Re: [p2-dev] Is it possible to install a feature into an RCP app at build time?

You can simplify these for Tycho and just specify the id attribute; that'll cause Tycho to pick up the latest version.  I doubt Tycho even uses the url attribute.

Tycho will find it as long as the feature is available in either your ~/.m2/repository, one of the configured <repository/>, or is one of the projects being built.

Ah, that's likely the problem: the repository has to be added to your list.  You should be able to add something like the following to your pom.xml:

  <repositories>
    <repository>
      <id>jre</id>
      <layout>p2</layout>
      <url>http://mydomain.com/p2reposiotry/myotherfeature/</url>
    </repository>
  </repositories>

(note that there appears to be a typo: "reposiotory" vs "repository")

Well I do it in my product builds and have been for over a year ;)
