How many warnings should your JavaScript app have?

JavaScript warnings are these messages being displayed in yellow or red in your JavaScript console or terminal. They make no sense at all in general but they are a good indication of the health of your app. The points below will give you a general idea of how many warnings you should expect in your app:

• 0 warnings: the app is not working at all

• 5 warnings: app is probably starting but crashing soon after - try to find why it crashes. You'd think you could read the warnings to learn why it doesn't work, but that's not what warnings are for.

• 50 warnings: That's the soft spot - most likely everything's running smoothly

Artifactory/Customtools Functions for post install configuration

This a MVP for a global library that will configure artifactory and customtools post install as a job.

This can live as a global variable in /vars of your global pipeline. If this file was config.groovy you can call these functions as config.artifactory()

See below how to wire the global lib into casc
