For which Scala 2.12 version are you trying to compile? Flink supports Scala versions up to 2.12.7, since 2.12.8 introduced a binary incompatibility. Most likely (but not tested) you can compile for a different Scala version by using mvn clean install -DskipTests -Djapicmp.skip -Dscala-2.12 -Dscala.version=2.12.15
