Extra dependencies

Our parent project, serverless-cookbook-parent-aws-java, defines a few more dependencies than I have. You can download them automatically through Maven (these projects are already available in Maven Central) or set these up manually in your local machine (to examine or modify) by executing the following commands from the command line. 

1. Go inside the parent folder (serverless in my case) and clone the simple-starter-build-tools project:

git clone https://github.com/heartin/simple-starter-build-tools.git

1. Go inside the project folder and run mvn clean install, as follows:

cd simple-starter-build-tools
mvn clean install

1. Go back to the parent folder (serverless in my case) and clone the simple-starter-parent-java project:

git clone https://github.com/heartin/simple-starter-parent-java.git

1. Go inside the project folder and run mvn clean install:

cd simple-starter-parent-java
mvn clean install
