I'm trying to connect to a db file in my project but having some troubles. I'm using JDK 14 with ojdbc11 however I am still getting this when trying to connect:

java.lang.UnsupportedClassVersionError: 
oracle/jdbc/driver/OracleDriver has been compiled by a more recent 
version of the Java Runtime (class file version 54.0), this version 
of the Java Runtime only recognizes class file versions up to 52.0

Looking off of this post, I should be able to recognize class files up to 58. My code is below for reference in case I've done something wrong there but it seems like my JRE is out of date despite it being version 14. Maybe I am using the wrong ojdbc file?

java -version
java version "14.0.2" 2020-07-14
Java(TM) SE Runtime Environment (build 14.0.2+12-46)
Java HotSpot(TM) 64-Bit Server VM (build 14.0.2+12-46, mixed mode, 
sharing)

package commands;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Connect {  
	private static String fileName = "builderData.db";

public static String connect() { 
	String status = "";
	Connection conn = null;  
	try {  
		String url = "jdbc:sqlite:" + System.getProperty("user.dir") + "/src/main/java/resources/" + fileName;  
		Class.forName("oracle.jdbc.driver.OracleDriver"); //<-- cause of error
		conn = DriverManager.getConnection(url);  
         
		status = "Database connection established.";  
         
	} catch (SQLException e) {  
		status = e.getMessage(); 
	} catch (ClassNotFoundException e) {
		status = "Class Not Found: " + e.getMessage();
	} finally {  
		try {  
			if (conn != null) {  
				conn.close();  
			}  
		} catch (SQLException ex) {  
			status = ex.getMessage();  
		}  
	} 
	return status;
}  
}
