使用spring云契约时的APi不兼容性

Question

我试图在一个示例生产者项目中使用spring合同。然而，由于以下原因，我在POM中看到了错误

Multiple annotations found at this line:
    - Execution default-generateTests of goal org.springframework.cloud:spring-cloud-contract-maven-plugin:1.2.4.RELEASE:generateTests failed: An API 
     incompatibility was encountered while executing org.springframework.cloud:spring-cloud-contract-maven-plugin:1.2.4.RELEASE:generateTests:

     Stackmap Table: append_frame(@13,Object[#83])

我正在使用SpringBoot1.5.14 contract，Edgware.SR3，Java1.8和Spring contract plugin 1.2.4。

我试着使用Spring合同在线教程中的例子，尝试使用插件、spring和spring启动的版本，但我似乎无法消除不兼容错误。

我成功地构建了你的项目。你的合同有错误(报价太多)

import org.springframework.cloud.contract.spec.Contract;

Contract.make{
    request{
        method 'POST'
        url '/credit-scores'
        body """
            {
                "citizenNumber" : 1234
            }
            """ // you had an extra quote here
        headers{
            contentType applicationJson()
        }
    }
    response{
        status 200
        body """
            {
                "score" : "HIGH"
            }
            """
        headers{
            contentType applicationJson()
        }
    }
}

执行

➜  creditcheckservice-producer git:(Phase2) ✗ ./mvnw clean install
...

更新：

结果发现java版本中存在不匹配现象。
