问题
我正在尝试在NetBeans（适用于Mac）上在标签上设置图像图标。
我在项目文件夹中导入图像后设置了图像：
screenshot of selected image
当我尝试运行项目时，出现以下错误：
Exception in thread "main" java.lang.NullPointerException
at java.desktop/javax.swing.ImageIcon.<init>(ImageIcon.java:217)
at Laboratorio.Login.initComponents(Login.java:52)
at Laboratorio.Login.<init>(Login.java:17)
at Laboratorio.Main.main(Main.java:26)
Login.java:52:
labelLogo.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Laboratorio/Immagini/logo_550.png")));
图像的路径是：
/Users/salvatore/NetBeansProjects/Laboratorio/src/main/java/Laboratorio/Immagini/logo_550.png
有人能帮我吗？谢谢！

我解决了。
我之前使用Java和Gradle（从未使用过）... 我一直使用Java和Ant。现在它使用相同的代码正常工作。

I was using Java with Gradle (never used)... I always used Java with Ant. Now it works correctly with the same code.
