Jlink can't put Derby into the runtime? - maven

Question

UPDATE:
Maybe it is better if I rephrase the question: How to tell Jlink to put the java.sql or derby into the runtime?
Meantime I tried it with a 'jlinkVerbose' option in the pom file and as a result I can see this after a 'mvn clean javafx:jlink':

It still gives the 'BUILD SUCCESS' result and despite it says 'java.sql file:///usr/lib/jvm/java-11-openjdk-amd64/jmods/java.sql.jmod
', the java.sql is missing from the 'Providers:' section.
END of UPDATE.
I am working on a game in Java11 + JavaFX. The building tool is Maven. The IDE is Netbeans 11.
It is a modular project.
I use this manual: https://openjfx.io/openjfx-docs/#IDE-NetBeans
The game compiles and runs smoothly, it can create/read/update the Derby DB when I start it in Netbeans via maven by 'clean javafx:run'.
When I want to create the runtime from terminal by 'mvn clean javafx:jlink' I get a 'BUILD SUCCESS' result too.
But when I try to start the launcher by 'target/adventuregame/bin/adventuregamelauncher' I get an error message:
Connection error: java.sql.SQLException: No suitable driver found for jdbc:derby:advDB;create=true

Exception running application com.mycompany.adventuregameengine.AdventureGame
I checked the target/adventuregame/lib/classlist file and it seems to me that the problem is that the jdbc / derby classes are not included. It seems to me that the Jlink can not put the jdbc into the runtime, despite that this manual
https://github.com/openjfx/javafx-maven-plugin#javafxjlink-options
writes that 'The plugin includes by default: --module-path, --add-modules and -classpath options.'
Here is my module-info.java file:
module com.mycompany.adventuregameengine {
requires javafx.controls;
requires javafx.fxml;
requires java.sql;
requires java.desktop;
// requires java.naming;
// requires java.management;
opens com.mycompany.adventuregameengine to javafx.fxml; //java.desktop, java.sql
exports com.mycompany.adventuregameengine;
}
Before I posted I've checked the similar topics here on stackoverflow, and one suggested that including java.naming and java.management could help, I tried it but it doesn't.
Here is my pom file:

I tried the 'compilerArgs' section, but it did not help.
Here is the section of my DB file what the error message refers to, but it must be OK since it runs properly via Netbeans, the problem is with the runtime.
public class DB {
final String JDBC_DRIVER = "org.apache.derby.jdbc.EmbeddedDriver";
final String URL = "jdbc:derby:advDB;create=true";
Connection conn = null;
Statement createStatement = null;
DatabaseMetaData dbmd = null;
public DB(){
try {
conn = DriverManager.getConnection(URL);
System.out.println("There is a connection.");
} catch (SQLException ex) {
System.err.println("Connection error: " + ex);
}
if (conn != null){
try {
createStatement = conn.createStatement(); //create a statement (auto)
} catch (SQLException ex) {
System.err.println("Statement error: " + ex);
}
}
//is the database empty, so the program runs first time?
try {
dbmd = conn.getMetaData();
ResultSet rs = dbmd.getTables(null, "APP", "HERO", null); //capital letter!
if(!rs.next()){
createStatement.execute("create table hero(hp INT, score INT, currentRoom INT, vanBackpack boolean)");
createStatement.execute("create table rooms(description varchar(200), eszakra INT, keletre INT, delre INT, nyugatra INT, fel INT, le INT, id INT)");
createStatement.execute("create table items(roomnumber INT, name varchar(30), description varchar(200), felveheto boolean, vizsgal varchar(200), pozX INT, pozY INT)");
}
} catch (SQLException ex) {
System.err.println("ResultSet getTables/create table error: " + ex);
}
}
If I create a simple sample project on the same way as the above manual suggests, then the runtime runs properly. It seems it can not include only the jdbc/derby.
I thank you in advance for every suggestion to solve this really annoying issue.
