getting
This artifact cannot be downloaded because it is Noncompliant: Artifact does not have an associated .pom.
error for a lot of maven repositories.

https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-project/3.1.2/hadoop-project-3.1.2.pom

I understand that there is some parsing problem with POM file but it can be downloaded I guess, as SHA1 and MD5 are valid.

Let us know your thoughts.
