Ciao, with premise I'm not a Maven expert... I'm following now the new recommended version for 6.0 KIE project/module development as documented in [1] by generating a new maven archetype "quickstart" but if compared to the documentation I found, at least in my case, I had at a minimum to apply also the following in the pom.xml: A. the packaging must be changed to "kjar" B. if the project and the rules depend on an external library/maven artifact, say for instance the object model or domain model objects the rules will be based on, it is NOT enough to declare them in the pom.xml <dependencies>, but the exact same dependencies MUST ALSO be also declared within the kie-maven-plugin <plugin> <dependencies> as well.
Failing to do so, would imply that, respectively: A. when you run Maven with the default "mvn package" or "mvn deploy" etc, the kie-maven-plugin would not trigger B. kie-maven-plugin will fail the build because unable to resolve the "external" classes referenced in the .drl, with a message similar to [ERROR] Message [id=3, level=ERROR, path=package.drl, line=3, column=0 text=Unable to find class 'classname'] Questions are: 1. Is this correct, or I'm just complicating my life without noticing, and it is existing a simpler way, please? 2. Especially point #B, is this really the intended behavior, having to replicate the dependencies in the two parts of the pom.xml ? Thanks if somebody can feedback on this, Ciao MM I'm making reference to: [1] http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html_single/#KIEModuleIntroductionBuildingIntroductionSection For reference, here is an example pom.xml I'm using: <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>com.acme</groupId> <artifactId>my-rules</artifactId> <version>0.0.1</version> <!-- point #A, must set to kjar --> <packaging>kjar</packaging> <!-- ... --> <dependencies> <!-- maven artifact containing the object model or domain model objects the rules will be based on --> <dependency> <groupId>com.acme</groupId> <artifactId>object-model</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> </dependencies> <build> <finalName>my-rules</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <groupId>org.kie</groupId> <artifactId>kie-maven-plugin</artifactId> <version>6.0.0.Final</version> <extensions>true</extensions> <dependencies> <!-- point #B, the dependency must be repeated in here as well --> <dependency> <groupId>com.acme</groupId> <artifactId>object-model</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> </plugin> </plugins> <!-- The following is added to avoid Eclipse ERROR at the pom.xml line defining the kie-maven-plugin, by explicitly telling Eclipse to avoid run the plugin on Eclipse-build, leaving it trigger only when running Maven, eg "mvn package" or "mvn deploy", etc etc , see http://wiki.eclipse.org/M2E_plugin_execution_not_covered --> <pluginManagement> <plugins> <plugin> <groupId>org.eclipse.m2e</groupId> <artifactId>lifecycle-mapping</artifactId> <version>1.0.0</version> <configuration> <lifecycleMappingMetadata> <pluginExecutions> <pluginExecution> <pluginExecutionFilter> <groupId>org.kie</groupId> <artifactId>kie-maven-plugin</artifactId> <versionRange>[6.0.0,)</versionRange> <goals> <goal>build</goal> </goals> </pluginExecutionFilter> <action> <ignore /> </action> </pluginExecution> </pluginExecutions> </lifecycleMappingMetadata> </configuration> </plugin> </plugins> </pluginManagement> </build> <!-- ... --> </project>
