Chapter 3. Creating a Maven project for a Red Hat build of Kogito microservice

Procedure

1. In a command terminal, navigate to a local folder where you want to store the new project.

2. Enter the following command to generate a project within a defined folder:

   On Red Hat build of Quarkus

   $ mvn io.quarkus:quarkus-maven-plugin:create \
       -DprojectGroupId=org.acme -DprojectArtifactId=sample-kogito \
       -DprojectVersion=1.0.0-SNAPSHOT -Dextensions=kogito-quarkus

   On Spring Boot

   $ mvn archetype:generate \
       -DarchetypeGroupId=org.kie.kogito \
       -DarchetypeArtifactId=kogito-spring-boot-archetype \
       -DgroupId=org.acme -DartifactId=sample-kogito \
       -DarchetypeVersion=1.11.0.Final \
       -Dversion=1.0-SNAPSHOT

   This command generates a sample-kogito Maven project and imports the extension for all required dependencies and configurations to prepare your application for business automation.

   If you want to enable PMML execution for your project, add the following dependency to the pom.xml file in the Maven project that contains your Red Hat build of Kogito microservices:

   Dependency to enable PMML execution

   <dependency>
     <groupId>org.kie.kogito</groupId>
     <artifactId>kogito-pmml</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jpmml</groupId>
     <artifactId>pmml-model</artifactId>
   </dependency>

   On Red Hat build of Quarkus, if you plan to run your application on OpenShift, you must also import the smallrye-health extension for the liveness and readiness probes, as shown in the following example:

   SmallRye Health extension for Red Hat build of Quarkus applications on OpenShift

   $ mvn quarkus:add-extension -Dextensions="smallrye-health"

   This command generates the following dependency in the pom.xml file of your Red Hat Decision Manager project on Red Hat build of Quarkus:

   SmallRye Health dependency for Red Hat build of Quarkus applications on OpenShift

   <dependency>
     <groupId>io.quarkus</groupId>
     <artifactId>quarkus-smallrye-health</artifactId>
   </dependency>
