The Tycho plugins insert dependencies from MANIFEST.MF into the POM as system scope with the SNAPSHOT/qualifier resolved. Here is the effective-pom entry for a dependency on org.eclipse.ui plugin declared in MANIEFST.MF

    <dependency>
      <groupId>p2.eclipse-plugin</groupId>
      <artifactId>org.eclipse.ui</artifactId>
      <version>3.106.1.v20141002-1150</version>
      <scope>system</scope>
      <systemPath>/d01/sandboxes/hbl4218/m2/p2/osgi/bundle/org.eclipse.ui/3.106.1.v20141002-1150/org.eclipse.ui-3.106.1.v20141002-1150.jar</systemPath>
    </dependency>


It would be nice to be able to use the Trigger Dependencies feature for Maven+Tycho builds of Eclipse RCP projects.
