This happens with empty cache. Is it possible that the build itself is generating corrupt jars then? How can I check for that?
I think this issue should be reproducible if you try to run the build inside a docker container like I do. /Torste Aikio -----Original Message----- From: Chesnay Schepler <ches...@apache.org> Sent: tiistai 8. lokakuuta 2019 12:16 To: Aikio, Torste <torste.ai...@f-secure.com>; user@flink.apache.org Subject: Re: Building Flink 1.6.4 fails with "object scala in compiler mirror not found" The only cause I know for errors such as this are corrupt jars. Try cleaning the maven cache and see if the issue persists.
