Jackson databind error with scalatest Flatspec - scala

Question

I was trying to execute the scala test cases in IntelliJ using gradle with spark 3.1.1 & scala 2.12.13. But the scala tests were failing with the below jackson-databind error.
val conf = new SparkConf().setMaster("local[2]")
val spark = SparkSession
.builder()
.config(conf)
.appName("Scala Test Cases")
.getOrCreate()
spark.sparkContext.setLogLevel("ERROR")
import spark.implicits._
Error initializing SparkContext.

I'm importing scalatest & holdenkarau in build.gradle:
testImplementation("org.scalatest:scalatest_2.12:3.0.4") {
exclude group: 'com.fasterxml.jackson.core', module: 'jackson-databind'
}
testImplementation("com.holdenkarau:spark-testing-base_2.12:3.0.1_1.1.0"){
exclude group: 'org.apache.xbean', module: 'xbean-asm6'
}
These tests used to run fine when using spark 2.4.7 & scala 2.11.12 with below dependency versions.
testCompile("org.scalatest:scalatest_2.11:3.0.4")
testCompile("com.holdenkarau:spark-testing-base_2.11:2.4.5_0.14.0"){
exclude group: 'org.apache.xbean', module: 'xbean-asm6'
}
Not sure what am I missing here. I tried force updating the jackson libraries, but still it is not resolving the issue.
configurations.configureEach {
resolutionStrategy {
force "com.fasterxml.jackson.module:jackson-module-scala_2.12:2.12.4"
force "com.fasterxml.jackson.core:jackson-databind:2.12.4"
force "com.fasterxml.jackson.core:jackson-core:2.12.4"
force "com.fasterxml.jackson.core:jackson-annotations:2.12.4"
force "com.fasterxml.jackson.module:jackson-module-jaxb-annotations:2.12.4"
force "com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:2.12.4"
force "com.fasterxml.jackson.jaxrs:jackson-jaxrs-base:2.12.4"
force "org.scalatest:scalatest_2.12:3.0.4"
}
}

Answer 1

I added the below properties in dependency section that took care of jackson libraries.
implementation ('com.fasterxml.jackson.core:jackson-databind') {
version {
strictly "2.12.4"
}
}
implementation ('com.fasterxml.jackson.core:jackson-core') {
version {
strictly "2.12.4"
}
}
implementation ('com.fasterxml.jackson.core:jackson-annotations') {
version {
strictly "2.12.4"
}
}
