First, we create a directory hello-world-SE-SU-SA and open a command line in this folder. Now we execute the following command (it has to be one line but was split to be readable):

mvn

archetype:create

-DarchetypeGroupId=org.apache.servicemix.tooling

-DarchetypeArtifactId=servicemix-service-engine

-DarchetypeVersion=3.0-incubating

-DgroupId=org.

-DartifactId=hello-world-SE

Code Block


color test mvn archetype:create -DarchetypeGroupId=org.apache.servicemix.tooling -DarchetypeArtifactId=servicemix-service-engine
-DarchetypeVersion=3.0-incubating -DgroupId=org.apache.servicemix.samples.helloWorldSE -DartifactId=hello-world-SE

The first three parameters identify the maven 2 archetype to use, while the last two parameters define the generated maven 2 project. The version information "3.0-incubating" may have to be changed; a look at any of ServiceMix' pom.xml reveals the version to use. Maven uses the group ID (printed in pink) as default Java package (see Defaulting package to group ID: in output below as well), thus invalid characters like minus, percent etc. must be avoided or a custom package name has to be given as parameter. The output looks like this (only relevant information preserved):

Doing automated testing of the code is possible as well. As ServiceMix' root POM disables testing, it has to be activated for the subprojects that shall be tested.
