Question

创建了一个Maven项目并添加了以下依赖项。因此，当我运行功能文件时，我收到错误：

Exception in thread "main" java.lang.NoClassDefFoundError: io/cucumber/datatable/dependency/com/fasterxml/jackson/databind/JavaType
    at io.cucumber.datatable.DataTableType.<init>(DataTableType.java:78)

我使用的JDK也是jdk1.8.0_121。

有人可以告诉我如果我错过任何图书馆或需要修改任何内容吗？这可能是一个简单的问题，但我无法找到解决方案，因为我刚刚开始使用Cucumber框架。

Answer 1

要将Cucumber与JUnit一起使用，您只需要以下依赖项，您可以在Cucumber文档here和here中找到：

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-java8</artifactId>
    <version>3.0.2</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>3.0.2</version>
    <scope>test</scope>
</dependency>    

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

注意：

确保对所有Cucumber依赖项使用相同的 Cucumber版本;否则你可能会得到一些不可预知的行为。

尚不支持JUnit 5.

Answer 2

确保在maven项目中使用黄瓜依赖项时，请尽可能使所有依赖项保持相同版本。

而且，如果您使用的黄瓜罐组ID为info.cukes，则将所有依赖项用于同一组。

如果要升级，请使用带有io.cucumber的最新罐3.x。

Answer 3

添加

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>datatable</artifactId>
    <version>1.1.12</version>
</dependency>

到您的POM

经过一番研究后终于明白了。以下依赖关系已解决问题。
