I appreciate all your assistance on this. The Javalin uber pom contains a property that contains: <webdrivermanager.version>6.3.2</webdrivermanager.version>. Doing a mvn dependency:tree shows it IS using 6.3.2. Now, here is the capper: When I run in IntelliJ using the bundled Maven, the dependency doesn't download. But, I tried it from the terminal and it DID download. The Maven running from terminal is up to date. The version bundled with IntelliJ is down 2 point releases (3.9.11 vs 3.9.9). Anyway, I'm up and running now. Thanks!
