junit和hamcrest声明

Question

我在4.10使用junit并在1.3处声明了hamcrest-core,在1.3处声明了hamcrest-library.我的问题是在junit 4.10中嵌入的hamcrest-library和hamcrest-core.junit 4.11怎么样？

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.10</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-core</artifactId>
        <version>1.3</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-library</artifactId>
        <version>1.3</version>
        <scope>test</scope>
    </dependency>

Answer 1

如果您浏览到search.maven.org,则可以搜索工件并查看其依赖项.如果您使用带有Maven插件的Eclipse,则还可以在POM编辑器中单击Dependency Hierarchy.

在Maven网站上看,您可以看到JUnit 4.11依赖于Hamcrest 1.3:

<dependencies>
    <dependency>
      <groupId>org.hamcrest</groupId>
      <artifactId>hamcrest-core</artifactId>
      <version>1.3</version>
      <scope>compile</scope>
    </dependency>
</dependencies>

Hamcrest库你必须自己添加.

Answer 2

JUnit 4.10和JUnit 4.11(如下所示):

   <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>

...分别使用hamcrest-core 1.1和1.3.你可以通过利用依赖插件的树目标(运行mvn依赖:树)来自己看到这个:

$ mvn dependency:tree

听起来很愚蠢,你需要包含适当的hamcrest-library artefact来利用Hamcrest Matchers.希望这有助于......
