FAILED CONFIGURATION: @BeforeTest setUpDriver java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.executeAsync()V

Today we have noticed the below errors while running our test scripts.

So we have removed Android jars(android_webdriver_library-srcs.jar ,android_webdriver_library ) from our project Build path , then all the scripts started working fine.

We are still searching why this conflict happened and how to overcome this :)
