I have a working and deployable version of a plugin-based product file for my tool. Now I would like to switch to a feature-based product - in order to achieve a tycho build & root files.

My RCP application now comprises 4 features, one of those features contains the Xtext plugins (called MappingDsl here). The feature.xml looks like the following:

<?xml version="1.0" encoding="UTF-8"?>
<feature
      id="ch.hilbri.assist.features.mapping"
      label="Mapping"
      version="2.0.0.qualifier"
      os="linux,macosx,win32"
      ws="cocoa,gtk,win32"
      arch="x86_64">

   <license url="">
      GPL
   </license>

After adding 
org.eclipse.xtext.runtime
as a dependency, the validation fails and requires bundles like 
com.google.guava
and 
com.google.inject
. I cannot find these bundles in any of the features being presented for selection (when I hit "Add").

The plugin-based product works fine. Tycho-build with this feature-based product works fine. But validation fails and I am unable to start the PDE build, i.e. start the RCP application by clicking on the "Overview - Launch an Eclipse Application" link. Where can I get the missing dependency? Btw, those bundles are present in my target platform - I checked.

Hi Robert,

there is no feature containing these plugins, you need to add them to one of your own features.

Cheers,
Stefan

how does your target platform look like? you may have a look at https://github.com/eclipse/xtext/blob/master/releng/org.eclipse.xtext.releng/target-platforms/developer-mars.target does it work if you git add required in the launch config?
