OK. I agree. I am gonna create a branch for spark-2.3/2.4. Regarding the
compiler used in each branch,

For Sedona on Spark 3.0, I will compile it using Scala 2.12
For Sedona on Spark 2.4, I will compile it using Scala 2.11.

For the Java code in both branches, I will compile them using Java 1.8

Am I missing anything here?
