[ERROR]
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

I have added the plugin in pom.xml

          <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <url>http://{my-ip}:{my-port}/manager/html</url>
                    <server>{server-name}</server>
                    <path>/{context-path}</path>
                </configuration>
            </plugin>

and corresponding server setting in $MAVEN_HOME/conf/settings.xml

    <server>
      <id>{server-name}</id>
      <username>{username}</username>
      <password>{password}</password>
    </server>

I am having Ubuntu instance at AWS with tomcat installed at root.
