NPE in KieModuleMetaDataImpl in projects with invalid pom.xml ------------------------------------------------------------- Key: DROOLS-2166 URL: https://issues.jboss.org/browse/DROOLS-2166 Project: Drools Issue Type: Bug Reporter: Jan Hrcek Assignee: Mario Fusco When indexing assets in projects which have some problems with pom.xml (e.g. the parent of that pom can't be resolved), there's the following exception in server.log {code:java} 14:34:46,627 ERROR [stderr] (Thread-144) java.lang.NullPointerException 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.scanner.KieModuleMetaDataImpl.init(KieModuleMetaDataImpl.java:167) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.scanner.KieModuleMetaDataImpl.<init>(KieModuleMetaDataImpl.java:86) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.scanner.KieModuleMetaData$Factory.newKieModuleMetaData(KieModuleMetaData.java:60) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.backend.builder.core.Builder.getKieModuleMetaDataIgnoringErrors(Builder.java:593) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.backend.builder.service.BuildInfoImpl.getKieModuleMetaDataIgnoringErrors(BuildInfoImpl.java:46) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.datamodel.backend.server.cache.ProjectDataModelOracleBuilderProvider.newBuilder(ProjectDataModelOracleBuilderProvider.java:62) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.datamodel.backend.server.cache.LRUProjectDataModelOracleCache.makeProjectOracle(LRUProjectDataModelOracleCache.java:80) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.datamodel.backend.server.cache.LRUProjectDataModelOracleCache.assertProjectDataModelOracle(LRUProjectDataModelOracleCache.java:72) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.datamodel.backend.server.cache.LRUProjectDataModelOracleCache$Proxy$_$$_WeldClientProxy.assertProjectDataModelOracle(Unknown Source) 14:34:46,627 ERROR [stderr] (Thread-144) at org.kie.workbench.common.services.datamodel.backend.server.DataModelServiceImpl.getProjectDataModel(DataModelServiceImpl.java:91) {code} The root cause is that kieModule.getPomModel() [here|https://github.com/kiegroup/drools/blob/master/kie-ci/src/main/java/...] returns null, because pom model is [not created in this case|https://github.com/kiegroup/drools/blob/master/drools-compiler/src/m...] because it can't be parsed or can't be validated. In this case we should at least avoid many NPEs being shown in server.log by doing null check and doing nothing if getPomModel() returns null
