ClassNotFoundException: javafx.fxml

Question

I have this problem, when i Edit run configuration.

Error: Could not find or load main class books Caused by: java.lang.ClassNotFoundException: books

This is the main class where i compile the project:

package sample;
        import javafx.application.Application;
        import javafx.fxml.FXMLLoader;
        import javafx.scene.Parent;
        import javafx.scene.Scene;
        import javafx.stage.Stage;
        
        import java.io.IOException;
        
        public class books extends Application {
        @Override
            public void start(Stage stage)throws IOException {
            FXMLLoader fxmlLoader = new FXMLLoader(books.class.getResource("sample/book.fxml"));
        Scene scene = new Scene(fxmlLoader.load());
        stage.setTitle("Library");
        stage.setScene(scene);
        stage.show();
        
        }
            public static void main (String[] args ){launch(args);}
        }
        

Its my fxml Controller class:

 package sample;
        
        import Dialog.AlertDialog;
        import javafx.event.ActionEvent;
        import javafx.fxml.FXML;
        import javafx.fxml.Initializable;
        import javafx.scene.control.Button;
        import javafx.scene.control.TextField;
        
        import java.net.URL;
        import java.sql.Connection;
        import java.sql.Date;
        import java.sql.PreparedStatement;
        import java.sql.SQLException;
        import java.util.ConcurrentModificationException;
        import java.util.ResourceBundle;
        
        public class FXMLDocumentController implements Initializable {
        
            @FXML
            private Button butt_add;
        
            @FXML
            private TextField txt_codeclass;
        
            @FXML
            private TextField txt_codepublish;
        
            @FXML
            private TextField txt_databook;
        
            @FXML
            private TextField txt_namebook;
        
            private Connection conn = null;
            private PreparedStatement pat = null;
        
            @FXML
            void handleAddbook(ActionEvent event) throws SQLException {
                String sql  = "Insert into books(bookname,idPublish,Datebook,idclass) 
               Values(?,?,?,?)";
                String bookname = txt_namebook.getText();
                String publish = txt_codepublish.getText();
                Date date = Date.valueOf(txt_databook.getText());
                String IDclass = txt_codeclass.getText();
                try {
                    pat = conn.prepareStatement(sql);
                    pat.setString(1,bookname);
                    pat.setString(2,publish);
                    pat.setDate(3,date);
                    pat.setString(4,IDclass);
        
                    int i = pat.executeUpdate();
        if (i==1)
            //System.out.println("Data Inserted Successfully");
            AlertDialog.display("info","Data Insert Successfuly");
                } catch (SQLException e) {
                    e.printStackTrace();
                }
        
                finally {
                    pat.close();
                }
            }
        @Override
            public void initialize (URL url, ResourceBundle rb){
        conn = SQLConnect.peartConnection();
        }
        }

This is connection with sql server studio, And it was worked.

package sample;
        
        import java.sql.Connection;
        import java.sql.DriverManager;
        import java.sql.ResultSet;
        import java.sql.SQLException;
        import java.sql.Statement;
        import java.util.logging.Logger;
        
        public class SQLConnect {
            public static Connection peartConnection() {
                Connection conn = null;
                try {
                    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                    String url = "jdbc:sqlserver://localhost:1433;databaseName=Library;username=adminn;password=bahytn001";
                    conn = DriverManager.getConnection(url);
                } catch (ClassNotFoundException | SQLException e) {
                   e.printStackTrace();
                }
                return conn;
            }
        }
        

I created special class module-info.java and write javafx libraries:

module application {
              requires javafx.controls;
                requires javafx.graphics;
                requires javafx.fxml;
                requires javafx.base;
                requires java.sql;
        
                opens sample;
        }

Please help me don't give me any links please. I will be very grateful. I work with Intellij 2021.2.2 JDK 14, JDBC 11
