Selenium - NoClassDefFoundError: org/openqa/selenium/NoAlertPresentException

Question

NoClassDefFoundError: org/openqa/selenium/NoAlertPresentException: I'm executing a piece of code which is giving this error. This is written in Junit on eclipse using Selenium. It works fine through eclipse but I need to share it with team on a shared repository. It has to work through command line but its failing with this error. Z:\TripPlanner\lib>java -cp .;junit-4.12.jar;hamcrest-core-1.3.jar;Z:\TripPlanner\lib* org.junit.runner.JUnitCore "com.example.tests.TripPlannerJUnit" JUnit version 4.12 Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/NoAlertPresentException at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:398) at org.junit.internal.Classes.getClass(Classes.java:16) at org.junit.runner.JUnitCommandLineParseResult.parseParameters(JUnitCommandLineParseResult.java:100)at org.junit.runner.JUnitCommandLineParseResult.parseArgs(JUnitCommandLineParseResult.java:50 at org.junit.runner.JUnitCommandLineParseResult.parse(JUnitCommandLineParseResult.java:44)at org.junit.runner.JUnitCore.runMain(JUnitCore.java:72) at org.junit.runner.JUnitCore.main(JUnitCore.java:36) Caused by: java.lang.ClassNotFoundException: org.openqa.selenium.NoAlertPresentException

If it compiles and runs in Eclipse, you will have additional jar files added to your project. It will look similar to this:

You will need all those dependencies added to your classpath. It is possible to use wildcards like it is described in Including all the jars in a directory within the Java classpath. But you will need all the libraries of your Eclipse Java Build Path in your classpath if you are running your code standalone.
