Hi, Wrap is a protocol that "translate" a regular jar as an OSGi bundle at runtime. So, you need wrap in your feature if you use non bundle jar.
Wrap is provided by the standard features repository. So, if your example0-bundle is really a bundle (meaning that you have the OSGi headers in the MANIFEST), you don’t need wrap. If you need wrap (it seems to be the case as example2-plugin is not a bundle), you need the wrap feature. This feature is provided by the Karaf standard features repository. So, you have either to add standard features repo in <repository/> tag, or add this feature repo in your pom where you create the kar. NB: it’s always better to create the features XML by hand (more efficient).
