java - Could not find or load main class

I want to run a java project in terminal. When I compiled, no error occurred, but when I run the program I get the following error:

Could not find or load main class orException in thread "main"
java.lang.NoClassDefFoundError: Appium (wrong name:
com/appiumproj/test/Appium)

Please help me to solve this problem.

Answer

You need to specify the name of the class - not a filename. It needs to be the fully-qualified class name, and it needs to be on the classpath. So after compiling, you'd want something like this (just spread out on multiple lines for readability; the backslashes are line continuations - you should be able to copy and paste this straight into your shell):

java -cp  /Users/Samuel/Downloads/AppiumTest/lib/selenium-server-standalone-2.45.0.jar\
:/Users/Samuel/Downloads/AppiumTest/lib/gson-2.3.1.jar\
:/Users/Samuel/Downloads/AppiumTest/lib/java-client-2.2.0.jar\
:/Users/Samuel/Downloads/AppiumTest/src \
com.appiumproj.test.Appium
