Hi, In my Java application I use a TransportClient. It was working just fine until I tried to upgrade cloud aws to 2.5.1. I'm now getting the following exception when trying to instantiate the TransportClient: ``` org.elasticsearch.common.inject.CreationException: Guice creation errors: 1) A binding to org.elasticsearch.cloud.aws.AwsS3Service was already configured at _unknown_. at _unknown_ 2) A binding to org.elasticsearch.cloud.aws.AwsEc2Service was already configured at _unknown_. at _unknown_ 2 errors at org.elasticsearch.common.inject.internal.Errors.throwCreationExceptionIfErrorsExist(Errors.java:344) at org.elasticsearch.common.inject.InjectorBuilder.initializeStatically(InjectorBuilder.java:151) at org.elasticsearch.common.inject.InjectorBuilder.build(InjectorBuilder.java:102) at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:93) at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:70) at org.elasticsearch.common.inject.ModulesBuilder.createInjector(ModulesBuilder.java:59) at org.elasticsearch.client.transport.TransportClient.(TransportClient.java:187) at org.elasticsearch.client.transport.TransportClient.(TransportClient.java:123) ``` Any idea what could be wrong? Thanks, Maxime ---
