ktor:无法解析jacksonserializer

我尝试在Kotlin多平台项目的CommonMain模块中设置ktor HTTP客户端(如本文所述) https://ktor.io/clients/http-client/features/json-feature.html ,但无法解决对它的依赖关系:

    val client = HttpClient {
        install(JsonFeature) {
            serializer = JacksonSerializer()
        }
    }

Gradle版本:4.7。

以下是通用模块的build.grade:

apply plugin: 'kotlin-multiplatform'
apply plugin: 'kotlinx-serialization'

    kotlin {
        targets {
            // Change to `presets.iosArm64` to deploy the app to iPhone
            fromPreset(presets.iosX64, 'ios') {
                compilations.main.outputKinds('FRAMEWORK')
            }
        }
        sourceSets {
            commonMain.dependencies {

                }
            }
            iosMain {

        }
    }
