Example of using weblogic-maven-plugin

Using weblogic-maven-plugin

Author: Steve Button

Date: Jan/Feb 2015

This project contains a simple Maven project that configures and uses the weblogic-maven-plugin to deploy an application to a running WebLogic Server instance.

The coordinates of the plugin you want to be using are:

<groupId>com.oracle.weblogic</groupId>
<artifactId>weblogic-maven-plugin</artifactId>
<version>12.1.3-0-0</version>

The weblogic-maven-plugin:12.1.3-0-0 can perform most of its operations without needing any trace of a local WebLogic Server installation. It obtains its necessary libraries as ... maven artefacts.

The maven artefacts can be retrieved from a local/corp repository that has been populated using the oracle-maven-sync:12.1.3-0-0 plugin. This plugin will populate a specified repository with the artefacts that are present in a WebLogic Server installation, including the plugin itself.

As of January 2015 the plugin and artefacts can also be retrieved from the Oracle Maven Repository - see http://maven.oracle.com

Configuring weblogic-maven-plugin

The canonical pom.xml to use the weblogic-maven-plugin is this:

    </plugins>
  </build>
</project>

Command Line Invocation

Note: all these goals shown below (and more) do not require a local installation of WebLogic Server to execute - no middleWare home settings is needed.

To execute the goals successfully a server has to be running somewhere to use as a target for the operation :-)

To perform a deploy operation

$ mvn com.oracle.weblogic:weblogic-maven-plugin:deploy

To perform a redeploy operation

$ mvn com.oracle.weblogic:weblogic-maven-plugin:redeploy

To perform an undeploy operation

$ mvn com.oracle.weblogic:weblogic-maven-plugin:undeploy

To see the list of deployed applications

$ mvn com.oracle.weblogic:weblogic-maven-plugin:undeploy

Execution Phase Binding for Automatic Invocation

The relevant goals of the weblogic-maven-plugin can be bound to the maven phases so they are automatically executed as part of the maven lifecycle.

<plugin>
  <groupId>com.oracle.weblogic</groupId> 
  <artifactId>weblogic-maven-plugin</artifactId> 
  <version>12.1.3-0-0</version> 
  <configuration> 
    <user>weblogic</user>
    <password>welcome1</password>
    <name>${project.build.finalName}</name>
    <source>${project.build.directory}/${project.build.finalName}.${project.packaging}</source>          
  </configuration> 
  <!-- ## Can also bind goals to execution phases for automatic execution ## -->
  <executions>
    <execution>
      <id>up</id>
      <phase>pre-integration-test</phase> 
      <goals> 
        <goal>deploy</goal> 
      </goals>
    </execution> 
    <execution>
      <id>down</id>
      <phase>post-integration-test</phase> 
      <goals> 
        <goal>undeploy</goal> 
      </goals>
    </execution> 
  </executions>
</plugin>

When the maven verify command is issued, the deploy and undeploy goals will be executed using the common configuration values in the respective pre and post integration-test phases.

$ mvn verify
