sbt assembly assemblyShadeRules not shading dependency

Question

I am trying to shade com.google.gson to my_gson and added assemblyShadeRules to my build.sbt:

assemblyShadeRules in assembly ++= Seq(
  ShadeRule.rename("com.google.gson.**" -> "my_gson.@1")
    .inLibrary("com.google.code.gson" % "gson" % "2.8.9")
    .inProject
)

According to this: how to shade before compile with SBT? when we shade the dependency using assemblyShadeRules, the import statement should change and be updated from e.g.

import com.google.gson.{Gson, JsonArray, JsonObject}

into my_gson.{Gson, JsonArray, JsonObject}

The thing is it is still shwoing as com.google.gson I am unsure why. i am currently using intellij as my IDE but the change is not reflected even after i did the shading as per My build.sbt here:

name := "CMS Leakage Detection"

version := "3.0"

scalaVersion := "2.12.15"

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-sql" % "3.3.0",
  "com.google.code.gson" % "gson" % "2.8.9",
  "com.google.cloud.spark" %% "spark-bigquery-with-dependencies" % "0.26.0" % "provided",
  "com.typesafe" % "config" % "1.3.2",
  "com.jcraft" % "jsch" % "0.1.55",
  "org.springframework" % "spring-web" % "5.3.18",
  "org.apache.httpcomponents" % "httpcore" % "4.4.15",
  "org.apache.httpcomponents" % "httpclient" % "4.5.13"
)

excludeDependencies ++= Seq(
  ExclusionRule("org.apache.hadoop", "commons-logging")
)

scalacOptions ++= Seq("-Xmax-classfile-name","80")

assemblyMergeStrategy in assembly := {
  case PathList("META-INF", _*) => MergeStrategy.discard
  case _                        => MergeStrategy.first
}

assemblyShadeRules in assembly ++= Seq(
  ShadeRule.rename("com.google.gson.**" -> "my_gson.@1")
    .inLibrary("com.google.code.gson" % "gson" % "2.8.9")
    .inProject
)

I am expecting the import statement to show: e.g.)

import my_gson.JsonObject

running jar tvf .../path-to-my-jar is also showing that the dependency is not shaded, output: Fri Jan 01 00:00:00 SGT 2010 com/google/gson/JsonObject.class

i created a file called plugins.sbt inside my project folder /Users/myname/Desktop/repo/projIamWorkingOn/project/plugins.sbt and it contains only the following, its so that i can use sbt assembly

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "1.2.0")
