Incorrect CodeUri for sam build

This CodeUri may be correct for other SAM commands, but if you run sam build it's incorrect. See https://github.com/awslabs/aws-sam-cli/issues/1278#issuecomment-512341533:

It looks like your CodeUri is a jar? It should be the directory of your source not the compiled artifact.

The error it gives:

Build Failed - Error: JavaMavenWorkflow:CopySource - [Errno 20] Not a directory: '/usr/aws-logs-loggroup/target/aws-logs-loggroup-handler-1.0-SNAPSHOT.jar

I fixed it by manually changing the template file:

CodeUri: ./target/aws-logs-loggroup-handler-1.0-SNAPSHOT.jar

to

CodeUri: .
