Annotation processor fails in Eclipse when evaluating custom constraints not defined in the current project ----------------------------------------------------------------------------------------------------------- Key: HV-293 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-293 Project: Hibernate Validator Issue Type: Bug Affects Versions: 4.1.0-Beta-1 Reporter: Gunnar Morling Assignee: Hardy Ferentschik In certain situations the AP fails when being integrated in Eclipse with the following exception: java.lang.AssertionError: Class org.hibernate.validator.constraints.impl.LengthValidator specified in @Constraint.validatedBy doesn't implement ConstraintValidator. at org.hibernate.validator.ap.util.ConstraintHelper.getConstraintValidatorSuperType(ConstraintHelper.java:497) at org.hibernate.validator.ap.util.ConstraintHelper.getSupportedType(ConstraintHelper.java:426) at org.hibernate.validator.ap.util.ConstraintHelper.getSupportedTypes(ConstraintHelper.java:402) at org.hibernate.validator.ap.util.ConstraintHelper.checkCustomConstraint(ConstraintHelper.java:356) at org.hibernate.validator.ap.util.ConstraintHelper.checkConstraint(ConstraintHelper.java:295) at org.hibernate.validator.ap.ConstraintAnnotationVisitor.checkConstraintAtField(ConstraintAnnotationVisitor.java:290) at org.hibernate.validator.ap.ConstraintAnnotationVisitor.visitVariableAsField(ConstraintAnnotationVisitor.java:174) at org.hibernate.validator.ap.ConstraintAnnotationVisitor.visitVariableAsField(ConstraintAnnotationVisitor.java:45) at javax.lang.model.util.ElementKindVisitor6.visitVariable(ElementKindVisitor6.java:199) at org.eclipse.jdt.internal.compiler.apt.model.VariableElementImpl.accept(VariableElementImpl.java:55) at org.hibernate.validator.ap.ConstraintValidationProcessor.process(ConstraintValidationProcessor.java:84) at org.eclipse.jdt.internal.compiler.apt.dispatch.RoundDispatcher.handleProcessor(RoundDispatcher.java:139) at org.eclipse.jdt.internal.compiler.apt.dispatch.RoundDispatcher.round(RoundDispatcher.java:121) at org.eclipse.jdt.internal.compiler.apt.dispatch.BaseAnnotationProcessorManager.processAnnotations(BaseAnnotationProcessorManager.java:159) at org.eclipse.jdt.internal.apt.pluggable.core.dispatch.IdeAnnotationProcessorManager.processAnnotations(IdeAnnotationProcessorManager.java:134) at org.eclipse.jdt.internal.compiler.Compiler.processAnnotations(Compiler.java:810) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:428) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:364) at org.eclipse.jdt.internal.core.builder.IncrementalImageBuilder.compile(IncrementalImageBuilder.java:321) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:301) at org.eclipse.jdt.internal.core.builder.IncrementalImageBuilder.build(IncrementalImageBuilder.java:134) at org.eclipse.jdt.internal.core.builder.JavaBuilder.buildDeltas(JavaBuilder.java:265) at org.eclipse.jdt.internal.core.builder.JavaBuilder.build(JavaBuilder.java:193) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) This happens, if the AP examines a constraint annotation, which is not defined in the currently built project itself, but is imported from some other JAR (e.g. @Length from HV): public class TestModel { @Length private String test; } The problem occurs, regardless whether the JAR containing the constraint is on the AP classpath or not. The AP works as expected when running on javac. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
