Chapter 6. Creating a self-contained Red Hat Decision Manager Spring Boot JAR file

Procedure

1. Add the following properties to your Spring Boot application application.properties file:

   kieserver.classPathContainer=true
   kieserver.autoScanDeployments=true

   Expand

   Parameter	Values	Description
   kieserver.classPathContainer	true, false	When set to true, KIE Server uses the class loader used by the container to load KJAR files and their dependencies.
   kieserver.autoScanDeployments	true, false	When set to true, KIE Server scans and deploys all KJAR files available in the Spring Boot application, whether they are declared programmatically or through the Maven plug-in.

   Show more

   When both of these properties are set to true, the Spring Boot KIE Server automatically scans for deployable artifacts that are packaged within the Spring Boot application using the package-dependencies-kjar Maven goal of the kie-maven-plugin plug-in.

2. Add the following Maven plug-in in the Spring Boot service/pom.xml file where <GROUP_ID>, <ARTIFACT_ID>, and <VERSION> are the group, artifact, and version (GAV) of an artifact that your project uses. These artifacts are located in the Spring Boot project kjar/pom.xml file.

   Note

   You can add more than one version of an artifact.

     <build>
       <plugins>
         <plugin>
           <groupId>org.kie</groupId>
           <artifactId>kie-maven-plugin</artifactId>
           <version>${version.org.kie}</version>
           <executions>
             <execution>
               <id>copy</id>
               <phase>prepare-package</phase>
               <goals>
                 <goal>package-dependencies-kjar</goal>
               </goals>
             </execution>
           </executions>
           <configuration>
             <artifactItems>
               <artifactItem>
                 <groupId><GROUP_ID></groupId>
                 <artifactId><ARTIFACT_ID>/artifactId>
                 <version><VERSION></version>
               </artifactItem>
             </artifactItems>
           </configuration>
         </plugin>
       <plugins>
     <build>

   The artifacts required to run the KJAR will be resolved at build time.

   The following example adds two version of the Evaluation artifact:

     <build>
       <plugins>
         <plugin>
           <groupId>org.kie</groupId>
           <artifactId>kie-maven-plugin</artifactId>
           <version>${version.org.kie}</version>
           <executions>
             <execution>
               <id>copy</id>
               <phase>prepare-package</phase>
               <goals>
                 <goal>package-dependencies-kjar</goal>
               </goals>
             </execution>
           </executions>
           <configuration>
             <artifactItems>
               <artifactItem>
                 <groupId>com.myspace</groupId>
                 <artifactId>Evaluation</artifactId>
                 <version>1.0.0-SNAPSHOT</version>
               </artifactItem>
               <artifactItem>
                 <groupId>com.myspace</groupId>
                 <artifactId>Evaluation</artifactId>
                 <version>2.0.0-SNAPSHOT</version>
               </artifactItem>
             </artifactItems>
           </configuration>
         </plugin>
       <plugins>
     <build>

3. To build the self-contained Spring Boot image, enter the following command in the service directory:

   maven install
