Jean-Baptiste Onofré created KARAF-4118:
-------------------------------------------

             Summary: Command service declaration doesn't work
                 Key: KARAF-4118
                 URL: https://issues.apache.org/jira/browse/KARAF-4118
             Project: Karaf
          Issue Type: Bug
          Components: karaf-shell
    Affects Versions: 4.0.3, 4.0.2
            Reporter: Jean-Baptiste Onofré
            Assignee: Jean-Baptiste Onofré


Before Karaf 4, it was possible to define command by "declaration".

For instance, having a simple class like this:

{code}
package net.nanthrax.test.shell;

public class HelloCommand {

    public String hello() {
        return "hello";
    }

}
{code}

It was possible to "declare" a command (for instance using blueprint):

{code}
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">

    <bean id="helloCommand" class="net.nanthrax.test.shell.HelloCommand"/>

    <service ref="helloCommand" auto-export="class-hierarchy">
        <service-properties>
            <entry key="osgi.command.scope" value="hello"/>
            <entry key="osgi.command.function">
                <array>
                    <value>hello</value>
                </array>
            </entry>
        </service-properties>
    </service>

</blueprint>
{code}

However, in Karaf 4, the command is not found.

The cause comes from the org.apache.karaf.shell.compat.CommandTracker: if the class doesn't implement one of the two interfaces (org.apache.karaf.shell.commands.CommandWithAction or org.apache.felix.gogo.commands.CommandWithAction interface), the command is not register.

So basically, I gonna add the case where the class doesn't implement any interface ;)
