Build a Liferay portlet war via Maven

Most posts on the internet regarding "How to build a war file of Liferay portlet" topic, cover only Ant tool. I find Maven as a next-gen project build tool and in this post I'll show how to use it to build Liferay portlet war.

There are 2 options to build portlet war: via command line or via eclipse liferay plugin.

To build portlet war via command line:

  1. Add new maven profile (maven settings.xml):
  2. Build usual war file using this command in project dir: mvn clean install
  3. Generated war needs to be modified according to the liferay portlet specification: mvn liferay:direct-deploy -DunpackWar=false -DappServerType=tomcat -DpluginType=portlet -P life

at this step war will be modified and placed to c:\liferay\Tomcat\webapps.

liferay:direct-deploy plugin makes some changes to war: adds information to web.xml, adds liferay files, etc.


To build portlet war via eclipse liferay plugin:

  1. Install liferay eclipse plugin.
  2. Project settings -> MAVEN -> Active Maven Profiles, set profile name that was specified for current project (for example "life", see upper part of this document).
  3. Invoke project's maven liferay:direct-deploy command that will copy unpacked war content to deploy.dir. War in this case not generated.
