Other comments

The unit tests are very basic, just started to make the mechanics work, need to be more robust like automated checking instead of unlike whats done manually now. Will try to update them in next iterations. The reporting plugins are in place to enablke the plugin documentation in future for all the maven plugins defined

How to integrate with liferay maven projects

1. Create a liferay maven portlet project
2. Create a search-containers.xml file, an example is available in the liferay-maven-plugin/src/test_ folder
3. Run the maven command mvn liferay:build-search-container
4. A set of Java classes wil be generated in the src folder and set of jsps will be generated in the src/main/webapp folder
