Trees In many command line interfaces, there is a command called tree that either already exists of you can download via a package manager. Delmar doesn't let us do that, unfortunately, so we'll have to build our own. For this project, your goal is to create a command line tool that takes in a directory, and prints all of its subdirectories in a formatted fashion. For example, suppose I pass in a directory with its own subdirectories for a project, I would expect an output as follows: example-app |-- [login to view URL] |-- src | |-- main | | `-- java | | `-- main | | |-- [login to view URL] | | `-- [login to view URL] | `-- test | `-- java | `-- main | |-- [login to view URL] | `-- [login to view URL] `-- target |-- classes | |-- [login to view URL] | `-- main | `-- [login to view URL] |-- generated-sources | `-- annotations |-- generated-test-sources | `-- test-annotations |-- maven-status | `-- maven-compiler-plugin | |-- compile | | `-- default-compile | | |-- [login to view URL] | | `-- [login to view URL] | `-- testCompile | `-- default-testCompile | |-- [login to view URL] | `-- [login to view URL] |-- surefire-reports | |-- [login to view URL] | |-- [login to view URL] | |-- [login to view URL] | `-- [login to view URL] `-- test-classes |-- [login to view URL] `-- main `-- [login to view URL] Your application should be able to: Determine the filetype of what is passed in, and throw an error / exit if not a directory. Print a tree of the file hierarchy of the supplied directory's subdirectories and files.
