Description

Builds with Java bindings enabled fail on ubuntu-14.04 (this e.g., includes reviewbot builds) with the following error

22:28:09 Building mesos-1.10.0.jar ...
22:28:09 /bin/sed -i.bak 's/mesos\.mesos_pb2/mesos_pb2/' python/interface/src/mesos/v1/interface/scheduler_pb2.py && rm python/interface/src/mesos/v1/interface/scheduler_pb2.py.bak

The error seems to be due to the maven version we use in ubuntu-14.04 CI images not using HTTPS by default which seems required since 2020-01-15

Question

As of January 15, 2020 I am receiving the following responses upon making requests to The Central Repository:

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

501 HTTPS Required.
Use https://repo1.maven.org/maven2/
More information at https://links.sonatype.com/central/501-https-required

Requests to http://repo.maven.apache.org/maven2/ return a 501 HTTPS Required status and a body:

501 HTTPS Required.
Use https://repo.maven.apache.org/maven2/
More information at https://links.sonatype.com/central/501-https-required

How do I satisfy this requirement so that I can regain access to Central?
Answer

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.
