If you specify your own <Include-Resource> instruction, this will replace the generated one. To include the generated list of Maven resources in your own <Include-Resource> instruction just add {maven-resources} in your list.

The <Import-Package> instruction is a list of packages that are required by the bundle's contained packages. The default for this header is "*", resulting in importing all referred packages. This header rarely has to be explicitly specified. However, in certain cases when there is an unwanted import, such an import can be removed by using a negation package pattern. The package patterns work in the same way as for <Export-Package>, which means they are ordered. For example, if you wanted to import all packages except org.foo.impl you would specify "!org.foo.impl,*"
