I am trying to create a Maven module that contains a Eclipse PDE project. I
therefore need the following imports:

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.handlers.HandlerUtil;
import org.eclipse.jface.dialogs.MessageDialog;

I have found jface:

<dependency>
<groupId>swt</groupId>
<artifactId>jface</artifactId>
<version>3.0m8</version>
</dependency>

from a site. But how do I get the other dependencies in Maven? I cannot find
them using the build in dependency manager.

Have a look at Tycho project [1], which provides set of Maven extensions
and plugins to build PDE projects with Maven. In particular, look at
sample application that shows P2-based target platform resolver.

Ok maybe I am missing the big picture here. In the PDE example an
application is created that uses the following imports:

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.handlers.HandlerUtil;
import org.eclipse.jface.dialogs.MessageDialog;

To do this the following dependencies are defined in the MANIFEST.MF file:

org.eclipse.ui (3.5.0)
org.eclipse.core.runtime (3.5.0)

So basically as I understand it should just be a matter of defining those
dependencies in the pom.xml file, end of story.

Why go to greater lengths than this?

You likely have mirrorOf=* or mirrirOf=external:* in your settings.xml.
Ublock repo with id=forge (defined in tycho global settings.xml) using
!forge in mirrorOf or remove the mirror completely.

In short, there is no universally correct mapping between Maven and
OSGi/Eclipse dependencies.

Transitive resolution works differently. OSGi import/export package and
classpath visibility rules have no analog in Maven at all. To name a
couple of differences. Besides, dependencies defined both in pom.xml and
manifest.mf will be quite laborious to keep in sync for lager projects.

Ok so first step is to make the TychoDemo work and then somehow use Thycho
to solve dependencies between the MANIFEST.MF file and the pom.xml file?

I would probably look at Tycho target platform management wiki [1] and
corresponding sample application [2].

[1]
https://docs.sonatype.org/display/M2ECLIPSE/Tycho+build+targ et+platform+management
[2] http://svn.sonatype.org/m2eclipse/tycho/trunk/tycho-demo/itp 01/
