Hi,

Is there a way to get the dependencies of an Installable Unit without creating a partial mirror of a p2 repository?

Thanks,
Orlando

Hi

do you mean running Junit Plug-in tests with the target platform
populated with such plugins?

Hi Lorenzo,

The use case is a command-line tool which executes a JVM-based scripting language. The tool is given a set of bundles as command-line arguments, and needs to make the classes and resources of those bundles accessible from within the script.

I have this working by running Maven/Tycho in the background (packaging=eclipse-repository, add bundles to category.xml), getting the jar file names from the created p2 repo, and then invoking a new JVM (classpath populated) to run the actual script.

Since Mave/Tycho takes 20-30 seconds to run, I cache the result per bundle set.

It would be nice, if Tycho or p2 provided an API to access this kind of dependency information.
