Maven dependencies are failing with a 501 error

Question

Recently Maven build jobs running in Jenkins are failing with the below exception saying that they couldn\'t pull dependencies from Maven Central

Answer 1

This error occured to me too. I did what Muhammad umer said above. But, it only solved error for spring-boot-dependencies and spring-boot-dependencies has child dependencies. Now, there were 21 errors. Previously, it was 2 errors. Like this:

Non-resolvable import POM: Could not transfer artifact org.springframework.cloud:spring-cloud-dependencies:pom:Hoxton.SR3 from/to central

and also https required in the error message.

I updated the maven version from 3.2.2 to 3.6.3 and java version from 8 to 11. Now, all errors of https required are gone.

To update maven version

1. Download latest maven from here: download maven
2. Unzip and move it to /opt/maven/
3. Set the path export PATH=$PATH:/opt/maven/bin
4. And, also remove old maven from PATH
