It's normal: there are some refactoring between 2.x and 3.x.
If you take a look in the command archetype, you can see:
https://git-wip-us.apache.org/repos/asf?p=karaf.git;a=blob_plain;f=archetypes/command/src/main/resources/archetype-resources/src/main/java/__command__.java;hb=karaf-3.0.x
You should extend OsgiCommandSupport.
Don't forget to import:
org.apache.felix.service.command
You can see the Karaf 3.x command style on Cellar 3.x.

Hi,
I've upgraded from karaf 2.x to 3.0.2 (with shell namesapce 1.1) and the
custom commands are not working anymore.
Here is a sample command:
import org.apache.karaf.shell.commands.Argument;
import org.apache.karaf.shell.commands.Command;
import org.apache.karaf.shell.console.AbstractAction;
@Command(scope = "my", name = "list", description = "a sample command")
public class ListCommand extendsAbstractAction {
@Argument(index = 0, name = "arg", description ="a sampleargument",
required = false, multiValued = false)
private Stringarg = null;
protected Object doExecute() throws Exception {
return new String[]{"Given parameter: ",arg == null ? "<not given>"
:arg};
}
}
and the blueprint config:
<command-bundle xmlns="http://karaf.apache.org/xmlns/shell/v1.1.0";>
<command>
<action class="my.sample.command.ListCommand" />
</command>
</command-bundle>
and finally the pom config:
<Import-Package>
org.apache.karaf.shell.commands,
org.apache.karaf.shell.console,
*
</Import-Package>
but the command installation fails with following message:
org.osgi.service.blueprint.container.ComponentDefinitionException:
org.osgi.service.blueprint.container.ComponentDefinitionException:Unable to

Am I missing anything here? any idea?
Thanks
