Exception using Selenium with Firefox on MacOS

[Ida Blom]

Hi Everyone

I'm having some trouble getting Firefox to work in Selenium on my Mac.  Any ideas or suggestions would be really appreciated.

Selenium version: 3.7.1 or 3.9.1
Geckodriver: 0.19.1
Java: 8

As soon as I launch I get this:

java.lang.NoSuchMethodError: com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder;

My dependencies.gradle file has
ibraries.googleGson = 'com.google.code.gson:gson:2.2.2@jar'

I set my driver like this:

System.getProperties().setProperty("webdriver.gecko.driver",
        "/Applications/geckodriver");

I've also tried this:

System.getProperties().setProperty("webdriver.firefox.marionette",
        "/Applications/geckodriver");
DesiredCapabilities capabilities= DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);

but I get the same exception - is this just a matter of upgrading the gson jar?
Thanks

Yes. You need to upgrade your gson version.

 

Selenium by default would bring in the version that it needs viz., gson 2.8.2

 

See here https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java/3.9.1

 

So you might as well just remove the explicit dependency on gson and try again.

 

Thanks & Regards
