我运行以下命令：

C:\Projects\java -cp ./dependency.jar -jar ./dist/main.jar
Exception in thread "main" java.lang.NoClassDefFoundError: MyException
Caused by: java.lang.ClassNotFoundException: MyException
    at java.net.URLClassLoader$1.run(Unknown Source)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(Unknown Source)

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: Main. Program will exit.

MyException在dependency.jar中。我也尝试用-classpath替换-cp。我做错了什么？
