kie-maven-plugin: Make use of project dependencies to avoid their declaration inside kie-maven-plugin ----------------------------------------------------------------------------------------------------- Key: DROOLS-1762 URL: https://issues.redhat.com/browse/DROOLS-1762 Project: Drools Issue Type: Bug Components: build Reporter: Matej Čimbora Assignee: Massimiliano Dessi Priority: Major Attachments: dinnerparty.zip Suppose I use a guided decision table, which contains a custom Planner RHS IAction (e.g. [ActionSimpleConstraintMatch|https://github.com/kiegroup/optaplanner/blob/...]). The Planner IAction is located in the following module: {code:xml} <dependency> <groupId>org.optaplanner</groupId> <artifactId>optaplanner-workbench-models-datamodel-api</artifactId> </dependency> {code} My project depends on the optaplanner-workbench-models-datamodel-api module, so does kie-maven-plugin, see the [link|https://github.com/kiegroup/droolsjbpm-integration/blob/master/kie-m...]. If I remove the dependency from kie-maven-plugin, the build of my project fails with the following error: {code:xml} [ERROR] Failed to execute goal org.kie:kie-maven-plugin:8.0.0-SNAPSHOT:build (default-build) on project dinnerparty: Execution default-build of goal org.kie:kie-maven-plugin:8.0.0-SNAPSHOT:build failed: [ERROR] ---- Debugging information ---- [ERROR] cause-exception : com.thoughtworks.xstream.mapper.CannotResolveClassException [ERROR] cause-message : org.optaplanner.workbench.models.datamodel.rule.ActionSimpleConstraintMatch [ERROR] class : java.util.ArrayList [ERROR] required-type : java.util.ArrayList [ERROR] converter-type : com.thoughtworks.xstream.converters.collections.CollectionConverter [ERROR] path : /decision-table52/actionCols/org.drools.workbench.models.guided.dtable.shared.model.BRLActionColumn/definition/org.optaplanner.workbench.models.datamodel.rule.ActionSimpleConstraintMatch [ERROR] class[1] : org.drools.workbench.models.guided.dtable.shared.model.BRLActionColumn [ERROR] converter-type[1] : com.thoughtworks.xstream.converters.reflection.ReflectionConverter [ERROR] class[2] : org.drools.workbench.models.guided.dtable.shared.model.GuidedDecisionTable52 [ERROR] version : 1.4.10 [ERROR] ------------------------------- {code} I tried to load the org.optaplanner.workbench.models.datamodel.rule.ActionSimpleConstraintMatch class inside org.drools.workbench.models.guided.dtable.backend.GuidedDTXMLPersistence using getClass().getClassLoader().loadClass("org.optaplanner.workbench.models.datamodel.rule.ActionSimpleConstraintMatch"), leading to ClassNotFoundException. Expected behavior: Be able to use external classes in a kie project without the need to declare them directly in kie-maven-plugin. It should be enough to declare those dependencies in the project that I'm building. Attaching a reproducer (dinnerparty.zip). Should build fine out of the box. Now try to make a local build of kie-maven-plugin with org.optaplanner:optaplanner-workbench-models-datamodel-api dependency removed. Build dinnerparty project again, the issue described above should pop up.
