Java Webstart ClassNotFoundException WebSockets
Java Webstart ClassNotFoundException WebSockets
我正在尝试将使用多个模块的相当复杂的应用程序转换为使用 webstart 而不是 C# 等效项。 （我知道 webstart 已被弃用并且正在消失。这是一个临时解决方案）我正在使用 maven-webstart-plugin 并且似乎 运行 遇到了一个问题，我在尝试加载时遇到了 ClassNotFoundException Java-Websockets 库。问题是 websockets 包含在其中一个应用程序模块的 POM 文件中（我什至试图将其作为显式依赖项添加到主应用程序中）。它确实在 JNLP 文件中，而且它肯定在 webstart 插件生成的 lib 文件夹中，所以我很困惑为什么它找不到它。任何帮助将不胜感激。我已经尝试了我能想到的一切（主项目中的显式依赖，将对 websockets 的调用移动到主应用程序中 - 它只是将异常移动到那里）。我还启用了 Java 调试器，以便在网页 JNLP 加载时出现控制台，我确实看到它加载了 WebSocket JAR：
