Spark Unit Tests Fails With java.lang.ExceptionInInitializerError(ScalaTest) - scala

Question

This is how my spark unit tests are written
class SparkReaderTest extends FunSuite with BeforeAndAfterAll{
#transient
var spark:SparkSession = _
override def beforeAll(): Unit = {
spark=
SparkSession
.builder()
.master("local[*]")
.appName("SparkScalaTest")
.getOrCreate()
}
override def afterAll(): Unit = {
spark.stop()
}
test("test for utilities for read operations"){
assert(txtToDFDefault("mockfiles.log",spark).count()>1,"reading raw data")
}
}
My pom.xml is like this

When I try to run mvn clean install command , it fails with the following error
