Question

I’m currently trying to implement a custom shell command for Felix using iPOJO. My sample implementation looks like:

import java.io.PrintStream;

import org.apache.felix.ipojo.annotations.Component;
import org.apache.felix.ipojo.annotations.Provides;
import org.apache.felix.shell.Command;

@Component(immediate = true)
@Provides
public class SampleCommand implements Command {


    @Override
    public String getName() {
        return "testcmd";
    }

    @Override
    public String getUsage() {
        return "testcmd";
    }

    @Override
    public String getShortDescription() {
        return "test command";
    }

    @Override
    public void execute(String line, PrintStream out, PrintStream err) {
        out.println("execute testcmd!");
    }

}

When I deploy the Bundle on Felix, my SampleCommand gets instantiated and the getName() gets called. But when I try to execute “testcmd” on the shell, I get:

gogo: CommandNotFoundException: Command not found: testcmd

Are there any further points I need to consider?

Based on the feedback given above by user1231484 and earcam, here a minimal working example:

import org.apache.felix.ipojo.annotations.Component;
import org.apache.felix.ipojo.annotations.Instantiate;
import org.apache.felix.ipojo.annotations.Provides;
import org.apache.felix.ipojo.annotations.ServiceProperty;
import org.apache.felix.service.command.Descriptor;

@Component(immediate = true)
@Instantiate
@Provides(specifications = ListComponentsCommand.class)
public class ListComponentsCommand {

    @ServiceProperty(name = "osgi.command.scope", value = "test")
    String scope;

    @ServiceProperty(name = "osgi.command.function", value = "{}")
    String[] function = new String[] { "test" };

    @Descriptor("test")
    public void test() {
        System.out.println("test!");
    }

}
