Error:- java.lang.NoClassDefFoundError: scala/Product$class - scala

Question

Test project Build.sbt
scalaVersion := "2.12.8"
crossScalaVersions := Seq("2.11.12", "2.12.8")
val scalaTestVersion = "3.0.5"
val rocksDBVersion = "5.17.2"
val kafkaVersion = "2.2.0"
lazy val deps = Seq(
// "javax.ws.rs" % "javax.ws.rs-api" % "2.1" jar(),
"org.apache.kafka" % "kafka-clients" % kafkaVersion,
"org.apache.kafka" % "kafka-clients" % kafkaVersion classifier "test",
"org.apache.kafka" % "kafka-streams" % kafkaVersion,

"org.rocksdb" % "rocksdbjni" % rocksDBVersion % "test"
)
Test Project plugins.sbt
addSbtPlugin("com.github.gseitz" % "sbt-release" % "1.0.8")
This is my Test application sbt configuration file and when I run sbt package it will create a jar file for me then I have to use that jar in my other project.
Other project sbt file
scalaVersion := "2.12.6"
object Dependencies {
val deps = Seq(
"org.json4s" %% "json4s-native" % "3.5.3",
"ch.qos.logback" % "logback-classic" % "1.2.3",

)
}
Other Project plugins.sbt

As I'm new in Scala and I don't know what i did wrong in that as when i put my test scala jar into another project It will give me the error.
Error:-
java.lang.NoClassDefFoundError: scala/Product$class
[error] at com.shepherd.kafka.streams.test.kit.MockedStreams$Builder.<init>(MockedStreams.scala:17)
[error] at com.shepherd.kafka.streams.test.kit.MockedStreams$.apply(MockedStreams.scala:15)

[error] at scala.runtime.java8.JFunction0$mcV$sp.apply(JFunction0$mcV$sp.java:12)
Can anyone please help me on this as I'm new also I have see this one java.lang.NoClassDefFoundError: scala/Product$class but this not help me so I have put my problem here.
Try with both the way like uploaded jar directly into the code and pull by S3 but the error is still exists.
resolvers += "Java.net Maven2 Repository" at "https://repo1.maven.org/maven2/"
resolvers += "S3" at "https://s3-eu-west-1.amazonaws.com/com.abc/" -> Test jar file
NOTE:- I have Set the same scala version in my both the application "2.12.6" but issue is still exists.
