I was looking for a small plugin for Eclipse that would allow to open windows explorer on currently selected resource from Package Explorer tree.
I know that Aptana Studio provides this functionality via context menu on the resource, but it has tons of other stuff that I am not interested to.
Are there other solutions?
Create a new Plug-In project using Eclipse PDE. Hook your bundle's Activator class into the Common Navigator API to receive selections for IResource. For each IResource selected, use the FileLocator to get a file URI, with which you can construct a java.io.File object. This can then be opened in the operating system's native file explorer using Java 6 Desktop integration:
if (Desktop.isDesktopSupported()) {
Desktop desktop = Desktop.getDesktop();
desktop.open(new File("C:/"));
}
