Unable to configure system property -Dwebdriver.chrome.driver (using version 2.20)

[poddarsumit]

Command run:
PS C:\Selenium2> java -Dwebdriver.chrome.driver="C:\Selenium2\chromedriver.exe" -jar .\selenium-server-standalone-2.20.0.jar -role hub

Exception in thread "main" java.lang.NoClassDefFoundError: /chrome/driver=C:\Selenium2\chromedriver/exe
Caused by: java.lang.ClassNotFoundException: .chrome.driver=C:\Selenium2\chromedriver.exe

Could not find the main class: .chrome.driver=C:\Selenium2\chromedriver.exe.  Program will exit.

Have JAVA runtime java version "1.6.0_26" installed.

Can you let me know what I am doing wrong. 

I have downloaded the chrome driver from the selenium website but not able to install the system property

Take a look here http://rationaleemotions.wordpress.com/2012/01/23/setting-up-grid2-and-working-with-it/

and see if the batch file that I talk about there helps you get past this problem.

Thanks & Regards

All you need is to have your PATH environment variable set to point to
the directory where chromedriver.exe lives. I don't use a -D option
to set any property and the fact that it seems to screw up the name
when it reports the error suggests that it doesn't work right the way
you are doing it, either.

Notice it says: C:\Selenium2\chromedriver/exe

Why it changes the .exe into /exe is beyond me.

Chromedriver installation documentation blows.

On Mac or any other OS

/end transmission

[Simon Stewart]

If you feel like that, we'd really appreciate some improved docs. Is
there any information you need in order to submit these?

Otto,

Before we all nod our heads to that "transmission" do you mind sharing with us, as to what didnt make sense to you with respect to the documentation for ChromeDriver ?

How about you helping us understand what all have you done so far, before you gave up on it ?

As Simon said, if you feel the documentation is not good enough or you can always contribute to enhancing and making it better, since Selenium is an open source project and the core selenium development team would be very happy to receive patches.

Thanks & Regards

Was there ever a resolution to this issue?
I'm in the process of provisioning an Windows Selenium node with ansible and have now run into this problem.

[Krishnan Mahadevan]

Anthony,

To begin with this never was a problem. It perhaps is being caused because of the improper way of passing in the JVM arguments. Can you please call out your exact problem ? If you have the chromedriver binary available in the PATH variable, that itself should suffice and you don't need to pass in its location via the JVM argument.

Thanks & Regards

I disagree. It's a violation of Postal's Law and creates an affordance mismatch

When  I run this command in Powershell

java -Xmx200m -Dwebdriver.chrome.driver="C:\selenium\chromedriver.exe" -Dwebdriver.ie.driver="C:\selenium\IEDriverServer.exe" -jar C:\selenium\selenium-server-standalone.jar -role node -nodeConfig C:\selenium\nodeconfig.json

I get the error

The command is what Googling tells me is A way for specifying the location of the driver binary.

Anthony

Until now I had no idea as to what was a Postel's law :) So thanks for introducing me to it...

Coming back to your problem, like I said before, its not Seleniuim that is at fault here :)

Its powershell that's wrecking havoc here.

Take a look at this StackOverflow link : http://stackoverflow.com/questions/6347985/cannot-run-maven-using-mvn-d-argument-within-microsoft-powershell

The fix is basically to wrap up your JVM arguments which specify the location of chromedriver and IEDriverServer within single quotes and that should do it.

Hi Anthony,

I don't have a Windows computer handy at the moment. So I cannot test this but did you try escaping the \ character?

If it is something being used on the command line by MS-DOS Prompt, e,g, C:\selenium\selenium-server-standalone.jar, then Windows is okay with the use of backslash. However, if it is being passed to the JVM the use of backslash needs to be escaped, e.g. "C:\\selenium\\chromedriver.exe" or you can use the file separator normally recognized by the JVM, e.g. "C:/selenium/chromedriver.exe"
