这是否看起来像你的问题吗？ https://github.com/sarxos/webcam-capture/issues/114 – msandiford 2015-02-08 23:24:14

这可能是关于相关性的问题。它说它找不到org.bridj.cpp.CPPObject类。

尝试创建一个新的Maven项目，并在您pom.xml以下依赖性：

<dependency> 
    <groupId>com.github.sarxos</groupId> 
    <artifactId>webcam-capture</artifactId> 
    <version>0.3.10</version> 
</dependency>
