NoClassDefFoundError: com.amazonaws.http.AmazonHttpClient

Posted on

I have an issue on Fuse 7.2.0 with camel-aws and aws-java-sdk. We get the following exception when we configure a route:

com.my.package.aws.subsns:1.0.0.redhat-720035 (300)[subsns(20)] : The activate method has thrown an exception

We have resolved transitive dependency issues, but we still get the exception.
A wokaround is to exclude aws-java-sdk from camel-aws and add a dependency for aws-java-sdk-bundle.
Has anyone else run into this on Fuse 7.2?
Thanks
