我正在尝试将Spock框架添加到我的Spring Boot项目中，但是我可以使其工作。我添加了那些依赖项：

       <!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<dependency>
    <groupId>org.spockframework</groupId>
    <artifactId>spock-core</artifactId>
    <version>1.2-groovy-2.5</version>
    <scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-spring -->
<dependency>
    <groupId>org.spockframework</groupId>
    <artifactId>spock-spring</artifactId>
    <version>1.2-groovy-2.5</version>
    <scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.codehaus.gmavenplus/gmavenplus-plugin -->
<dependency>
    <groupId>org.codehaus.gmavenplus</groupId>
    <artifactId>gmavenplus-plugin</artifactId>
    <version>1.6</version>
</dependency>

然后我创建了这个测试：

@SpringBootTest(classes = EdoobyApiApplication.class)
    class AddressServiceSpockTest extends Specification {

        def "when context is loaded then all expected beans are created"() {
             expect:
             1 + 1 == 3
        }

    }

这是我在EdoobyApiApplication.java中拥有的

@SpringBootApplication
@EntityScan(basePackageClasses = { 
        EdoobyApiApplication.class,
        Jsr310JpaConverters.class 
})
public class EdoobyApiApplication {

    @PostConstruct
    void init() {
        TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
    }

    public static void main(String[] args) {
        SpringApplication.run(EdoobyApiApplication.class, args);
    }

    @Bean
    public ObjectMapper getObjectMapper(){
        return new ObjectMapper();
    }
}

当我尝试运行测试时，出现此错误：

我不熟悉Spock，所以不确定是否应该添加任何其他依赖项或任何其他配置。另外我不确定我应该在@SpringBootTest上添加EdoobyApiApplication。如果有人能给我指引的方向，那就太好了。

谢谢！

这不是一个斯波克或Spring问题。

如果在编译类时运行时方法签名与方法签名不匹配，则Java将抛出 NoSuchMethodError 。 NoClassDefFoundError 。

在这种情况下，似乎提供了com.google.common.base.Preconditions.checkState方法的Guava版本，该方法是针对不匹配方法编译的Springfox springfox.documentation.spring.web.scanners.CachingOperationReader 类运行时（或可能是测试）类路径中方法的签名。

您应按照here中的说明运行mvn dependency:tree -Dverbose -Dincludes=com.google.guava:guava。找到哪个依赖项带来了与Springfox所需版本相冲突的Guava版本后，您可以在该其他依赖项中添加排除项，或者在项目中添加Springfox所需版本的显式依赖项，以确保运行/测试类路径包含兼容版本。
