        Hi,

        can you please attach a sample project or give more information about the problem?

        Unfortunately, I cannot attach any test project, because I've tested only on my real project.

        There is a multi-module Maven project. Almost all modules are OSGi bundles (bundle packaging + maven-bundle-plugin). I've tried to configure scr-plugin in my root pom for all submodules. It works fine if I build only one submodule (even non-OSGI - normal JAR packaging). When I've tried to build whole project I've got above exception in a normal-JAR submodule.
