Make a code change
Open the file sam-app/HelloWorldFuction/src/main/java/helloworld/App.java and make a simple code change. For
example, change the response message to return hello my friend instead of hello world.
Note: Make sure you save the file after changing it.
When using Python or Node, you don’t have to restart the sam local process, just refresh the browser
tab or re-trigger the CURL command to see the changes reflected in your endpoint. However, when using Java, you will need
to rebuild the module with sam build for ech change.
You also need to restart sam local if you change the template.yaml.
