Hi Timo, Regarding the dependency issue, looking at flink-table's pom.xml, I believe the issue is the dependency on flink-streaming-scala, which then transitively depends on almost all of the core flink modules. If it had not been for the aforementioned JIRA issue about OOM errors, I probably would've just declared my dependency in SBT like this and been done with it:
"org.apache.flink" %% "flink-table" % "1.2.0" exclude("org.apache.flink", "flink-streaming-scala"), As for the missing Janino artifacts, I agree it is strange as the dependency is declared - and the JAR contained the calcite dependencies. I basically followed the standard "build from source" steps (as documented here https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/building.html), and copied the flink-table JAR that was in the target/ directory. If there is trouble reproducing, I'm happy to provide a more detailed set-up. Thanks!
