Netbeans JLabel圖標/文本在項目建立時不顯示

在Netbeans中，我使用Jlabels在JFrame中顯示圖像和文本。 Jlabels在IDE中正確顯示，但是當我運行或構建項目時，某些Jlabel不顯示（稍後添加的標籤）。要解決這個問題，我必須重新開始，並一次添加圖像。這吸吮，因爲我從4到8，現在我需要添加20多個圖像。我真的不想重新開始。Netbeans JLabel圖標/文本在項目建立時不顯示

嗯...我有一個非常類似的問題几几天前一些菜單項沒有顯示，我解決了同樣的問題。我想知道他們是如何相關的？ – 2010-04-29 16:49:06

嘗試運行一個乾淨的構建（運行>清理和生成主項目）。 NetBeans Ant腳本不會跟蹤類文件對資源文件有依賴性的事實，因此，當編譯該類時，它將被複制到build/classes（並從那裏到jar），但資源不是。

謝謝你的工作。我以爲我嘗試過之前（我想我只打生成按鈕）。 – Theopile 2010-04-29 17:10:22

這與我在菜單中遇到的問題相同。 IDE生成的菜單也使用存儲在資源文件中的文本。謝謝。 – 2010-04-30 13:04:55

原因：Invalid Image path ... 請使用相對於您的項目文件夾的路徑。（IDE可以緩存圖像）

除了指定完整路徑：

Ex : c:/User/Project/Myapp/src/apple.png

使用相對路徑paticular類文件：

Ex : src/apple.png
