Description

1. Unable to define expressions after executing the `build/sbt console` command

scala> val i = 1 // show
package $line3 {
  sealed class $read extends _root_.scala.Serializable {
    def <init>() = {
      super.<init>;
      ()
    };
    sealed class $iw extends _root_.java.io.Serializable {
      def <init>() = {
        super.<init>;
        ()
      };
      val i = 1
    };
    val $iw = new $iw.<init>
  };
  object $read extends scala.AnyRef {
    def <init>() = {
      super.<init>;
      ()
    };
    val INSTANCE = new $read.<init>
  }
}

2.  Due to the default unused imports check, the error "unused imports" will be reported after executing the `build/sbt sql/console` command

Welcome to Scala 2.13.12 (OpenJDK 64-Bit Server VM, Java 17.0.9).
Type in expressions for evaluation. Or try :help.

It is necessary to delete `-Wunused:imports` from both SparkBuild. sbt and pom.xml in order to avoid this error
