Answer 1

Whatever plugin you have developed( portlets, themes, layout templates, hooks or Ext) you need to navigate to that specific plugin and then fire your command to deploy your plugin.
mvn clean package liferay:depoy
It is mentioned in your error that maven is not able to find the plugin as your path mentioned is wroong.

Answer 2

Try to include repositories to be downloaded by including this stuff on your pom:
<profiles>
<profile>
<id>Liferay-v6.2-CE-(Tomcat-7)</id>
<properties>
<liferay.version>Your_Liferay-Version</liferay.version>
<liferay.maven.plugin.version>6.2.5</liferay.maven.plugin.version>
<liferay.auto.deploy.dir>/opt/liferay-portal-6.2-ce-ga4/deploy</liferay.auto.deploy.dir>
<liferay.app.server.deploy.dir>/opt/liferay-portal-6.2-ce-ga4/tomcat-7.0.42/webapps</liferay.app.server.deploy.dir>
<liferay.app.server.lib.global.dir>/opt/liferay-portal-6.2-ce-ga4/tomcat-7.0.42/lib/ext</liferay.app.server.lib.global.dir>
<liferay.app.server.portal.dir>/opt/liferay-portal-6.2-ce-ga4/tomcat-7.0.42/webapps/ROOT</liferay.app.server.portal.dir>
</properties>
</profile>
</profiles>
