How to get resources path from an Eclipse plugin

Question

I am developing an Eclipse plugin using Eclipse Plugin-in-project where it will add a menu item in the toolbar.

My plugin project is depending on one file which is located in the same plugin project I want the path of that file.

Below is the sample code I have used to get the path:

Bundle bundle = Platform.getBundle("com.feat.eclipse.plugin");
URL fileURL = bundle.getEntry("webspy/lib/file.txt");
File file = null;
String path=null;
try {
    file = new File(FileLocator.resolve(fileURL).toURI());
    path = file.getAbsolutePath();
} catch (URISyntaxException e1) {
    e1.printStackTrace();
} catch (IOException e1) {
    e1.printStackTrace();
}

While running from Eclipse Run as > Eclipse Application it is giving me the correct path. But when I export my plugin as jar and add it in my Eclipse plugins folder its not giving me the correct path.

Please help me to resolve this!

Use:

URL url = FileLocator.find(bundle, new Path("webspy/lib/file.txt"), null);

url = FileLocator.toFileURL(url);

File file = URIUtil.toFile(URIUtil.toURI(url));

When your files are packed in a jar FileLocator.toFileURL will copy them to a temporary location so that you can access them using File.
