Jesper Skov [https://community.jboss.org/people/jskovjyskebankdk] created the discussion "CDI fails when adding a new folder" To view the discussion, visit: https://community.jboss.org/message/780126#780126 -------------------------------------------------------------- We have a project where the CDI builder tanks when creating a new empty folder. I haven't looked in earnest at the project to see if it is setup in some weird and wonderful way that actively encourages that NPE. But if so, it could probably be presented nicer :) !MESSAGE Errors running builder 'CDI (Context and Dependency Injection) Builder' on project 'jb.it.jquery.ext.web'. !STACK 0 java.lang.NullPointerException      at org.jboss.tools.common.java.impl.AnnotationDeclaration.validateNamedValue(AnnotationDeclaration.java:136)      at org.jboss.tools.common.java.impl.AnnotationDeclaration.validateNamedValue(AnnotationDeclaration.java:129)      at org.jboss.tools.common.java.impl.AnnotationDeclaration.resolveMemberValue(AnnotationDeclaration.java:119)      at org.jboss.tools.common.java.impl.AnnotationDeclaration.setDeclaration(AnnotationDeclaration.java:50)      at org.jboss.tools.cdi.internal.core.impl.definition.AbstractMemberDefinition.addAnnotation(AbstractMemberDefinition.java:112)      at org.jboss.tools.cdi.internal.core.impl.definition.AbstractMemberDefinition.init(AbstractMemberDefinition.java:104)      at org.jboss.tools.cdi.internal.core.impl.definition.MethodDefinition.init(MethodDefinition.java:61)      at org.jboss.tools.cdi.internal.core.impl.definition.AbstractMemberDefinition.setAnnotatable(AbstractMemberDefinition.java:64)      at org.jboss.tools.cdi.internal.core.impl.definition.MethodDefinition.setMethod(MethodDefinition.java:48)      at org.jboss.tools.cdi.internal.core.impl.definition.TypeDefinition.init(TypeDefinition.java:70)      at org.jboss.tools.cdi.internal.core.impl.definition.AbstractMemberDefinition.setAnnotatable(AbstractMemberDefinition.java:64)      at org.jboss.tools.cdi.internal.core.impl.definition.AbstractTypeDefinition.setType(AbstractTypeDefinition.java:69)      at org.jboss.tools.cdi.internal.core.scanner.CDIBuilderDelegate.build(CDIBuilderDelegate.java:79)      at org.jboss.tools.cdi.internal.core.scanner.CDIBuilderDelegate.build(CDIBuilderDelegate.java:48)      at org.jboss.tools.cdi.core.CDICoreBuilder.invokeBuilderDelegates(CDICoreBuilder.java:326)      at org.jboss.tools.cdi.core.CDICoreBuilder.fullBuild(CDICoreBuilder.java:261)      at org.jboss.tools.cdi.core.CDICoreBuilder.build(CDICoreBuilder.java:221)      at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:728)      at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42)      at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:199)      at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:239)      at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:292)      at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42)      at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:295)      at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:351)      at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:374)      at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:143)      at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:241)      at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53) -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/780126#780126] Start a new discussion in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
