MTJ build properties support doesn't correctly account for non-MTJ projects, leaving problems in the error log with the above exception. The exception stack trace is below: java.lang.IllegalArgumentException: Invalid MTJ Project. at org.eclipse.mtj.internal.core.build.MTJBuildProperties.<init>(Unknown Source) at org.eclipse.mtj.internal.core.build.MTJBuildProperties.getBuildProperties(Unknown Source) at org.eclipse.mtj.internal.core.util.MTJBuildPropertiesResourceListener.updateBuildProperties(Unknown Source) at org.eclipse.mtj.internal.core.util.MTJBuildPropertiesResourceListener.resourceChanged(Unknown Source) at org.eclipse.core.internal.events.NotificationManager$2.run(NotificationManager.java:291) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.NotificationManager.notify(NotificationManager.java:285) at org.eclipse.core.internal.events.NotificationManager.broadcastChanges(NotificationManager.java:149) at org.eclipse.core.internal.resources.Workspace.broadcastPostChange(Workspace.java:327) at org.eclipse.core.internal.resources.Workspace.endOperation(Workspace.java:1181) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1984) at org.eclipse.ui.actions.WorkspaceModifyOperation.run(WorkspaceModifyOperation.java:118) at org.eclipse.jface.operation.ModalContext.runInCurrentThread(ModalContext.java:464) at org.eclipse.jface.operation.ModalContext.run(ModalContext.java:372) at org.eclipse.jface.wizard.WizardDialog.run(WizardDialog.java:1008) at org.eclipse.pde.internal.ui.wizards.plugin.NewPluginProjectWizard.performFinish(NewPluginProjectWizard.java:113) at org.eclipse.jface.wizard.WizardDialog.finishPressed(WizardDialog.java:811) at org.eclipse.jface.wizard.WizardDialog.buttonPressed(WizardDialog.java:430) at org.eclipse.jface.dialogs.Dialog$2.widgetSelected(Dialog.java:624) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:234) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1234) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3540) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3159) at org.eclipse.jface.window.Window.runEventLoop(Window.java:825) at org.eclipse.jface.window.Window.open(Window.java:801) at org.eclipse.ui.actions.NewProjectAction.run(NewProjectAction.java:117) at org.eclipse.jface.action.Action.runWithEvent(Action.java:498) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:584) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:501) 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:1234) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3540) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3159) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2601) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2565) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2399) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:669) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:662) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:369) 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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383)
Added a check to the MTJBuildPropertiesResourceListener class to prevent this error from occurring any more.
