1> First of all execute the command : mvn archetype:generate
When execute this command the option comes to select which kind of the liferay plugin want to make. For example i want to make a service builder then the option withe in value liferay-service then while structure will be generated. In the option we have various option to make maven based hook,ext,portlets.
2> run the command : mvn eclipse:eclise
This will make the code into the project so we can directly import the code into the eclipse.
3> In the ant base portlet we have portlet structure as following.
bookmark-portlet
|_ docroot
|_css
|_js
|_jsp
|_meta-inf
|_web-inf
|_lib
|_src
|_liferay-display.xml
|_liferay-hook.xml
|_liferay-plugin-package.properties
|_liferay-portlet.xml
|_portlet.xml
|_web.xml
|_ build.xml
For the maven portlet we have following structure.
bookmark-portlet
|_src
|_main
|_java (our java code comes here)
|_ resource(our property files should come here)
|_web-apps
|_css
|_js
|_jsp
|_web-inf
|_liferay-display.xml
|_liferay-hook.xml
|_liferay-plugin-package.properties
|_liferay-portlet.xml
|_portlet.xml
|_web.xml
For migration from ant portlet to the maven portlet put the all the java classes in to the main.java class. Put al the propertiesis and file of the meta-inf into the resource.
for the service buildes two folders has been generated like
bookmark
|_bookmark-portlet(All the portlet related classes)
|_bookmark-service-portlet(All the classes generated by the service builder.)
|_pom.xml
4> After doing this run the command mvn clean install it will meke the war into the target folder of the respective portlet. Take a portlet put it into the deploy folder of the tomcat.
