Bug 122176 Invalid project description when creating new project in default location when using NewJavaProjectWizardPage
When installing Parasoft Jtest 7.5 into Eclipse 3.2 M4, File > New > Jtest Example Project doesn't work when using the default location. I will attach a stack trace. This feature works in Eclipse 3.1.1, and I believe it also worked in Eclispe 3.2 M3. I've only tested it so far on Windows XP SP2. I've identified the problem in BuildPathsBlock.createProject(...): public static void createProject(IProject project, URI locationURI, IProgressMonitor monitor) throws CoreException { ... IProjectDescription desc= project.getWorkspace().newProjectDescription(project.getName()); if (locationURI != null && ResourcesPlugin.getWorkspace().getRoot().getLocationURI().equals(locationURI)) { locationURI= null; } desc.setLocationURI(locationURI); The locationURI is derived in NewJavaProjectWizardPage.java line 303 using IPath.toFile().toURI(), and can be for example: file:/C:/temp/workspace/ But ResourcesPlugin.getWorkspace().getRoot().getLocationURI() is: file:/C:/temp/workspace Hence, since they are not "equal", locationURI is not set to null, as is the expected behavior. Later in LocationValidator.validateProjectLocationURI(...) line 326 is when the failure status is created: if (FileUtil.isOverlapping(location, defaultDefaultLocation.toFile().toURI())) This problem does not appear in Eclipse 3.1.1, because only IPath's are being compared, not URI's: public static void createProject(IProject project, IPath locationPath, IProgressMonitor monitor) throws CoreException { ... if (Platform.getLocation().equals(locationPath)) { You might be able to fix this bug by just removing any slash at the end of the URI before calling equals. But maybe a more clever equals is required here.
