成功清理和构建后 JavaCV 无法运行

Question

我用 java 完成了一个项目，即使用 javaCV 库的运动检测软件。当我从 netbeans 调试代码时它工作正常。它检测运动并发出警报、发送邮件等。但是当我清理和构建代码时，获得的 .jar 文件没有加载网络摄像头。当我打开那个 .jar 文件时，它显示一个空白 Canvas 。我可以提供的另一个信息是，当我清理和构建时，o/p 会显示一些警告，例如已弃用的 API。

Answer 1

输出表明您应该从命令行 java -jar "C:\Users\Anooj\Documents\NetBeansProjects\projectlogin\dist\projectlogin.jar

如果您从 dist 目录运行它，它将包含项目所需的库。我怀疑您正在尝试在没有关联库的情况下运行该项目。
