Hi Xilai,
the command annotations now comes from org.apache.karaf package. It was
already deprecated in K3 but still working.
Did you upgrade the completers as well ?

Hi,
The custom console commands we developed on karaf 2.x don’t work anymore
on the karaf 4.0
The code used on 2.x:
import org.apache.felix.gogo.commands.Command;
import org.apache.karaf.features.command.FeaturesCommandSupport;
@Command(scope = "test", name = "switch-abc", description = "test command")
public class TestComand extends FeaturesCommandSupport {
……
}
The code used on 4.0 (make changes following 4.0 api):
import org.apache.karaf.features.command.FeaturesCommandSupport;
import org.apache.karaf.shell.api.action.Command;
import org.apache.karaf.shell.api.action.lifecycle.Service;
@Command(scope = "test", name = "switch-abc", description = "test command")
@Service
public class TestComand extends FeaturesCommandSupport {
……
}
After install this command bundle into karaf 4, the ClassCastException
will be thrown:
