我正在尝试使用 this 运行示例项目库，我收到以下错误:
Exception in thread "main" java.lang.NoClassDefFoundError:

我在 libs 和 中添加了 commons-lang-2.6.jar & commons-lang3-3.1-sources.jar>类路径
主类:
public static void main(final String[] args) throws CardException {
Main pcsc = new Main();
CardTerminal ct = pcsc.selectCardTerminal();
Card c = null;
if (ct != null) {
c = pcsc.establishConnection(ct);
CardChannel channel = c.getBasicChannel();
PcscProvider provider = new PcscProvider(channel);
EmvParser parser = new EmvParser(provider, false);
parser.readEmvCard();
c.disconnect(false);
}
}

最佳答案
I have added commons-lang-2.6.jar & commons-lang3-3.1-sources.jar...
这是你的问题:commons-lang-2.6.jar 不包含 org.apache.commons.lang3 包，因为它是版本 3 的一部分，并且commons-lang3-3.1-sources.jar 包含源代码，而不是字节码。
您需要改为包含 commons-lang3-3.1.jar。
