OSGi package not running: missing osgi.wiring.package requirement; > & (osgi.wiring.package = org.apache.felix.dm)
I am trying to follow "Build Modular Cloud Applications with OSGi". In the third chapter of the book "Building Your First OSGi Application", the author describes how to create a simple OSGi application with a service in eclipse using bndtools.
Below is a screenshot of my classes and configurations.
The problem I am facing is
'! failed to resolve packages: [Agenda.service.simple-0.0.1 Installed limitation in package Agenda.service.simple [9]: Unable to resolve 9.0: missing requirement [9.0] osgi.wiring.package; (& Amp ;! (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 sometimes fails to enter correctly. But in the end when this package state looks like

Your Agenda.service.simple package looks for a package that exports the version of org.apache.felix.dm between 3.0.0 and 4.0.0, but it only finds version 4.0.1, which is Apache Felix Export Dependency Manager.
This can usually be caused by compiling against a different version of felix than you are doing.

This can usually be caused by compiling against a different version of felix than you are doing.
However, this could be caused by Bndtools picking the lowest version (in the specified version range) for buildpath dependencies and the highest version (in the specified version range) for runbundles.
In your case, no ranges are specified, so the version of org.apache.felix.dependencymanager version 3.1.0 will be used for the build path and 4.0.1 to run your application.
To use version 4 of the dependency manager, you can change the build path entry:
org.apache.felix.dependencymanager;version='[4,5)'
Or, to use version 3 at runtime, you change the -runbundles options to
org.apache.felix.dependencymanager;version='[3,4)',\
org.apache.felix.dependencymanager.shell;version='[3,4)',\

I am also reading the book above. I had the same problem when trying to run the project. This issue occurs because we are manually providing dependency manager .jars
our project, which in turn conflicts with the version .jar
required for the project.
I did a fresh Eclipse setup in advanced mode using Amdatu Blueprint and was able to get the current project. Installation details can be obtained from the following link:
