IntelliJ community maven pom.xml错误，建议cucumber jar版本冲突

Question

我在maven pom.xml文件中得到这个版本冲突错误：

在将gherkin版本更新到18.0.0之后，依赖项部分得到了修复，但是在运行测试运行程序时，我得到了以下错误：

Answer 1

您的依赖项不一致。您正在混合Cucumber的多个版本，并包括传递依赖项。

因此，我强烈建议您投入时间学习如何使用Maven（或Gradle）。理解这些工具和所涉及的概念可以使您的生活轻松得多。

例如：

    <properties>
        <cucumber.version>5.2.0</cucumber.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>${cucumber.version}</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-junit</artifactId>
            <version>${cucumber.version}</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

通过告诉Maven您的依赖项是什么，Maven可以计算您的传递依赖项，即：依赖项的依赖项。

这有很多好处。一个例子是使用MVN dependency:tree命令列出所有依赖项及其传递依赖项。
