Question

我在java中完成了一个项目，即使用javaCV库进行运动检测。当我从netbeans调试代码时，它正常工作。它会检测动作并发出警报，发送邮件等。但是当我清理并构建代码时，获取的.jar文件没有加载网络摄像头。当我打开.jar文件时，它会显示一个空白画布。我可以提供的另一个信息是，当我清洁＆amp; bulid，o / p显示了一些警告，例如弃用的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

运行它

如果从dist目录运行它，它将包含项目所需的库。我怀疑你是在试图在没有关联库的情况下运行项目。

成功清理和构建后，JavaCV无法运行
