After upgrading Mac OS X to Catalina, I have been trying to execute a very basic script written in Java for Firefox in Eclipse IDE 2018.  
I've installed Gecko driver already through terminal and it's placed in `/usr/local/bin.` 

Although, I've put the path in the script,  `System.setProperty("webdriver.firefox.marionette","/usr/local/bin/geckodriver");` 

it keeps showing me error that `Webdriver driver = new firefoxDriver`  cannot be resolved. 

Any help would be appreciated !
