+A task createPolarisSparkJar is added to build a jar for the Polaris Spark plugin, the jar is named as:

 The result jar is located at plugins/spark/v3.5/build/<scala_version>/libs after the build.
 
-The shadowJar task is also executed automatically when you run `gradlew assemble` or `gradlew build`.

 # Start Spark with Local Polaris Service using built Jar
 Once the jar is built, we can manually test it with Spark and a local Polaris service.

-## Iceberg Spark Client compatibility with Polaris Spark Client
-The Polaris Spark client today depends on a specific Iceberg client version, and the version dependency is described
-in the following table:
-
-| Spark Client Version | Iceberg Spark Client Version |
-|----------------------|------------------------------|
-| 1.0.0                | 1.9.0                        |
-
-The Iceberg dependency is automatically downloaded when the Polaris package is downloaded, so there is no need to
-add the Iceberg Spark client in the `packages` configuration.
