[ https://issues.jboss.org/browse/DROOLS-1051?page=com.atlassian.jira.plugi... ] Matteo Mortari commented on DROOLS-1051: ---------------------------------------- Description of proposed patch. In {{KieRepositoryScannerImpl}} : {code} private Map<ReleaseId, DependencyDescriptor> indexAtifacts(ArtifactResolver artifactResolver) { Map<ReleaseId, DependencyDescriptor> depsMap = new HashMap<ReleaseId, DependencyDescriptor>(); for (DependencyDescriptor dep : artifactResolver.getAllDependecies()) { Artifact artifact = artifactResolver.resolveArtifact(dep.getReleaseId()); log.debug( artifact + " resolved to " + artifact.getFile() ); if (isKJar(artifact.getFile())) { depsMap.put(dep.getReleaseIdWithoutVersion(), new DependencyDescriptor(artifact)); } } return depsMap; } {code} problem is that if the dependency "dep" is not resolvable at runtime, the method {{artifactResolver.resolveArtifact(...)}} will return a null, and in turn a NPE, and in turn will fail the initialization of the KieScanner. Proposal is to null guard the rest of the above mentioned code - if the variable "artifact" is not resolved, not considered as a KJar. The ideal would be to have also the scope in the dependency/artifact information, so to check for this specifically, but frankly couldn't locate this data to propose a better patch for now - in case just reject it and let me know a few pointers I'm keen in getting it corrected because we have this issue on our projects. Many thanks. ps: with the proposed patch: {code} 2016-02-03 18:09:02,278 INFO [com.acme.run_test_deps.App] (main) start 2016-02-03 18:09:02,306 DEBUG [org.drools.compiler.kie.builder.impl.KieRepositoryImpl] (main) KieModule Lookup.
