ScalaTest 加载套件时出现错误,Scala 签名套件版本错误

ScalaTest I get error while loading Suite, Scala signature Suite has wrong version

我有一个具有依赖项的 Maven 项目:

<dependency>
    <groupId>org.scalatest</groupId>
    <artifactId>scalatest_2.11</artifactId>
    <version>2.2.5</version>
    <scope>test</scope>
</dependency>

然后像这样测试 class 套件:

import java.util.{LinkedHashMap => jLinkedHashMap, ArrayList => jArrayList, Arrays}
import org.scalatest._


class NeutralizeEITSuite extends FunSuite with Matchers {

    val nEIT = new NeutralizeEIT()

    test("Valid content category 'MiniSeries' is neutralized to 'TV Entertainment':") {
        val result = neutralizedEIT(content_category = "MiniSeries")
        val content_category = getStringValueFromEIT("content_category", result)
        content_category should equal ("TV Entertainment")
    }
}

我在编译期间遇到一个我不明白的错误:

我尝试用谷歌搜索错误但没有结果。我的 pom.xml

中没有额外的 org.scalatest 依赖项

FunSuite 的 4.1 和 5.0 版本在哪里?

谢谢,

content_category 变量可能与前一行的 content_category 命名参数发生冲突。

问题已通过更新我的 pom 中的 scala 规范依赖项得到修复

    <dependency>
        <groupId>org.specs</groupId>
        <artifactId>specs</artifactId>
        <version>1.6.2.2_1.5.0</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.scala-tools.testing</groupId>
        <artifactId>specs</artifactId>
        <version>1.6.2.2_1.5.0</version>
    </dependency>

我是在 5 年后来到这里的,所以对于通过 Google 到达这里的任何人......这些天的答案是你的 [=] 中可能有旧版本的 org.specs 21=](可能是因为您从旧源复制粘贴),以及新的 org.scalatest 库。

如果两者都有,解决办法是删除这个:

<dependency>
  <groupId>org.specs</groupId>
  <artifactId>specs</artifactId>
  <version>[Some version]</version>
  <scope>test</scope>
</dependency>

只留下这个:

<dependency>
  <groupId>org.scalatest</groupId>
  <artifactId>scalatest_2.11</artifactId>
  <version>3.2.9</version>
  <scope>test</scope>
</dependency>

(其中 _2.11 替换为您正在使用的 Scala 版本,3.2.9 替换为您正在使用的 ScalaTest 版本。)
