Pact提供者测试出现InitializationError，消费者可正常上传契约

同一台机器上，消费者侧可成功将契约上传至PactFlow Broker，但运行提供者契约测试时出现初始化错误，日志如下：

推测JUnitRunner无法找到测试用例，怀疑是防火墙或认证问题，参考相关资料后未解决。

消费者上传契约的Maven插件配置 #

<plugin>
            <groupId>au.com.dius.pact.provider</groupId>
            <artifactId>maven</artifactId>
            <version>4.1.17</version>
            <configuration>
                <pactBrokerUrl>https://akbank.pactflow.io</pactBrokerUrl>
                <pactBrokerToken>MyToken</pactBrokerToken>
            </configuration>
        </plugin>

提供者JUnit测试类注解配置 #

@PactUrl(
    urls="https://akbank.pactflow.io/pacts/provider/fatura-service/consumer/Mobil Mudurluk Fatura Ekibi/latest", 
    auth = @Authentication(token = "MyToken"))

本地测试特殊情况 #

使用@PactFolder("pacts")时测试可正常运行，但必须依赖au.com.dius:pact-jvm-provider-spring_2.12:3.5.24版本，否则会出现Gson方法找不到异常。
