This question is related to NoClassDefFoundError in Java: com/google/common/base/Function
I get the exact same error, but I didn't manually add jars, I used maven instead.
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>2.48.2</version>
</dependency>
in the old post, someone used maven suggested adding another dependence of guava 15.0. I tried, but not work. Is there a way to solve it only using maven without manually add selenium-server-standalone-version.jar?
