Hello, I am using Drools 6.1.0.Beta1 in a project with the following (shortened) pom.xml:
<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>de.test.configuration</groupId> <artifactId>someTest</artifactId> <version>0.7.0-SNAPSHOT</version> <packaging>jar</packaging> <name>droolsTest</name> <parent> <groupId>de.test</groupId> <artifactId>maven-parent</artifactId> <version>0.3</version> </parent> <dependencies> <!-- The Drools rule engine --> <dependency> <groupId>org.drools</groupId> <artifactId>drools-core</artifactId> <version>6.1.0.Beta1</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-compiler</artifactId> <version>6.1.0.Beta1</version> </dependency> <!-- getting maven artefacts --> <dependency> <groupId>org.kie</groupId> <artifactId>kie-ci</artifactId> <version>6.1.0.Beta1</version> </dependency> </dependencies> </project> For the internal maven, used within KIE/Drools, I have a separate settings.xml, which is configured with the property -Dkie.maven.settings.custom="X:\\droolsmaven\\settings.xml" The contents of this file are: <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd";> <localRepository>x:/droolsmaven/repository</localRepository> <profiles> <profile> <id>mavenDroolsProfile</id> <activation> <activeByDefault>true</activeByDefault> </activation> <repositories> <repository> <id>someRepo</id> <url>http://1.2.3.4</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>central</id> <url>http://repo1.maven.org/maven2</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> </profile> </profiles> </settings> In that local repository, the respective artifact used later is deployed, which is working, confirmed with a non-maven-project. Now, when trying running the following code within the maven project which is defined by the above mentioned pom, I get the errors mentioned after this code block: public class MainKieTest { public static void main(String[] args) { KieServices ks = KieServices.Factory.get(); KieRepository repository = ks.getRepository(); ReleaseId releaseId = ks.newReleaseId("de.test.package", "artifact", "1.0.1"); KieContainer kieContainer = ks.newKieContainer(releaseId); KieScanner kieScanner = ks.newKieScanner(kieContainer); kieScanner.scanNow(); } } The error is: DEBUG [main] (KieRepositoryImpl.java:92) - KieModule Lookup.

IMHO, this should not be, because the maven artifacts deployed for Drools, used at runtime, are independent from the artifacts used for building the project itself; those are needed at buildtime. Is this problem just a misconception of how I think Drools should work or is it an actual bug?
