getting Run crashed when i run the Karate gatling with Gradle - gradle

Question

package mock
import com.intuit.karate.gatling.PreDef._
import io.gatling.core.Predef._
import scala.concurrent.duration._
class CatsKarateSimulation extends Simulation {
MockUtils.startServer()
val feeder = Iterator.continually(Map("catName" -> MockUtils.getNextCatName))
val protocol = karateProtocol(
"/cats/{id}" -> Nil,
"/cats" -> pauseFor("get" -> 15, "post" -> 25)
)
protocol.nameResolver = (req, ctx) => req.getHeader("karate-name")
val create = scenario("create").feed(feeder).exec(karateFeature("classpath:mock/cats-create.feature"))
val delete = scenario("delete").group("delete cats") {
exec(karateFeature("classpath:mock/cats-delete.feature#name=delete"))
}
val custom = scenario("custom").exec(karateFeature("classpath:mock/custom-rpc.feature"))
setUp(
create.inject(rampUsers(10) during (5 seconds)).protocols(protocol),
delete.inject(rampUsers(5) during (5 seconds)).protocols(protocol),
custom.inject(rampUsers(10) during (5 seconds)).protocols(protocol)
)
}
Can anyone help why I am getting this error:
Currently my project has karate api scripts and there are few java helper classes in it, i need to implement the Gatling with gradle.
Java: 11
Gradle: Gradle 7.5.1
Windows 10
Eclipse IDE
build.gradle
