rmetzger opened a new pull request #11582: [FLINK-16411][AZP] Cache maven artifacts for tests as well URL: https://github.com/apache/flink/pull/11582 ## What is the purpose of the change Our CI tests are failing very frequently due to connectivity issues. Most likely, the servers have some network problems. As a temporary mitigation, I'm enabling the maven caches for all jobs. This will add ~10 minutes of build time for each task, reducing our overall throughput. But I want our builds to be greener :) In the meantime, I will try to understand the root cause of this. ## Brief change log - relax the condition for enabling the cache task. ## Verifying this change In 6 runs, there was only one failure, and that was caused by an unstable e2e test: <img width="965" alt="Screenshot 2020-03-31 16 39 07" src="https://user-images.githubusercontent.com/89049/78039241-2904d200-736e-11ea-94b3-4caef13590e5.png";>
