無法在scala playframework上運行單元測試

Question

我是新玩法框架。我正在嘗試運行單元測試。這是我的OneTimeTestSuite文件。這裏是它的代碼。

package com.sentrana.mmcore.test 

import org.scalatest.{ DoNotDiscover, Suites } 
import org.scalatestplus.play.OneAppPerSuite 
import play.api.test.FakeApplication 
import com.sentrana.mmcore.controllers.MetaDataSpec 
import com.sentrana.Global 

class OneTimeTestSuite extends Suites(
    new MetaDataSpec 
) with OneAppPerSuite { 
    implicit override lazy val app: FakeApplication = 
    FakeApplication(withGlobal = Some(Global), additionalConfiguration = Map(
     "ConfigSubFolderLocation" -> "/conf/" 
    )) 
} 

這裏是MeteDataSpec文件中的代碼。

package com.sentrana.mmcore.controllers 

import play.api.Play 
import play.api.Play.current 
import org.joda.time.DateTime 
import org.scalatestplus.play.{ PlaySpec, ConfiguredApp } 
import play.api.libs.json.{ JsValue, Json } 
import play.api.mvc.Cookie 
import play.api.test.FakeRequest 
import play.api.test.Helpers._ 
import org.json4s.native.Serialization._ 
import play.api.test._ 

class MetaDataSpec extends PlaySpec with ConfiguredApp { 
    "GetCustomers" should { 
    "get all the customers" in { 
     val response = route(FakeRequest(GET, "/api/shop/v0.1/metadata/customers")).get 
    } 
    } 
} 

我正在使用scalatestplus。

這是我正在運行的測試命令。

test-only com.sentrana.mmcore.test.OneTimeTestSuite

這是錯誤我得到

java.lang.NoSuchMethodError: play.core.Router$HandlerDef.<init>(Ljava/lang/Object;Ljava/lang/String;Ljava/lang/String;Lscala/collection/Seq;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V

這是我build.sbt文件。

我希望我已經明確提出了我的問題。如果有任何混淆，請詢問。提前致謝。

您的項目被標記爲scala 2.11，但您使用的是2.10的json4s。 Scala在主要版本之間沒有二進制兼容性。

更改依賴於像

"org.json4s" %% "json4s-mongo" % "3.2.10", 
"org.json4s" %% "json4s-ext" % "3.2.10", 

的%%自動添加斯卡拉版本爲後綴的神器的名字，這是斯卡拉公約
