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.

Creating a generic OSGi bundle using WSO2 Carbon Bundle Archetype

You can create a generic OSGi bundle using one command with WSO2 Carbon Bundle Archetype.
Even though the name is WSO2 Carbon Bundle Archetype which has been published to maven central, this is a generic OSGi bundle.

Eg:
Execute the following command. The groupID of the archetype is org.wso2.carbon,
The artifactID of the archetype is org.wso2.carbon.archetypes.bundle  and the version of the archetype is  5.0.0

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


 This will create a project with the following structure.

org.sample.project
├── pom.xml
└── src
    ├── main
    │   └── java
    │       └── org
    │           └── sample
    │               └── project
    │                   ├── Greeter.java
    │                   └── internal
    │                       └── Activator.java
    └── test
        └── java
            └── org
                └── sample
                    └── project
                        └── GreeterTest.java

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