In your code load it as a java.util.ResourceBundle:

ResourceBundle properties = ResourceBundle.getBundle("project");

You can access the properties via the ResourceBundle API.

Put your properties file on the classpath when starting your app:

java -classpath .;test.jar;project.properties com.project.Main

Send file path as below format,

java -classpath .;test.jar; -DPROP_FILE=conf\project.properties com.project.Main

Use below code for getting property file

String propFile = System.getProperty("PROP_FILE");
Properties props = new Properties();
props.load(new FileInputStream(propFile));

Thanks.

java -classpath c:\java Client test.properties

"c:\java" is classpath - change to your java classpath

Run java -classpath .;test.jar; com.project.Main project.properties, than read this argument in your main method and load the file.

 public static void main(String[] args) {
     String fileName = args[0];
     Properties prop = new Properties();
     InputStream in = getClass().getResourceAsStream(fileName);
     prop.load(in);
 }
