Answer 1

如果发生以下情况之一，就会出现此问题：1）您要上传的json文件中的使用者/提供者名称中存在命名冲突。 解决方案：确保名称唯一，匹配规则不仅与子字符串匹配相关，而且还捕获“相似名称”。请检查Broker匹配代码以获取更多详细信息。 尚无相关文档。 示例：不允许Cart_service和order_service，因为它们具有通用词，所以不允许Car-order，order-processing。

2）如果有任何问题，运行mvn upload-pacts将返回NullPointerException。 要查看实际错误，请确保您改为运行mvn test或mvn install。 它将显示确切的服务器响应状态代码。

Answer 2

请参阅有关发布具有类似名称的服务的协议的文档：

409发布条约时

当协议正常发布时（通过PUT到/pacts/provider/PROVIDER/consumer/CONSUMER/version/CONSUMER_APP_VERSION ），将自动创建consumer ， provider和consumer version资源。

为了防止使用名称略有不同的名称（例如FooBar / foo-bar / foo bar / Foo Bar Service）多次创建一个人员（消费者或提供者），如果新的人员名称被认为与现有名称足够相似， 409将返回。 响应主体将包含指示，如果该名称应为现有名称，则应对其进行更正；如果该名称为新名称，则应手动创建该名称。

不幸的是，某些Pact Broker客户端在发生这种情况时不会显示完整的错误文本。 全文如下： This is the first time a pact has been published for "%{new_name}". The name "%{new_name}" is very similar to the following existing consumers/providers: %{existing_names} If you meant to specify one of the above names, please correct the pact configuration, and re-publish the pact. If the pact is intended to be for a new consumer or provider, please manually create "%{new_name}" using the following command, and then re-publish the pact: $ curl -v -XPOST -H "Content-Type: application/json" -d '{"name": "%{new_name}"}' http://broker/pacticipants If the pact broker requires authentication, include '-u <username>:<password>' in the command.
