System.setProperty("webdriver.chrome.driver", "C:\\chromedriver\\chromedriver.exe");
def browser = new Browser(driver: new ChromeDriver())

Any idea on this how to resolve it ???

Answer 1

To use Geb/Chrome you will have to configure it on Mac, download the Chrome Web Driver from http://chromedriver.storage.googleapis.com/index.html and move the chromedriver to usr/bin folder. Restart terminal and run your Geb test with Chrome driver and it should work.

Answer 2

As stated here,The followings can be the reason for your Exception.
Class is not available in Java Classpath.
You might be running your program using jar command and class was not defined in manifest file's ClassPath attribute.
Any start-up script is overriding Classpath environment variable.
Because NoClassDefFoundError is a sub class of java.lang.LinkageError it can also come if one of it dependency like native library may not available.
Check for java.lang.ExceptionInInitializerError in your log file. NoClassDefFoundError due to failure of static initialization is quite common.
If you are working in J2EE environment than visibility of Class among multiple Classloaders can also cause java.lang.NoClassDefFoundError, see examples and scenario section for detailed discussion.
