I have been trying to follow 'Building Modular Cloud Apps with OSGi'. In chapter 3 of the book 'Creating the first OSGi application' the author describes how to create a simple OSGi application with a service in eclipse with bndtools.

Below is the screenshot of my classes and configurations.

The problem I am facing is

'! could not resolve the bundles: [agenda.service.simple-0.0.1Unresolved constraint in bundle agenda.service.simple [9]: Unable to resolve 9.0: missing requirement [9.0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.felix.dm)(version>=3.0.0)(!(version>=4.0.0)))

] ! Failed to start bundle agenda.service.simple-0.0.1, exception Unresolved constraint in bundle agenda.service.simple [9]: Unable to resolve 9.0: missing requirement [9.0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.felix.dm)(version>=3.0.0)(!(version>=4.0.0))) ____________________________'

Also, when i try to issue a command in the gogo shell that also doesnt input corretly sometimes. But eventually when it does the bundle status looks like

g! lb gogo: CommandNotFoundException: Command not found: b

g! lb gogo: CommandNotFoundException: Command not found: llb

Your agenda.service.simple bundle is looking for a bundle that exports a version of org.apache.felix.dm between 3.0.0 and 4.0.0, but it is only finding the 4.0.1 version that the Apache Felix Dependency Manager exports.

Typically this would be caused by compiling against a different version of felix than you are running against.
