In this chapter we learned about the support that Gradle gives when working with files. We saw how to create a file or directory and a collection of files and directories. A file tree represents a hierarchical set of files.

We can add logging messages to our project and tasks and see the output when we run a Gradle build. We learned how to use different log levels to influence how much information is shown in the output. We also used LoggingManager to capture standard output and error messages and redirect them to custom log levels.

We learned how we can use the Gradle wrapper to allow users to build our projects even if they don't have Gradle installed. We learned how we can customize the wrapper to download a specific version of Gradle and use it to run our build.

In the next chapter, we will create a Java project and use the Java plugin to add a set of default tasks we can use to compile, test, and package our Java code.
