incompatibility with Gradle 6.0-RC1: node.js download fails

[xzel23]

This is more or less the same as #292 . However, I am not behind a proxy, and the problem only shows when using the plugin on Gradle 6.0-RC1. If I call an older Gradle version like 5.6.1, the build is successful. FWIW gradle 6.0 final is expected to be released next week.

Just saw that this is the same as #351. Don't know how I could miss that. Sorry.
