英文:
how to call javaBridge Main from java application
问题
我有关于这个问题的疑问
这是我的主类
这是我的代码
导入dxtr.mtapi.mt4.data.QuoteClient;
导入php.java.bridge.JavaBridge;
public class Main {
public static void main(String[] args) throws IOException {
QuoteClient qc = new QuoteClient(12342, "xasd", "localhost", 9900);
JavaBridge.main(args);
}
}
运行时出现错误
线程 "main" 中的异常 "java.lang.NoClassDefFoundError: php/java/bridge/JavaBridge"
at dxtr.main.Main.main(Main.java:12)

JavaBridge 是不同的 jar 包。所以我从本地添加了它，就像下面这个 pom 里面的一样。为什么我的代码在这里报错？

我尝试使用这个示例中的 pom，来更新我的 pom。但我仍然不能在我的代码中运行 JavaBridge。如何从我的代码中运行 java bridge.jar？
这是我添加到代码中的图片
[![这是 JavaBridge 截图][1]][1]
那么如何解决这个问题？我是否需要添加代码或者其他什么？

我还尝试过这个命令
java -cp JavaBridge.jar:build Dxtr.main.Main
但是我得到了错误：
错误: 找不到或无法加载主类 Dxtr.main.Main
那么在尝试运行 JavaBridge.main 时如何解决这个问题？
