Creating a Carbon Component using WSO2 Carbon Component Archetype

A Carbon Component is an OSGi bundle which has a dependency on Carbon Kernel.
Using WSO2 Carbon Component Archetype which has been published to maven central, you can create a simple Carbon Component with one command.

Eg:
mvn archetype:generate -DarchetypeGroupId=org.wso2.carbon -DarchetypeArtifactId=org.wso2.carbon.archetypes.component -DarchetypeVersion=5.0.0  -DgroupId=org.sample -DartifactId=org.sample.project -Dversion=1.0.0 -Dpackage=org.sample.project


Above command will create a Carbon Component with the following structure.

org.sample.project
├── pom.xml
└── src
    └── main
        └── java
            └── org
                └── sample
                    └── project
                        ├── GreeterImpl.java
                        ├── Greeter.java
                        └── internal
                            ├── DataHolder.java
                            └── ServiceComponent.java

This Carbon Component consumes an OSGi service which is exposed from Carbon Core and also registers an OSGi service of its own.

If you do not pass the parameters for the project then the default values will be applied.

You can find the source for this archetype here.
