回答1:
Do you have this bundle installed in your container (Felix) as well?
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.6.ga</version>
</dependency>
If not install it and then see what happens when you start your bundle.
回答2:
For missing requirement [Bundle-number] osgi.wiring.package, I added it as export-package in pom.xml, as mentioned below:
<Export-Package>
package for which error is thrown
</Export-Package>
and it worked. So if it throws the above error even after declaring it as dependency, export-package may help
