Package h07

Class Installer

java.lang.Object

h07.Installer

public class Installer
extends Object

Installer for the community tests.

This is a standalone class that can download all necessary files to run tests for this assignment. More specifically, it can download all files whose hashes are listed in .test_metadata.xml. This class can also be used to reset or rather re-download files that have become corrupted or have otherwise been modified.

It is important that the working directory is the same as the project root directory when running main(String[]), otherwise the files might be downloaded to the wrong location or even overwrite other files!
