Hello, Unfortunately, there are some more version issues:
The scala-11 profile doesn’t work with Java 11. This is because Spark 2.4.8 doesn’t support Java 11: https://stackoverflow.com/questions/62894890/spark-for-java-11 A simple “fix” would be to tell users to use only Java 8 with the scala-11 profile, and (if possible) also add this requirement in the pom with the <requireJavaVersion>. Do you think this would be an acceptable fix? (Both the scala-11 and scala-12 profiles work with Java 8. The scala-12 profile works with Java 11 also. Our Travis builds currently test only with Java 8.) Another issue is that the scala-13 profile doesn’t work at all. This is because neither Flink nor Spark supports scala-13 yet, see https://issues.apache.org/jira/browse/SPARK-25075 https://issues.apache.org/jira/browse/FLINK-13414 Is there a reason for adding this profile? I.e., is there some system that needs scala-13? If not, then maybe we should just comment out this profile for now to keep things simple, until Spark and/or Flink start supporting it. Best, Gábor
