[jboss-jira] [JBoss JIRA] (DROOLS-2773) NPE when creating a new KieScanner

[Raphael Bowen Giudice (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-2773?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raphael Bowen Giudice updated DROOLS-2773:
------------------------------------------
    Description: 
When creating a new *KieScanner*, a *NullPointerException*  is thrown. Here's the code where the *KieScanner* is created:

{code:java}
final KieServices kieServices = KieServices.Factory.get();

final KieContainer kieContainer = kieServices.newKieContainer(
    kieServices.newReleaseId("mygroup", "rules", "1.0-SNAPSHOT"));


final KieScanner kieScanner = kieServices.newKieScanner(kieContainer);
{code}

The method *indexArtifacts* in the *KieRepositoryScannerImpl* class, tries to index all the Maven artefacts.In my case, the artefact *sun.jdk:jconsole:jdk* cannot be resolved, which causes the *NullPointerException* in the line 399:

{code:java}
private Map<ReleaseId, DependencyDescriptor> indexArtifacts() {
    Map<ReleaseId, DependencyDescriptor> depsMap = new HashMap<ReleaseId, DependencyDescriptor>();
    for (DependencyDescriptor dep : artifactResolver.getAllDependecies()) {
        if ( !"test".equals(dep.getScope()) && !"provided".equals(dep.getScope()) && !"system".equals(dep.getScope()) ) {
            Artifact artifact = artifactResolver.resolveArtifact(dep.getReleaseId());
            log.debug( artifact + " resolved to  " + artifact.getFile() ); // NPE happens here.
            if (isKJar(artifact.getFile())) {
                depsMap.put(adapt( dep.getReleaseIdWithoutVersion() ), new DependencyDescriptor(artifact));
            }
        } else {
            log.debug("{} does not need to be resolved because in scope {}", dep, dep.getScope());
        }
    }
    return depsMap;
}
{code}

The curious part is that the *sun.jdk:jconsole:jdk* artefact is not declared in any of my projects or dependencies, as far as I could investigate.

Here's the NPE stack trace:
