Preparing for this chapter

In this chapter, I continue to use the webapp project from Chapter 7. No changes are required to prepare for this chapter. Open a command prompt, navigate to the webapp folder, and run the command shown in Listing 8.1 to start the build tools.

Listing 8.1: Starting the build tools
