Java jTable MouseListener not working

Question

I have problem with my mouselistener on jTable. This is my code:

 final JTable jTable1 = new JTable(tablemodel);
        JScrollPane scroll = new JScrollPane(jTable1);

        jTable1.addMouseListener(new MouseAdapter(){
            public void mouseClicked(Event e){
                System.out.println("clicekd on table");
            }
        });

But this code not working, When I click on the cell data from the sysout does not show up. Eclipse tells me: The method mouseClicked(Event) from the type new MouseAdapter(){} is never used locally

Edit: This is my function, everything works well except jTable.addMouseListener

public void categoryShow() {
        // TODO Auto-generated method stub
        appListener.getCategory();
        List<Category> people = model.getPeople();

        DefaultTableModel tablemodel;

        tablemodel = new DefaultTableModel();
        final JTable jTable1 = new JTable(tablemodel);
        JScrollPane scroll = new JScrollPane(jTable1);

        jTable1.addMouseListener(new MouseAdapter(){
            @Override
            public void mouseClicked(MouseEvent e){
                System.out.println("clicekd on table");
            }
        });

        tablemodel.addColumn("ID");
        tablemodel.addColumn("Nazwa");

        for (Category person : people) {

            tablemodel.addRow(new Object[]{person.getId(),person.getName()});

        }
        JPanel controls = new JPanel(new BorderLayout(5,5));
        JPanel buttons = new JPanel(new GridLayout(0,1,4,4));

        JButton deletebutton  = new JButton("Usuń");
        JButton newrow = new JButton("Dodaj");

        }); 
        jTable1.getModel().addTableModelListener(new TableModelListener(){
            public void tableChanged(TableModelEvent e){
                // TODO Auto-generated method stub
                    if(jTable1.getCellEditor() != null){
                    int col = jTable1.getSelectedColumn();

Answer 1

The signature of

public void mouseClicked(Event e){

should be

@Override
public void mouseClicked(MouseEvent e) {

Answer 2

I had to delete the files within the Project workspace:

• .project
• .classpath

And the folder:

• .settings

Then I create new projekt with jre8 and import files. My JRE System Library in project = JavaSE-1.7 and everything works well. I must delete unnecessary @Override in my function. My MouseListener function looks like @Reimeus told.
