I am building OSGi bundle (in NetBeans 8.2), but I need external maven dependiencies, but once I add them into my pom, I cannot run the bundle anymore.
My entire pom looks like this:

The bundle is builded just fine, but when I try to start the bundle I get this error:
[java] org.osgi.framework.BundleException: Unresolved constraint in bundle org.apache.commons.commons-dbcp2 [5]: Unable to resolve 5.0: missing requirement [5.0] osgi.wiring.package; (&(osgi.wiring.package=javax.transaction)(version>=1.1.0))

EDIT: Added entire pom.xml file, I have tried to add all packages inside as suggested in similar posts but that did not helped.
Also tried to add into my pom, cannot see a difference here.
And lastly I tried adding tags, but that did not help either.
Majority of the pom file was generated by netbeans itself (Maven OSGi Bundle - default template with generated activator class).
Solved by adding this into into pom:
<configuration>
<instructions>
<Bundle-Activator>myProject.Activator</Bundle-Activator>
<Import-Package>
*;resolution:=optional
</Import-Package>
</instructions>
</configuration>
Apparently there might be some problem, is you are not directly importing packages into classes in the bundle. Not exactly sure why it happens but here is the source:
