如何設置JGoodies的外觀和感覺？

Question

我將jgoodies-looks-2.5.3.jar到我jgoodies-looks-2.5.3.jar並啟動它

public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    UIManager.setLookAndFeel("com.jgoodies.looks.windows.WindowsLookAndFeel");
                    ExpenseManagerGUI frame = new ExpenseManagerGUI();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

但我得到以下錯誤:(如何解決這個問題？）

Answer 1

看起來非常像你錯過了類路徑上的jgoodies-common.jar。

你可以從Maven得到這個

我強烈建議您為構建使用依賴關系管理系統，以避免將來出現這些問題

Answer 2

您缺少Maven Repository上顯示的JGoodies Common庫。 你可以在這里得到它。
