Requests to http://repo1.maven.org/maven2/ return a 501 HTTPS Required status and a body [duplicate]

Effective January 15, 2020, The Central Repository no longer supports insecure communication over plain HTTP and requires that all requests to the repository are encrypted over HTTPS.

If you’re receiving this error, then you need to replace all URL references to Maven Central with their canonical HTTPS counterparts:

Replace http://repo1.maven.org/maven2/ with https://repo1.maven.org/maven2/

Replace http://repo.maven.apache.org/maven2/ with https://repo.maven.apache.org/maven2/

If for any reason your environment cannot support HTTPS, you have the option of using our dedicated insecure endpoint at http://insecure.repo1.maven.org/maven2/

For further context around the move to HTTPS, please see https://blog.sonatype.com/central-repository-moving-to-https.
