我试图混淆与“com.github.sarxos”proguard的，Maven的插件外部的lib com.github.sarxos混淆
我导入外部LIB“网络摄像头捕捉”一个simlpe Java应用程序类
import com.github.sarxos.webcam.Webcam;
而且somwhere在应用程序中调用一个方法
Webcam webcam = Webcam.getDefault();
没有混淆的一切运作良好，但混淆后的jar我有运行时错误：
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: com/github/sarxos/webcam/Webcamat
mdr.apmik.a.run(Unknown Source)

这里的proguard-maven-plugin来自我的pom.xml。我设置了一个跳过com.github.sarxos.webcam类混淆的选项，但没有成功。

我的问题是 - 有可能使用ProGuard和像这样的图书馆吗？ 如果是，如何为此配置Proguard？
