It looks like TeamCity is having problems since a few days ago - builds of master and PRs are flaky. Here's the link to recent builds of master: https://teamcity.jetbrains.com/viewType.html?buildTypeId=OpenSourceProjects_Druid_Inspections&tab=buildTypeHistoryList&branch_OpenSourceProjects_Druid=__all_branches__
It looks like the Windows agents generally work fine and the Ubuntu agents are flaky. I can't see any recent commits that seem likely to have caused this so am assuming something is going wrong on the TeamCity server side. I looked at the logs of a few successful and a few failed builds and noticed the failed ones have a lot of these messages, but the successful ones didn't: [Step 1/1] [ 43336] WARN - ution.rmi.RemoteProcessSupport - [RMI TCP Connection(3)-127.0.0.1] WARN org.eclipse.aether.internal.impl.DefaultUpdateCheckManager - Failed to create parent directories for tracking file /home/teamcity/.m2/repository/org/apache/apache/21/apache-21.pom.lastUpdated I'm not sure what that might indicate or what to do about it. Maybe we need to… clear… some caches? Anyone have any ideas?
