Answer 1

The error suggests that there is a error in parsing the Javascript of webdriver-manager. webdriver-manager was updated to ES6 (and that's why we need Node 6+) and threw the ... errors in the past for older version of node.
Based on that I would say that Eclipse is running on an older version. After searching the webdriver-manager git I found this issue. I think it matches your problem and also gives you the steps to check which version of node Eclipse is using.
Hope it helps
