Thank you all. Sorry for answering so late. I was on holidays leave.
@thor the project de.bund.bfr.knime.fsklab.feature is not a plugin but a feature project like in the example from the tutorial, my.example.update. In this example project there are also two configuration files: bm.properties and buckminster.json. Maybe there are needed in my project?
@Vernalis thanks for your suggestion! I have seen it in other Buckminster configurations but my idea was to use the mutable property of the provider. If I am not wrong, this only pulls the changes and not the whole repository on each build.
@sonnenburg currently I a looking into Tycho but so far I have not been able to debug the Tycho build with a target as an RCP application. Following the Vogella tutorial at http://www.vogella.com/tutorials/EclipseTycho/article.html#removing-compiler-warning-messages-from-the-build I created a build for an update site but I ignore how to launch it from Eclipse. The only idea I have so far is to create a product configuration.
Best,
Miguel
