9.3. Adding Maven dependencies for Red Hat Decision Manager

Procedure

1. Declare the Red Hat Business Automation BOM in the pom.xml file:

   <dependencyManagement>
    <dependencies>
     <dependency>
      <groupId>com.redhat.ba</groupId>
      <artifactId>ba-platform-bom</artifactId>
      <version>7.5.1.redhat-00001</version>
      <type>pom</type>
      <scope>import</scope>
     </dependency>
    </dependencies>
   </dependencyManagement>
   <dependencies>
   <!-- Your dependencies -->
   </dependencies>

2. Declare dependencies required for your project in the <dependencies> tag. After you import the product BOM into your project, the versions of the user-facing product dependencies are defined so you do not need to specify the <version> sub-element of these <dependency> elements. However, you must use the <dependency> element to declare dependencies which you want to use in your project.

3. For standalone projects that are not authored in Business Central, specify all dependencies required for your projects. In projects that you author in Business Central, the basic decision engine dependencies are provided automatically by Business Central.

   • For a basic Red Hat Decision Manager project, declare the following dependencies, depending on the features that you want to use:

   • For a basic Red Hat Decision Manager project, declare the following dependencies:

     Embedded decision engine dependencies

     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-compiler</artifactId>
     </dependency>
     
     <!-- Dependency for persistence support. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-persistence-jpa</artifactId>
     </dependency>
     
     <!-- Dependencies for decision tables, templates, and scorecards.
     For other assets, declare org.drools:business-central-models-* dependencies. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-decisiontables</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-templates</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-scorecards</artifactId>
     </dependency>
     
     <!-- Dependency for loading KJARs from a Maven repository using KieScanner. -->
     <dependency>
       <groupId>org.kie</groupId>
       <artifactId>kie-ci</artifactId>
     </dependency>

   • To use the Decision Server, declare the following dependencies:

     Client application Decision Server dependencies

     <dependency>
       <groupId>org.kie.server</groupId>
       <artifactId>kie-server-client</artifactId>
     </dependency>

   • To create a remote client for Red Hat Decision Manager, declare the following dependency:

     Client dependency

     <dependency>
       <groupId>org.uberfire</groupId>
       <artifactId>uberfire-rest-client</artifactId>
     </dependency>

   • When creating a JAR file that includes assets, such as rules and process definitions, specify the packaging type for your Maven project as kjar and use org.kie:kie-maven-plugin to process the kjar packaging type located under the <project> element. In the following example, ${kie.version} is the Maven library version listed in What is the mapping between Red Hat Decision Manager and the Maven library version?:

     <packaging>kjar</packaging>
     <build>
      <plugins>
       <plugin>
        <groupId>org.kie</groupId>
        <artifactId>kie-maven-plugin</artifactId>
        <version>${kie.version}</version>
        <extensions>true</extensions>
       </plugin>
      </plugins>
     </build>
