Welcome to Config Patcher!

The Java JDK is used to compile Config Patcher.

Download and install the Java JDK.
- Windows/Mac download link. Scroll down, accept the Oracle Binary Code License Agreement for Java SE, and download it (if you have a 64-bit OS, please download the 64-bit version).
- Linux: Installation methods for certain popular flavors of Linux are listed below. If your distribution is not listed, follow the instructions specific to your package manager or install it manually here.
  - Gentoo: emerge dev-java/oracle-jdk-bin
  - Archlinux: pacman -S jdk7-openjdk
  - Ubuntu/Debian: apt-get install openjdk-7-jdk
  - Fedora: yum install java-1.7.0-openjdk
Set up the environment.
- Windows: Set environment variables for the JDK.
  1. Go to Control Panel\System and Security\System, and click on Advanced System Settings on the left-hand side.
  2. Click on Environment Variables.
  3. Under System Variables, click New.
  4. For Variable Name, input JAVA_HOME.
  5. For Variable Value, input something similar to C:\Program Files\Java\jdk1.7.0_45 exactly as shown (or wherever your Java JDK installation is), and click Ok.
  6. Scroll down to a variable named Path, and double-click on it.
  7. Append ;%JAVA_HOME%\bin EXACTLY AS SHOWN and click Ok. Make sure the location is correct; double-check just to make sure.
Open up your command line and run javac. If it spews out a bunch of possible options and the usage, then you're good to go. If not try the steps again.

Git is used to clone Config Patcher and update your local copy.

Download and install Git here.
Optional Download and install a Git GUI client, such as Github for Windows/Mac, SmartGitHg, TortoiseGit, etc. A nice list is available here.

This section assumes that you're using the command-line version of Git.

Open up your command line.
Navigate to a place where you want to download Config Patcher's source (eg C:\Development\Github\Minecraft\) by executing cd [folder location]. This location is known as mcdev from now on.
Execute git clone git@github.com:Lunatrius/Config-Patcher.git. This will download Config Patcher's source into mcdev.
Right now, you should have a directory that looks something like:

mcdev
\-ConfigPatcher
    \-ConfigPatcher's files (should have build.gradle)

Execute gradlew setupDevWorkspace. This sets up Forge and downloads the necessary libraries to build Config Patcher. This might take some time, be patient.
- You will generally only have to do this once until the Forge version in build.properties changes.
Execute gradlew build. If you did everything right, BUILD SUCCESSFUL will be displayed after it finishes. This should be relatively quick.
- If you see BUILD FAILED, check the error output (it should be right around BUILD FAILED), fix everything (if possible), and try again.
Go to mcdev\ConfigPatcher\build\libs.
- You should see a .jar file named ConfigPatcher-#.#.#-#.#.#.#-universal.jar.
Copy the jar into your Minecraft mods folder, and you are done!

In order to get the most up-to-date builds, you'll have to periodically update your local repository.

Open up your command line.
Navigate to mcdev in the console.
Make sure you have not made any changes to the local repository, or else there might be issues with Git.
- If you have, try reverting them to the status that they were when you last updated your repository.
Execute git pull master. This pulls all commits from the official repository that do not yet exist on your local repository and updates it.

Shamelessly based this README off pahimar's version.
