Java OkHttp NetBeans NoClassDefFoundError
我有一个Android应用程序，使用OkHttp进行网络速度测试。现在我需要使用NetBeans 8.2为桌面创建另一个客户端，但我无法使OkHttp工作。我包括了库okhttp-3.11.0和okio-2.0.0，但得到了java.lang.NoClassDefFoundError 我的代码是：Java OkHttp NetBeans NoClassDefFoundError,java,noclassdeffounderror,netbeans-8,okhttp3,Java,Noclassdeffounderror,Netbeans 8,Okhttp3,我有一个Android应用程序，使用OkHttp进行网络速度测试。现在我需要使用NetBeans 8.2为桌面创建另一个客户端，但我无法使OkHttp工作。我包括了库okhttp-3.11.0和okio-2.0.0，但得到了java.lang.NoClassDefFoundError 我的代码是： public class TestCheckNetwork { private final JFrame frame; private final OkHttpClient client; lon

我只找到了Maven或Android的解决方案。我的错误在哪里？没有OkHttp我怎么能犯？感谢您尝试将kotlin stdlib和stdlib公共依赖项添加到您的构建中
