             Summary: kie ci regression: unable to resolve dependency of kjar during KB creation
                 Key: DROOLS-743
                 URL: https://issues.jboss.org/browse/DROOLS-743
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 6.2.0.Final
         Environment: Please notice it works OK with Drools 6.1.0.Final
Currently JDK8, Wildfly 8.2.0.Final.
            Reporter: Matteo Mortari
            Assignee: Mario Fusco


h5. Executive summary

With version 610Final using kie-ci, if the kjar KieModule had some pom dependency, say on a "object model" or reference package, the classes in the dependency artifact would be resolved correctly during knowledge base creation. However with 620Final, when the kjar KieModule is fetched and knowledge base creation starts, it seems like the kie-ci is no longer able to "see" the classes of this pom dependency.

This is a problem especially in all scenarios where different rule packages kjar KieModule defines rules based on a common library, "object model".

h5. Details and Reproducer

Suppose you have a library, object model, package reference .jar artifact, attached:
{{exercise_kie_ci-rules-objectmodel}}

Suppose you have a simple kjar project:
{{exercise_kie_ci-rules}}
with very simple rule
{code}
package com.acme.exercise_kie_ci_rules;

import com.acme.exercise_kie_ci_rules_objectmodel.AcmePojo;

rule "just test dependency of objectmodel"
no-loop
when
then
	AcmePojo pojo = new AcmePojo("Ciao");
	System.out.println("Simple rule for inserting pojo..."+pojo);
	insert(pojo);
end
{code}

You will notice in kjar pom the dependency is explicited and rule compilation works ok with kie-maven-plugin.

Now install them with:
mvn install the artifactId exercise_kie_ci-rules-objectmodel
mvn install the artifactId exercise_kie_ci-rules

Now deploy the {{exercise-kie-ci}} on WildFly:
IFF Drools version is 610Final works ok: 
{code}

{code}

Kindly notice line mentioning the artifact was kjar KieModule was resolved and correctly imported, an debug log line mentioning the very simple rule is available in the KB.

However, if you now switch the Drools version to 620Final in the {{exercise-kie-ci}} and redeploy to WildFly, it would no longer work:
{code}
19:23:09,524 ERROR [org.drools.compiler.kie.builder.impl.AbstractKieModule] (ServerService Thread Pool -- 54) Unable to build KieBaseModel:defaultKieBase
Error importing : 'com.acme.exercise_kie_ci_rules_objectmodel.AcmePojo'

   text=Error importing : 'com.acme.exercise_kie_ci_rules_objectmodel.AcmePojo']
{code}

I will attach reproducer.

Could you kindly advise, please?
As always, thank you.
Ciao
MM
