If anyone can help me, i really appreciate it

CodePudding user response：

Your dependencies are inconsistent. You are explicitly excluding transitive dependencies of Cucumber and explicitly including others. You shouldn't do that, Cucumber needs those to function.

I would strongly urge you to invest time in learning how to use Maven (or Gradle) beyond a superficial level. Understanding these tools and the concepts involved can make your life much easier.

For example:

If you want to use Cucumber with JUnit 5 and annotation based step definitions you would declare this minimal set of dependencies in a Maven pom.xml file.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.junit</groupId>
            <artifactId>junit-bom</artifactId>
            <version>5.9.1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-bom</artifactId>
            <version>7.10.1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit-platform-engine</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.junit.platform</groupId>
        <artifactId>junit-platform-suite</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <scope>test</scope>
    </dependency>

</dependencies>

By telling Maven what your dependencies are Maven can calculate your transitive dependencies i.e: the dependencies of your dependencies.

This has many advantages. One example would be using the mvn dependency:tree -Dverbose command to will list all dependencies and their transitive dependencies.

$ mvn dependency:tree -Dverbose

Note: If you see a transitive dependency listed as "omitted for duplicate" and you have also included it in your pom.xml, this inclusion isn't needed. Maven will download it for you.

Also if you are looking to make a fresh start, you could also use the cucumber-java-skeleton to start with a working project.
