Bug 4121 JarExporter causes out of Sync (1GILQD5)
PA (8/17/01 2:03:29 PM) if you export a directory (project) and place the exported jar in the same directory (project) then you will get an out of sync message when you overwrite the exported jar-file the 2nd time. -> maybe the exported jar file should not include itself ? NOTES:
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/jarpackager/JarPackageWizardPage.java
return getPathFromText(fSourceNameField);
