Question

我正在尝试使用Rest Assured with TestNG创建一个项目，但我遇到了java.lang.NoClassDefFoundError: org/hamcrest/TypeSafeMatcher的问题。对此更新，所以任何帮助都表示赞赏。

我正在使用Maven：

<dependencies>
        <dependency>
            <groupId>io.rest-assured</groupId>
            <artifactId>rest-assured</artifactId>
            <version>3.0.3</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>io.rest-assured</groupId>
            <artifactId>json-schema-validator</artifactId>
            <version>3.0.3</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.8</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

Answer 1

你可以在你的pom中明确添加hamcrest依赖。

<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest-all</artifactId>
    <version>1.3</version>
</dependency>

我曾经多次遇到类似Hamcrest的问题，并且明确地添加它总是有帮助的。

Answer 2

我有完全相同的错误，除了我使用JUnit而不是TestNG。这对原始海报没有帮助，但我认为还有其他人喜欢我。

接受的答案对我不起作用，但我发现在我的POM中将JUnit之前的Rest Assured依赖项解决了问题（我在JUnit之后得到了Rest Assured）：

<dependencies>
    <!-- Other dependencies... -->
    <!-- Add dependency for Rest Assured (has to go before JUnit to work) -->
    <dependency>
        <groupId>io.rest-assured</groupId>
        <artifactId>rest-assured</artifactId>
        <version>3.0.6</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.10</version>
        <scope>test</scope>
    </dependency>
    <!-- Other dependencies... -->
</dependencies>

注释


您应该在pom.xml / build.gradle中的JUnit依赖项声明之前放心，以确保使用正确版本的Hamcrest。

REST Assured包含JsonPath和XmlPath作为传递依赖
