Chapter 16. Creating a Maven project for a Kogito microservice

Before you can begin developing Kogito microservices, you need to create a Maven project where you can build your assets and any other related resources for your application.

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 Quarkus

    $ mvn archetype:generate \
    -DarchetypeGroupId=org.kie.kogito \
    -DarchetypeArtifactId=kogito-quarkus-dm-archetype \
    -DgroupId=org.acme -DartifactId=sample-kogito \
    -DarchetypeVersion=1.5.0.redhat-00002 \
    -Dversion=1.0-SNAPSHOT

    On Spring Boot

    $ mvn archetype:generate \
    -DarchetypeGroupId=org.kie.kogito \
    -DarchetypeArtifactId=kogito-springboot-dm-archetype \
    -DgroupId=org.acme -DartifactId=sample-kogito \
    -DarchetypeVersion=1.5.0.redhat-00002 \
    -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 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 Quarkus, if you plan to run your application on OpenShift, you must also import the Quarkus smallrye-health extension for the liveness and readiness probes, as shown in the following example:

    SmallRye Health extension for 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 Quarkus:

    SmallRye Heath dependency for Quarkus applications on OpenShift

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

  3. Open or import the project in your VSCode IDE to view the contents.
