How to get a path to a resource in a Java JAR file

Question

I am trying to get a path to a Resource but I have had no luck.

This works (both in IDE and with the JAR) but this way I can\'t get a path to a file, only the file

Answer 1

Maybe this method can be used for quick solution.

public class TestUtility
{ 
    public static File getInternalResource(String relativePath)
    {
        File resourceFile = null;
        URL location = TestUtility.class.getProtectionDomain().getCodeSource().getLocation();
        String codeLocation = location.toString();
        try{
            if (codeLocation.endsWith(".jar"){
                //Call from jar
                Path path = Paths.get(location.toURI()).resolve("../classes/" + relativePath).normalize();
                resourceFile = path.toFile();
            }else{
                //Call from IDE
                resourceFile = new File(TestUtility.class.getClassLoader().getResource(relativePath).getPath());
            }
        }catch(URISyntaxException ex){
            ex.printStackTrace();
        }
        return resourceFile;
    }
}
