Spark Submit Command generator using Iceberg Catalog

TL;DR

• Pick a Spark version and the tool offers only the Iceberg releases that actually support it, read from each release’s own build, then only the Scala versions Iceberg publishes a runtime for.
• Spark 4.x is Scala 2.13 only, so no _2.12 Iceberg runtime exists for it. The tool will not let you build that coordinate.
• It emits the --packages coordinate, the IcebergSparkSessionExtensions config, and the catalog configs for Hive, Hadoop, REST or JDBC.
• SparkSessionCatalog is used for Hive so Iceberg and existing Hive tables coexist under one catalog name; every other type gets SparkCatalog.
