NPM version check exceptions at start of Spring Boot starter

[alump]

Setup:

• Preview Eclipse plugin (for 14 support)
• Eclipse 2019-06 (4.12.0)
• MacOS 10.14.5
• Amazon Corretto 11

Steps:

1. New Vaadin project, use Spring Boot starter
2. Run mvn spring-boot:run

Expected outcome:
Application starts without exceptions

Actual outcome:
Something goes wrong at npm version check. Application starts, but I think output should be cleaned up if it's not fatal. Gives bad first impression.

I haven't seen this issue on Intellij IDEA
