Receiving FileNotFoundException when Openning Mapping File in a multiple-source-folder project ---------------------------------------------------------------------------------------------- Key: HBX-1085 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1085 Project: Hibernate Tools Issue Type: Bug Components: consoleconfiguration Affects Versions: 3.2LATER Environment: Windows XP SP3 JDK 1.6.0_01 Eclipse 3.4.0 (Ganymede) HibernateTools plugin 3.2.4 nightly build (HibernateTools-3.2.4.200808270817-nightly) Reporter: Thai I received the following exception when Openning Mapping File from Hibernate perspective: java.io.FileNotFoundException: F:\projects\bizservice\src\main\filtered-resources\org\openbiz\bizservice\domain\User.hbm.xml (The system cannot find the path specified) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at org.hibernate.eclipse.console.actions.OpenFileActionUtils.getDocument(OpenFileActionUtils.java:233) at org.hibernate.eclipse.console.actions.OpenFileActionUtils.rootClassInResource(OpenFileActionUtils.java:98) at org.hibernate.eclipse.console.actions.OpenFileActionUtils.elementInResource(OpenFileActionUtils.java:86) at org.hibernate.eclipse.console.actions.OpenFileActionUtils.getResource(OpenFileActionUtils.java:282) at org.hibernate.eclipse.console.actions.OpenMappingAction.run(OpenMappingAction.java:120) at org.hibernate.eclipse.console.actions.OpenMappingAction.run(OpenMappingAction.java:96) at org.hibernate.eclipse.console.actions.OpenMappingAction.run(OpenMappingAction.java:71) at org.eclipse.ui.actions.BaseSelectionListenerAction.runWithEvent(BaseSelectionListenerAction.java:168) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:583) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:500) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:411) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2382) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2346) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2198) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:493) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:488) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:382) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) at org.eclipse.equinox.launcher.Main.main(Main.java:1212) I find out the root cause in the following class org.hibernate.eclipse.console.actions.OpenFileActionUtils (lines 273-282) for (int i = 0; i < packageFragmentRoots.length && resource == null; i++) { //search in source folders. if (packageFragmentRoots[i].getClass() == PackageFragmentRoot.class) { IPackageFragmentRoot packageFragmentRoot = packageFragmentRoots[i]; IPath path = packageFragmentRoot.getPath().append(file.getValue()); resource = ResourcesPlugin.getWorkspace().getRoot().getFile(path); } } if (resource != null && elementInResource(consoleConfiguration, resource, element)) return resource; The code assumes that if resource variable is not null, then the corresponding file exists at that location. In fact, when the file doesn't exist, the method org.eclipse.core.internal.resources.Container.getFile(..) might still return a not-null value (see http://mobius.inria.fr/eclipse-doc/org/eclipse/core/resources/IContainer....). As a result, a not-null file path will be passed to OpenFileActionUtils.elementInResource(..), and a FileNotFoundException will be thrown. * Note that my project contains more than one source folder. This issue may not happen on one-source-folder project.
