我们使用一个名为logback-ext- Cloudwatch appender的库将基于logback的日志发送到AWS Cloudwatch。这就是我们的pom.xml文件中的依赖项。
<dependency>
<groupId>org.eluder.logback</groupId>
<artifactId>logback-ext-cloudwatch-appender</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>几天前，这些错误开始出现在我们的日志中。

(truncated)我发现我们已经升级到AWS 1.11.5，但是我在那个版本中找不到任何这样的错误的证据。

事实证明，当前版本的logback-ext-cloudwatch-appender对AWS-java-sdk-log1.10.2的特定版本具有传递依赖关系，这是与其他aws库1.11.0和更高版本不兼容的。我们确实使用了许多其他库。我们把这种依赖排除在外。

<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-logs</artifactId>
<version>1.11.5</version>
</dependency>在这一点上，我们开始发现另一个错误。

at ch.qos.logback.classic.Logger.info(Logger.java:579)仅仅排除依赖项是行不通的。我不得不通过对当前1.11.5 aws库的依赖，分叉并重新构建logback-ext-cloudwatch-appender。试图将新的AWS依赖项与针对旧库构建的logback-ext-cloudwatch appender一起使用，会导致createLogGroup的方法签名(返回类型)不匹配，从而导致运行时错误。为了让它运行，我只需要在分叉版本中更改pom.xml文件，而不是源代码。
