zachgk commented on issue #15605: Scala GPU Build examples CI failure URL: https://github.com/apache/incubator-mxnet/issues/15605#issuecomment-514334757 The problem doesn't lie on Maven so I don't think there is anything Maven can do to address it directly. Usually we would add some amount of retries for downloading. I just looked and there doesn't seem to be a way to make Maven retry downloading. I would be hesitant to retry the entire Maven test because this doesn't seem to be a frequent problem and it would immediately multiply the cost of the Scala tests. We could try to do something to improve the error message. Currently, it is: > Failed to execute goal on project mxnet-examples: Could not resolve dependencies for project org.apache.mxnet:mxnet-examples:jar:INTERNAL: Could not transfer artifact nu.pattern:opencv:jar:2.4.9-7 from/to central (https://repo.maven.apache.org/maven2): GET request of: nu/pattern/opencv/2.4.9-7/opencv-2.4.9-7.jar from central failed: Connection reset -> [Help 1] I feel like this error message is clear enough that it was some kind of networking problem. Are you thinking some kind of CI specific error messaging?
