Couldnt find ab-cd config file for this filepath:config.properties. <phase>package</phase><goals> <goal>shade</goal> </goals> - maven

Question

mvn package - ruunable jar file is unable to locate this properties file. In Eclipse my application runs fine but after i create mvn package. runnable jar file is giving me me null pointer. I used 7zip to view the create runnable jar file i see config.properties is correctly added in jar but my ruunable application jar is not picking it up.
I am getting null pointer here..... Its coming from JAR file which i cant edit.
ClassLoader classLoader = super.getClass().getClassLoader();
File file = new File(classLoader.getResource(fileName).getFile());
if (file.exists()) {
reader = new FileReader(file);
instance.properties.load(reader);
} else {
System.out
.println("Couldnt find ab-cd config file for this filepath:"
+ fileName);
