Thanks for reply. I added it and I still get the same error message. Any more things  that I have missed that can cause these kind of errors?

Hi, first I recommend you specify the 
runtime environment, add in yout parent pom setting the plugin "target-platform-configuration"
pe. generate for windows x86
 <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>target-platform-configuration</artifactId>
        <version>${tycho.version}</version>
        <configuration>
          <filters>
            <!-- work around Equinox bug 348045 -->
            <filter>
              <type>p2-installable-unit</type>
              <id>org.eclipse.equinox.servletbridge.extensionbundle</id>
              <removeAll />
            </filter>
          </filters>
          <environments>
	      <environment>
		  <os>win32</os>
		  <ws>win32</ws>
		  <arch>x86</arch>
	     </environment>
           </environments>
