RE: Can't build Flink for Scala 2.12
In the meantime, I had a look at the Travis YAML file for examples how there the compilation for 2.12 is happening. It appears that 1) there might be a typo, because the build profile is 2.112 instead of 2.12 (see https://github.com/apache/flink/blob/master/.travis.yml#L143) and there's also not a build profile for only 2.12, it always includes Hadoop
Thanks, Martijn

Subject: Can't build Flink for Scala 2.12
Hi all,
I'm trying to build Flink (from current master branch) for Scala 2.12, using:
mvn clean install -Pscala-2.12 -Dscala-2.12 -DskipTests
It fails for me on the with this error:
[ERROR] /home/pa35uq/Workspace/flink/flink-table/flink-table-planner-blink/src/main/scala/org/apache/flink/table/plan/metadata/FlinkRelMetadataQuery.scala:52: error: value EMPTY in class RelMetadataQuery cannot be accessed in object org.apache.calcite.rel.metadata.RelMetadataQuery
[ERROR] Access to protected value EMPTY not permitted because
[ERROR] enclosing package metadata in package plan is not a subclass of
[ERROR] class RelMetadataQuery in package metadata where target is defined
[ERROR] this(RelMetadataQuery.THREAD_PROVIDERS.get, RelMetadataQuery.EMPTY)
[ERROR]
[ERROR] Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.2.2:compile (scala-compile-first) on project flink-table-planner-blink_2.12: wrap: org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]
Anyone an idea how to fix this?
Best regards,
Martijn

You can monitor https://issues.apache.org/jira/browse/FLINK-12392 for
the compile issue.

You are correct, that is a typo. Very well done for spotting it, will
fix it right away.
We can conclude that the current SNAPSHOT version does not build with
scala 2.12 at the moment; hopefully there aren't too many issues.
