NoSuchMethodError: createLogGroup

Hey!

I am trying to use your library but i am getting this error.

Exception in thread "CloudWatchAppender" java.lang.NoSuchMethodError: com.amazonaws.services.logs.AWSLogsClient.createLogGroup(Lcom/amazonaws/services/logs/model/CreateLogGroupRequest;)V
    at com.j256.cloudwatchlogbackappender.CloudWatchAppender$CloudWatchWriter.verifyLogGroupExists(CloudWatchAppender.java:505)

    at com.j256.cloudwatchlogbackappender.CloudWatchAppender$CloudWatchWriter.run(CloudWatchAppender.java:369)
    at java.lang.Thread.run(Thread.java:748)

I have included in my pom.xml

<dependency>
    <groupId>com.j256.cloudwatchlogbackappender</groupId>
    <artifactId>cloudwatchlogbackappender</artifactId>
    <version>1.8</version>
</dependency>

Before of this, because I am using the aws-sdk, I have included:

<properties>
    <project.aws>1.11.109</project.aws>
</properties>
<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>${project.aws}</version>
</dependency>

Can you figure out what is happening?

Thanks!

Huh. I just ran my full integration test with that version and it works fine. I've been testing with 1.10.40 and I'd be surprised if the dropped backwards compatibility for something in the logs.

[destebanm]

Yes, It is really weird. I am using spring boot and taking a look to the lib folder, it is included the aws-java-sdk-log with version 1.11.109. In this version the method exists so I don´t understand what is happening

[j256]

Is it possible that a different version of the AWS SDK is loading than you think? Maybe it is a dependency from somewhere else?

Here is the same problem:

I did what he suggests, changing version in your pom and it works.

I have just create a pull request

Hey @destebanm . Give the 1.10 version a try. I think it fixes it. I switched to making the log-group and log-stream creation using reflection which seems to have fixed the method signature issue.

Hey @j256, i have been testing the 1.10 version and It´s working fine.

Thanks!
