标签： java spring rest-assured spring-cloud-contract

我正在尝试设置最新版本的spring cloud合约。但它始终抛出异常，无法初始化。我的gradle看起来像这样。我可以在外部库中看到，2.9.0是可见的。

dependencies {
    classpath "org.springframework.boot:spring-boot-gradle-plugin:2.0.0.M7"
    classpath "org.springframework.cloud:spring-cloud-contract-gradle-plugin:1.2.2.RELEASE"
    classpath "com.jayway.restassured:rest-assured:2.9.0"
    classpath "com.jayway.restassured:spring-mock-mvc:2.9.0"
}

dependencyManagement {
imports {
    mavenBom "org.springframework.cloud:spring-cloud-dependencies:Edgware.RELEASE"
 }
}
testCompile ("com.jayway.restassured:rest-assured:2.9.0")
        {
            force = true
        }
testCompile ("com.jayway.restassured:spring-mock-mvc:2.9.0")
        {
            force = true
        }

以下是例外：

Spring Cloud Contract 1.2.x与Boot 2.0.0不兼容。请使用Spring Cloud Contract 2.0.x。您正在使用与Spring Boot 2.0不兼容的Edgware BOM。请使用Finchley BOM。
