将Rest Assured RequestSpecification与testng

Question

我使用rest assured 2.3.4版本和testng来测试rest API，我得到了以下错误

java.lang.IncompatibleClassChangeError: the number of constructors during runtime and compile time for com.jayway.restassured.internal.RequestSpecificationImpl$EncodingTarget do not match. Expected -1 but got 2

我的方法如下所示，

public Response restPostOperation(String resource,String PayLoad) throws IOException{

        String  methodName="restPostOperation";
        log.info("Executing the method {} in class {} begins",methodName,className);
        try{
            RequestSpecBuilder builder = new RequestSpecBuilder();
            //Setting content type as application/json or application/xml
            builder.setContentType("application/xml; charset=UTF-8");
            //Setting Request body  
            builder.setBody(PayLoad);
            RequestSpecification requestSpec = builder.build();
            configurePreResourcePath();
            response=given().spec(requestSpec).when().post(resource);
            log.info("Executing the method {} in class {} ends",methodName,className);
            return  response;
        }catch(Exception ex){
            System.out.println("Request can not be processed.An Exception has been Occured "+ex);
            throw ex;
        }
    }

我不明白为什么会这样。如果你遇到类似的问题，有人能帮我吗

似乎在类路径中有一个错误的groovy版本。如果您使用Maven/Gradle中的任何一个库，请尝试将rest assured依赖项作为第一个库。
