Hi Cory!

Hmmm, curios... I just double check the code, there are no more references to a Scala-versioned "flink-core" and "flink-annotations" project in the code base.

The projects you use with Scala version suffix look good, actually. Just to be safe, can you check that the "flink-java" dependency is without suffix?

One other thing I can imagine is a mixed up dependency cache. Can you try to refresh all snapshot dependencies (maybe clear "~/.sbt/staging/").

It is high-time for a 1.0 release, so you need not work on the SNAPSHOT versions any more. That should really solve this version conflict pain.

If we are fast tomorrow, there may be a nice surprise coming up in the next days...

Greetings,

Stephan

Hmm. We don't explicitly include "flink-annotations" and we do not append the Scala suffix for "flink-core":

`"org.apache.flink" % "flink-core" % "1.0-SNAPSHOT"`

Here are the packages we currently include with a Scala suffix:

flink-scala

flink-clients

flink-streaming-scala

flink-connector-kafka-0.8

flink-test-utils

flink-streaming-contrib

If there is any documentation you can point to regarding when to include the Scala suffix on Flink packages, let me know.

Hi Cory!

"flink-core" and "flink-annotations" should not have Scala suffixes, because they do not depend on Scala.

So far, we mark the Scala independent projects without suffixes. Is that very confusing, or does that interfere with build tools?

Greetings,

Stephan
