Getting ready

The easiest way for you to create a Helidon MP project is by using a Maven archetype. Just execute this command:

mvn archetype:generate -DinteractiveMode=false \
 -DarchetypeGroupId=io.helidon.archetypes \
 -DarchetypeArtifactId=helidon-quickstart-mp \
 -DarchetypeVersion=1.4.1 \
 -DgroupId=com.eldermoraes.ch08 \
 -DartifactId=ch08-mpopenapi \
 -Dpackage=com.eldermoraes.com.ch08.mpopenapi

So, your starter project will be in the ch08-mpopenapi folder:

cd ch08-mpopenapi

Before continuing, edit the pom.xml of this project and add one dependency:

<dependency>
   <groupId>org.eclipse.microprofile.openapi</groupId>
   <artifactId>microprofile-openapi-api</artifactId>
</dependency>

Now, we are ready to go!
