由于超时错误，无法订阅更改数据捕获事件

Question

我正在尝试使用 Salesforce 更改数据捕获事件。我正在关注这篇文章：https://trailhead.salesforce.com/content/learn/modules/change-data-capture/subscribe-to-events

我已按照以下步骤操作：

To get a local copy of the EMP-Connector GitHub repository:

$ git clone  https://github.com/forcedotcom/EMP-Connector.git
To build the EMP-Connector tool:
$ cd EMP-Connector

$ mvn clean package
The mvn command generates JAR files in the target folder in the EMP-Connector project directory. 

生成的 JAR 文件 target/emp-connector-0.0.1-SNAPSHOT-phat.jar 包含连接器和 LoginExample 功能。 JAR 包含连接器的所有依赖项，因此您无需单独下载它们。 要针对您的 Developer Edition 或 Trailhead Playground 组织运行 EMP Connector， 键入此命令并提供您的 Trailhead Playground 组织或 Salesforce 组织登录凭据以及要订阅的频道。在此示例中，通道为 /data/Employee__ChangeEvent。

$ java -jar target/emp-connector-0.0.1-SNAPSHOT-phat.jar <username> <password> /data/Employee__ChangeEvent

最后一步后，我收到以下错误：

我看到 github 页面上打开了类似的问题 https://github.com/forcedotcom/EMP-Connector/issues/99

请提供解决此问题的建议

请检查 POM 是否有 slf4j 依赖。
