karaf-maven-plugin : filter by dependency scope?

[Andrei Pozolotin]

    Jean-Baptiste:

    in karaf-maven-plugin 3.0.0-SNAPSHOT,

    the goal features-generate-descriptor currently
    collects dependencies from all maven scopes (even test:
    wrap:mvn:junit/junit/4.8.2)

    in the code of GenerateDescriptrMojo.java there seems to be a check
    for "runtime" scope
    but in one execution path only (not all cases covered);

    what am I missing? how can I filter by dependency scope?

    Thank you,

    Andrei
