无法在终端中运行mvn test

Question

I am doing a hello world for Selenium Webdriver using Intellij and Maven and I am able to get the project to run the test successfully in Intellij.

But when I go to the project root directory in terminal it fails. I tried looking in past questions and cannot find a solution that fixes this issue.

My Terminal:

Any help would be great.

Answer 1

The JDK set in IntelliJ probably differs from your JAVA_HOME environment variable. Check mvn -version to see wich java version it is using and compare it to the one in your project settings in IntelliJ

Answer 2

The underlying issue is

Caused by: java.lang.UnsupportedClassVersionError: org/openqa/selenium/WebDriver : Unsupported major.minor version 51.0

This means you're trying to use a JAR built with a class version of 51, ie, it was built for Java 7.

It seems that the java you're using (usually defined by $JAVA_HOME ) is an earlier version. Just make sure to install Java 7 or newer and point $JAVA_HOME to it, and you should be OK.
