Goal prepare-package hangs in RC7

Description of the bug

The build-process hangs at the goal prepare-package. If we kill node three times it continues until Running npm install then one needs to kill node again. Aftrer that it works flawlessly. Please see the attached log killingnode.txt. Other people have the same problem

We do have a proxy in our company, but it is configured correctly in Java/Maven and we didn’t have any problems until 2019-08-05. The networking department assured me that there were no changes to proxy/firewall/etc.

Just tell me if I can be of any assistence.

Minimal reproducible example

• Starter project
• downloaded today
• version14
• CDI and Java EE

Expected behavior

The project build after typing mvn package

Actual behavior

The build hangs at prepare-package.

Versions

• Vaadin / Flow version 14
• Java version javac 12.0.2
• OS version Windows 10
• Node 10.16.1 (Node 10.16.0 doesn’t wor either.)
• Browser version (if applicable) N/A

Stefan Apelt found the solution.

NPM makes a version check over the internet on every invocation and ignores it’s proxy setting. One can disabale this check with the environment-variable NO_UPDATE_NOTIFIER=1.

Would it be possible, to include this setting in the maven plug-in to reduce build-time and support people behind corporate proxies?

That’s a good find. We really don’t need npm to do anything extra for npm -v, especially not a call out to check for updates.
