Javafx並在窗口調整大小時重新定位圖像？

Question

好的，所以我試圖熟悉向對象添加偵聽器的過程，並認為我將嘗試修改我的一個應用程序，以便在調整窗格大小之后像在示例中顯示的那樣對圖像進行更新。 ..僅在此項目中，當我嘗試執行相同的操作時，出現此異常：

Exception in Application constructor
Exception in thread "main" java.lang.NoSuchMethodException: MouseEvent.MouseEventDemo.main([Ljava.lang.String;)
    at java.lang.Class.getMethod(Class.java:1773)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:119)

我使用的代碼在這里：

// Add a listener to relocate object upon pane resize
        pane.widthProperty().addListener(ov -> {
            circularText.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
            imageView2.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
        });

        pane.heightProperty().addListener(ov -> {
            circularText.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
            imageView2.relocate(pane.getWidth() / 2, pane.getHeight() / 2);
        });

如果需要整個主要代碼的一部分，可以在下面找到它：

好的，我是個白痴，顯然不是因為我添加了偵聽器，而是因為我創建了一個新項目來放置文件，並且選擇了錯誤的XD類型

同樣，我最后遇到了一個問題，因為打開了最后一個項目，因為它安裝了avast！ 並運行我的第一個快速掃描，病毒掃描程序將我的計算機鎖定了，導致我強制關機並導致.idea中的workspace.xml文件損壞了……刪除它並重新打開該項目並重新運行該程序似乎修理它
