Recently Maven build jobs running in Jenkins are failing with the below exception saying that they couldn't pull dependencies from Maven Central and should use HTTPS. I'm not sure how to change the requests from HTTP to HTTPS. Could someone guide me on this matter?
[ERROR] Unresolveable build extension:

Best Answer
The reason for the observed error is explained in Central 501 HTTPS Required
It looks like latest versions of Maven (tried with 3.6.0, 3.6.1) are already using the HTTPS URL by default.
Here are the dates when the major repositories will switch:
Your Java builds might break starting January 13th (if you haven't yet switched repo access to HTTPS)
Update: Seems like from maven 3.2.3 maven central is accessed via HTTPS See https://stackoverflow.com/a/25411658/5820670
