Liferay with MAVEN : Deploying simple portlet

Introduction:-
OOTB Liferay IDE/SDK comes with ANT but Maven has some advantages over ANT. You may google more for the differences or a why?? to go for MAVEN.

Anyways, for Liferay we need to follow a bit out of the way procedure. Lets see, how it goes....

Pre-requisites:-


1. Download Liferay maven sdk zip (https://github.com/azzazzel/liferay-maven-sdk)
(1.1 Extract this
1.2 go to terminal/command prompt
1.3 liferay-maven-sdk> mvn install
1.4 liferay-maven-sdk> mvn archetype:generate)
2. Install maven on eclipse http://download.eclipse.org/technology/m2e/releases

Steps:-

1. Create a new Maven Project


2. Click Next


3. Select liferay-portlet-archetype for creating a portlet.


4. Set GroupId(your package), artifact Id(your portlet name), version(1.1) and package


5. Following is the project structure


6. Set values in demoMaven project pom.xml
<configuration>
                    <autoDeployDir>\home\priyanka\pfiles\bundles\deploy</autoDeployDir>
                    <appServerDeployDir>\home\priyanka\pfiles\bundles\tomcat-7.0.27\webapps</appServerDeployDir>
                    <appServerLibGlobalDir>\home\priyanka\pfiles\bundles\tomcat-7.0.27\lib\ext</appServerLibGlobalDir>
                    <appServerPortalDir>\home\priyanka\pfiles\bundles\tomcat-7.0.27\webapps\ROOT</appServerPortalDir>

                    <liferayVersion>6.1.1</liferayVersion>
                    <pluginType>portlet</pluginType>
                </configuration>

Change the values with your existing configuration of portal.(This is the path to your liferay-portal)

7. In your pom.xml replace
${liferay.version} with your liferay version, I am using 6.1.1 so I replaced with the same. So, finally pom.xml looks something like the following

<?xml version="1.0"?>

8. Go to your command prompt or Terminal(Linux)
Type:-
 mvn clean install liferay:deploy

Your first portlet is deployed with maven :)
