通过 Windows 命令行的 Cucumber (Java) 通过批处理工作，但不是 pom

Question

我正在运行通过 Windows 命令行上的 Cucumber For Java 书中的示例。我可以从 Windows 批处理文件中很好地执行它，但是当尝试从 Maven 执行它时，我得到 "No sources to compile" 和 "No tests to run"。 pom 中需要什么才能指向与批处理中相同的 classes/features？

    Scenario Outline: Checkout bananas
        Given the price of a "banana" is 40c
        When I checkout <count> "banana"
        Then the total price should be <total>c
        Examples:
        | count | total |

        | 2     | 80    |
    Scenario: Two bananas scanned separately
        Given the price of a "banana" is 40c
        When I checkout 1 "banana"
        And I checkout 1 "banana"
        Then the total price should be 80c
    Scenario: A banana and an apple
        Given the price of a "banana" is 40c

将 cucumber-jvm 与 Maven 一起使用时，项目需要遵守 Maven 约定，以便 cucumber-jvm 可以选取不同的文件。如果使用 maven-surefire-plugin:

特征文件需要存放在src/test/resources;
步骤定义需要存储在src/test/java;
用 @RunWith(Cucumber.class) 注解的单元测试需要存储在 src/test/java.

然后可以执行测试运行 mvn test。你可以查看 this example 我穿上了 github.
