-server	Create a Liberty server.
start-server	Start a Liberty server in background. The server instance will be automatically created if it does not exist.
test-start-server	Allows you to bypass automatically starting the server during the pre-integration-test phase with pom configuration or a Liberty-specific command line argument.
run-server	Start a Liberty server in foreground. The server instance will be automatically created if it does not exist.
stop-server	Stop a Liberty server. The server instance must exist and must be running.
test-stop-server	Allows you to bypass automatically stopping the server during the post-integration-test phase with pom configuration or a Liberty-specific command line argument.
package-server	Package a Liberty server.
clean-server	Deletes every file in the ${outputDirectory}/logs, ${outputDirectory}/workarea, ${userDirectory}/dropins or ${userDirectory}/apps.
dump-server	Dump diagnostic information from the server into an archive.
java-dump-server	Dump diagnostic information from the server JVM.
deploy	Deploy an application to a Liberty server. The server instance must exist and must be running.
undeploy	Undeploy an application to a Liberty server. The server instance must exist and must be running.
install-feature	Install a feature packaged as a Subsystem Archive (esa) to the Liberty runtime.
uninstall-feature	Uninstall a feature from the Liberty runtime.
install-apps	Copy applications specified as Maven compile dependencies to Liberty server's dropins or apps directory.
compile-jsp	Compile JSPs in the src/main/webapp into the target/classes directory

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.

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 installAppPackages is set to all or project and looseApplication is set to true.

The liberty-assembly default lifecycle includes:

Phase	Goal
pre-clean	liberty:stop-server
process-resources	maven-resources-plugin:resources
compile	maven-compiler-plugin:compile
process-test-resources	maven-resources-plugin:testResources
test-compile	maven-compiler-plugin:testCompile
test	maven-surefire-plugin:test
prepare-package	liberty:create-server, liberty:install-feature
package	liberty:install-apps, liberty:package-server
pre-integration-test	liberty:test-start-server
integration-test	maven-failsafe-plugin:integration-test
post-integration-test	liberty:test-stop-server
verify	maven-failsafe-plugin:verify
install	maven-install-plugin:install
deploy	maven-deploy-plugin:deploy

Example:

<project>
    ...
    <groupId>myGroup</groupId>
    <artifactId>myServer</artifactId>
    <!-- Create Liberty server assembly -->

Archetypes

liberty-plugin-archetype

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=net.wasdev.wlp.maven \
    -DarchetypeArtifactId=liberty-plugin-archetype \
    -DarchetypeVersion=2.0 \
    -DwlpPluginVersion=2.0 \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

liberty-archetype-webapp

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 liberty-maven-app-parent parent pom that binds liberty-maven-plugin goals to the Maven default build lifecycle.

Usage

mvn archetype:generate \
    -DarchetypeGroupId=net.wasdev.wlp.maven \
    -DarchetypeArtifactId=liberty-archetype-webapp \
    -DarchetypeVersion=2.0 \
    -DwlpPluginVersion=2.0 \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

liberty-archetype-ear

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=net.wasdev.wlp.maven \
    -DarchetypeArtifactId=liberty-archetype-ear \
    -DarchetypeVersion=2.1-SNAPSHOT \
    -DwlpPluginVersion=2.1-SNAPSHOT \
    -DgroupId=test \
    -DartifactId=test \
    -Dversion=1.0-SNAPSHOT

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>
