在 Netbeans 中，我使用 Jlabels 在 JFrame 中显示图像和文本。 Jlabels 在 IDE 中正确显示，但是当我运行或构建项目时，一些 Jlabels 没有显示(在前几个标签之后添加的标签)。要解决此问题，我必须重新开始并一次添加所有图像。这很糟糕，因为我从 4 张变成了 8 张，现在我需要再添加 20 张图像。我真的不想一切从头再来。

最佳答案
尝试运行清理并构建(运行 > 清理并构建主项目)。 NetBeans ant 脚本不会跟踪您的类文件依赖于资源文件这一事实，因此在编译类时，它会被复制到 build/classes(并从那里复制到 jar)，但资源不是。
关于java - 构建项目时不显示 Netbeans JLabel 图标/文本，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/2739147/
