NoSuchMethodError:okhttp3.HttpUrl.get（Ljava/lang/String；）Lokhttp3/HttpUrl在使用改型2时

我使用改装2发送http请求，代码如下：

            ReconcileService service = RetrofitUtil.InitRetrofitOkhttp().create(ReconcileService.class);
            Call<ResponseBody> call = service.page(request);
            ResponseBody body = call.execute().body();
            String str = new String(body.bytes(), "UTF-8");
            ObjectMapper mapper = new ObjectMapper();
            Response response = mapper.readValue(str, Response.class);

gradle :soa-illidan:soa-illidan-service:dependencies --configuration runtimeClasspath|grep -v "(*)"|grep -C 10 "okhttp"

但运行此代码时，它会给我提示：

    at java.lang.Thread.run(Thread.java:748) [na:1.8.0_212]

我试图从互联网上找到答案，但所有人都要求升级okhttp版本。但现在我的okhttp版本已经是4.0了，这是我的gradle配置：

api("com.squareup.okhttp3:okhttp:4.0.0")
api "com.squareup.retrofit2:converter-gson:2.8.1"

那么问题出在哪里？我应该如何解决它呢？

我使用gradle命令检查引用，如下所示：

            ReconcileService service = RetrofitUtil.InitRetrofitOkhttp().create(ReconcileService.class);
            Call<ResponseBody> call = service.page(request);
            ResponseBody body = call.execute().body();
            String str = new String(body.bytes(), "UTF-8");
            ObjectMapper mapper = new ObjectMapper();
            Response response = mapper.readValue(str, Response.class);

gradle :soa-illidan:soa-illidan-service:dependencies --configuration runtimeClasspath|grep -v "(*)"|grep -C 10 "okhttp"

并找到okhttp jar的实际版本是3.8.1：

$ gradle :soa-illidan:soa-illidan-service:dependencies --configuration runtimeClasspath|grep -v "(*)"|grep -C 10 "okhttp"

    'dependencies.dependency.systemPath' for com.alibaba:tools:jar must specify an absolute path but is ${env.JAVA_HOME}/lib/tools.jar in com.alibaba:druid:1.1.9

因此，我在

buil.gradle

中添加了这一点，以强制使用okhttp的4.0.0版本：

 resolutionStrategy {
            eachDependency { DependencyResolveDetails details ->
               
                if (details.requested.group == 'com.squareup.okhttp3') {
                    details.useVersion "4.0.0"
                }
            }
        }

问题解决了。希望对你有帮助
