Maven build with liferay

Nice tutorial by http://www.eusia.info

Have a look !!!


Assuming that you have JDK and Maven set up in you machine, I will write here how we can have a liferay project in minimal effort and make it distributable in all environments.

We will use Maven archtype plug-in to create liferay project.

Consider a folder as your project home, like: /home/manna/examples/liferay

if you working with maven you can have several maven settings based on project requirements, so better to have a different maven settings file like here we have : /home/manna/.m2/eusiaweb.xml

<settings>
    <profiles>
        <profile>
            <id>examples</id>
            <repositories>
                <repository>
                    <id>sonatype</id>
                    <url>http://oss.sonatype.org</url>
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                </repository>
                <repository>
                    <id>maven</id>
                    <url>http://repo2.maven.org/maven2</url>
                    <snapshots>
                        <enabled>false</enabled>
                    </snapshots>
                </repository>
            </repositories>
        </profile>
    </profiles>
    <activeProfiles>
        <activeProfile>examples</activeProfile>
    </activeProfiles>
</settings>
