Parent Pom build problems with Liferay

I am trying to setup a small maven based project structure as follows Maven Structure ``` Project \pom.xml \Hello world portlet \pom.xml \Second Portlet \pom.xml ``` As you can see there are couple of portlet(in future theme,hook,etc under same structure) under Project. Now within individual portlets I am able to run liferay related maven tasks to deploy them individually by hitting mvn clean compile package liferay:deploy Now I am looking to build and deploy all the Liferay portlet related artifacts using the same command. In that case I am getting an error for the parent project itself(the child liferay modules are building fine). I am not sure why its trying to build the parent project too, though my intention is just run the liferay:deploy related tasks in child. Child POM Here's the pom.xml of child(This is by default generated when creating the portlet) ``` <?xml version="1.0"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test</groupId> <artifactId>helloworld</artifactId> <packaging>war</packaging> <name>hello-world-portlet Portlet</name> <version>1.0</version> <build> <plugins> <plugin> <groupId>com.liferay.maven.plugins</groupId> <artifactId>liferay-maven-plugin</artifactId> <version>${liferay.version}</version> <configuration> <autoDeployDir>${liferay.auto.deploy.dir}</autoDeployDir> <liferayVersion>${liferay.version}</liferayVersion> <apiDir>${service.api.dir}</apiDir> <warFileName>${war.file.name}</warFileName> <pluginType>portlet</pluginType> </configuration> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.3</version> <executions> <execution> <id>add-source</id> <phase>generate-sources</phase> <goals> <goal>add-source</goal> </goals> <configuration> <sources> <source>${service.api.dir}</source> </sources> </configuration> </execution> </executions> </plugin> <plugin> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>portal-service</artifactId> <version>${liferay.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>util-bridges</artifactId> <version>${liferay.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>util-taglib</artifactId> <version>${liferay.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>util-java</artifactId> <version>${liferay.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.portlet</groupId> <artifactId>portlet-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.4</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> </dependencies> <properties> <liferay.auto.deploy.dir>D:/Projects/Bosch/Liferay Developer Studio/liferay-portal-6.1.10-ee-ga1/deploy</liferay.auto.deploy.dir> <liferay.version>6.1.10</liferay.version> <liferay.maven.version>6.1.0</liferay.maven.version> <war.file.name>hellow-world-portlet.war</war.file.name> <service.api.dir>src/main/java-service-api</service.api.dir> </properties> </project> ``` Parent POM Here's the pom.xml of parent.

But it is trying to execute it for the parent as well. How can I avoid the third build to happen,which is of parent project.
