Answer 1

You need to use Java 11 (or above) with WebDriverManager 5.4.0 (or above).

UPDATE: To provide a solution to those that cannot bump to Java 11, I released WebDriverManager 5.5.3, compiled with Java 8.

In any case, my personal opinion is that Java 8 is already an ancient version, and I recommend using at least Java 11+ as soon as possible.

Answer 2

The Error means that the dependency class may not compiled/downloaded correctly. To fix this issue you need to re-compile the maven file

if using IntelliJ IDEA, go to maven and run "clean" command and run "install" command this will clean and re-download the dependency class files correctly. if required adjusts the TestNG maven dependency version to a stable version
