Errors while creating EC2 specific API Clients when using jclouds 1.7.1 - No implementation bound for @com.google.inject.name.Named at bindImageSupplier.

["Varad Meru (Orzota)" <va...@orzota.com>]

Hi All,

I am trying to use cloud-specific APIs to generate EC2 security groups 
and keypair, but I am not able to create the new clients using the the 
method mentioned in the 
documentation(http://jclouds.apache.org/guides/aws/), which uses 
AWSEC2Client class.

 From documentation -
// when you need access to very ec2-specific features, use the 
provider-specific context
AWSEC2Client ec2Client = 
AWSEC2Client.class.cast(context.getProviderSpecificContext().getApi());

/But this class is not available in 1.7.1.///

After some digging, I found *AWSEC2Api *(org.jclouds.aws.ec2.AWSEC2Api) 
to provide different clients with similar functionality as the 
AWSEC2Client. (This is not mentioned in the documentation as well.). But 
it is causing the exception to be thrown. Please have a look let me know 
if I am doing something wrong.

Regards,
Varad

PS: Please find code snippet, pom.xml entries and stacktrace below.

Could you try simply with .newBuilder("aws-ec2") in the above code  
snippet? And jclouds 1.7.2 is out, by the way - not that I expect that  
to change what you're seeing, though.
