Answer 1

Add the repository location at you target file (smarthome.target). It will look something like this with different version maybe :

<repository location="http://download.eclipse.org/tools/orbit/downloads/drops/R20140525021250/repository/"/>
    <location includeAllPlatforms="false" includeConfigurePhase="true" includeMode="planner" includeSource="true" type="InstallableUnit">
      <unit id="org.codehaus.groovy23.feature.feature.group" version="0.0.0"/>
      <repository location="http://dist.springsource.org/release/GRECLIPSE/e4.4/"/>
    </location>
