Add the Spring Milestone Repository

Due to the use of the spring-osgi-core milestone version we need to add the repository for that here.

Code Block
langxml

    <repositories>
        <repository>
            <id>spring-milestone</id>
            <name>Spring Portfolio Milestone Repository</name>

Loading the project in your IDE

We can now create the command class ListCommandHelloGShellCommand.java

titleConfigListHelloGShellCommand.java
langjava
package org.apache.servicemix.kernel.gshell.configsample;

import org.apache.servicemix.geronimokernel.gshell.supportcore.OsgiCommandSupport;

public class HelloGShellCommand extends OsgiCommandSupport {

    /* (non-Javadoc)
     * @see org.apache.geronimoservicemix.kernel.gshell.command.annotation.CommandComponent;

@CommandComponent(id="config:list", description="List the available configurations")
public class ListCommand extends OsgiCommandSupport {
core.OsgiCommandSupport#doExecute()
     */
    @Override
    protected Object doExecute() throws Exception {
        io.out.println("Executing ListHello command");
        return null;
    }

 Tip
titleUsing Java 5
If you see something like that:
 Code Block

[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Compilation failure
xxx/src/main/java/org/apache/servicemix/kernel/gshell/config/ListCommand.java:[6,1] annotations are not supported in -source 1.3
(try -source 1.5 to enable annotations)
@CommandComponent(id="config:list", description="List the available configurations")

that's because we forgot to enable Java 5. So let's add that to the pom:

osgi install -s mvn:org.apache.servicemix.kernelgshell.gshell/org.apache.servicemix.kernel.gshell.configsamples/gshell-commands/1.0-SNAPSHOT

If you run the help command, you should now see our new shell config sample.
Let's try running the command:
 Code Block
servicemix> sample/hello
Executing Hello command

and for the alias:
 Code Block

servicemix> sample/hiconfig list
Executing ListHello command

Yeah (smile)
