java - 无法在 OS X 上与 JavaCV 中的 Maven 一起初始化类 org.bytedeco.javacpp.avutil

我已将以下依赖项添加到我的 maven 项目中。

    </dependency>

然后运行提到的代码here .我使用 FFmpegFrameGrabber 而不是 OpenCVFrameGra

我收到以下错误。

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacpp.avutil

有什么想法吗？我在使用 JDK 1.7 的 OS X Yosemite 上。

正如 Samuel Audet 提到的，这个问题在使用“platform.dependencies”属性后得到了解决。例如:

 $ mvn package exec:java -Dplatform.dependencies -Dexec.mainClass=Demo
