Windows Prerequisites

1. WARNING: Make sure you know EXACTLY what you're doing! It's not any of our faults if your OS crashes, becomes corrupted, etc.
2. Download and install the Java JDK here. 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.)
   • Go to Control Panel\System and Security\System, and click on Advanced System Settings on the left-hand side.
   • Click on Environment Variables.

• Under System Variables, click New.
• For Variable Name, input JAVA_HOME.
• For Variable Value, input something similar to ;C:\Program Files\Java\jdk1.7.0_40 exactly as shown to the end (or wherever your Java JDK installation is), and click Ok.
• Scroll down to a variable named Path, and double-click on it.
• Append ;%JAVA_HOME%\bin, and click Ok.

3. Download Apache Ant here.
   • Unzip the files anywhere you want, eg C:\Program Files\Ant.

• Again, go to Environment Variables just like you did for the Java JDK.
• Under System Variables, click New.
• For Variable Name, input ANT_HOME.
• For Variable Value, input C:\Ant\apache-ant-1.9.2 (or your Ant directory\apache-ant-1.9.2).
• Scroll down to Path, and double-click on it.
• Append ;%ANT_HOME%\bin exactly as shown to the end.

4. Download and install Github here NOTE: This Github application is optional, you can use whatever you want, e.g. TortoiseGit.
   • Create an account.

• Scroll to the top of this page, login at the top-right, and then click Clone to Windows at the bottom of the right-hand toolbar.
• You should see Github flash and pahimar/Equivalent-Exchange-3 appear. (The local repository on Windows defaults to C:\Users\(username)\Documents\GitHub\Equivalent-Exchange-3, you can change it if you want but then you have to find it again on Github).

5. Create an empty directory for EE3 development. This directory is referenced as mcdev from now on. It can be where you cloned EE3, but it'll be a little messy.

Linux Prerequisites

1. Make sure you have the latest Java JDK installed. To install manually, go here. Otherwise, install from the package manager or the terminal (listed).
   • In Gentoo, emerge dev-java/oracle-jdk-bin
   • In Archlinux, pacman -S jdk7-openjdk
   • In Ubuntu/Debian, apt-get install openjdk-7-jdk
   • In Fedora, yum install java-1.7.0-openjdk
     • If your distribution is not listed, follow the instructions specific to your package manager.
2. Install Apache Ant. To install manually, go here.
   • In Gentoo, emerge dev-java/ant
   • In Archlinux, pacman -S apache-ant
   • In Ubuntu/Debian, apt-get install ant
   • In Fedora, yum install ant
     • If your distribution is not listed, follow the instructions specific to your package manager.
3. Install Git. To install manually, go here.
   • In Gentoo, emerge dev-vcs/git
   • In Archlinux, pacman -S git
   • In Ubuntu/Debian, apt-get install git
   • In Fedora, yum install git
     • If your distribution is not listed, follow the instructions specific to your package manager.
4. Open your shell and move to a convenient directory, then run git clone https://github.com/pahimar/Equivalent-Exchange-3.git. This will download the repository.
5. Create an empty directory for EE3 development. This directory is referenced as mcdev from now on. It can be where you cloned EE3, but it'll be a little messy.

Mac Prerequisites

1. Download and install the Java JDK here. Scroll down, accept the Oracle Binary Code License Agreement for Java SE, and download it. (Mac OS X comes with the JRE, but it is often Java 6, which does not always work.)
2. Apache Ant should already be installed on your computer. To check, go into Terminal, and type ant --version. It should return a version string. If you get a "command not found" error, it's not installed.
3. Download and install Github for Mac OSX (10.7+) here NOTE: This Github application is optional, you can use whatever you want.
   • Create an account.

• Scroll to the top of this page, login at the top-right, and then click Clone to Mac at the bottom of the right-hand toolbar.
• You should see Github flash and pahimar/Equivalent-Exchange-3 appear. (The local repository on Mac defaults to /Users/[username]/github/Equivalent-Exchange-3/. To change it, change the "Local Path")

5. Create an empty directory for EE3 development. This directory is referenced as mcdev from now on. It can be where you cloned EE3, but it'll be a little messy.

Setup MCP

NOTE: You may skip to "Setup EE3" if you want to let EE3 download and set up MCP for you. Simply run ant forge-install, then ant build.

1. Download the latest version of Forge source from here
2. Inside mcdev, unzip the zip file.
   • You should get a folder named "forge" inside "mcdev" containing the forge patches and licenses, etc.
3. Execute install.sh (Linux and Mac) or install.cmd (Windows), both found in mcdev\forge. On Linux you might have to chmod +x install.sh before you can execute it.
   • This will take some time, be patient.

Setup EE3

1. Inside mcdev, create a directory named source.
2. Move/clone Equivalent-Exchange-3 into source.
3. Right now, you should have a directory that looks something like:

---

mcdev
\-forge
	\-mcp
		\-jars
		\-CHANGELOG, etc.
	\-install.cmd
	\-install.sh
	\-MinecraftForge-Changelog.txt, etc.
\-source
	\-Equivalent-Exchange-3
		\-EE3's files (should have build.xml).

---

4. Inside Equivalent-Exchange-3, create a new file called environment.properties.
   • Open it up with any text editor, and type the following into it (change base_location to wherever you have "mcdev". NOTE: Paths must use forward slashes. All of the variables are changeable for your setup.):
     • base_location=C:/mcdev/
     • source_location=${base_location}/source/Equivalent-Exchange-3
     • mcp_location=${base_location}/forge/mcp
     • release_location=${base_location}/source/Equivalent-Exchange-3/Releases
   • You may also edit the build.properties to change the build string (mod_version and build_number), and the Minecraft and Forge version you are building for (forge_version is only used when running ant forge-install)
     • minecraft_version=1.6.4
     • forge_version=9.11.1.934
     • mod_version=pre2
     • build_number=1
5. Open up your OS's command line (Command Prompt in Windows, Terminal in Linux and Mac).
6. Navigate to mcdev\source\Equivalent-Exchange-3 by executing cd mcdev's location\source\Equivalent-Exchange-3.
7. Execute ant build. (If you want EE3 to setup Forge, run ant forge-install first.) This will generally take around 5-15 minutes, depending on your computer. If you've done everything right, BUILD SUCCESSFUL is displayed after it finishes.
   • If you see BUILD FAILED, check the error output (it should be right around BUILD FAILED), fix everything (if possible), and try again.
8. Go to mcdev\source\Equivalent-Exchange-3\Releases\MC 1.6.4\pre2.
   • You should see a .jar file named ee3-universal-pre2.jar.
9. Copy the jar into your Minecraft mods folder, and play Minecraft (If you have Forge installed on your client).

Updating Your Repo (For Windows/Mac)

1. Check to see if pahimar updated EE3 since you last compiled. If he did, follow these instructions.
2. Open Github.
3. Double-click on pahimar/Equivalent-Exchange-3.
4. At the top, there is a button named Sync/Sync Branch (or Refreshing... if it's still checking).
5. Click Sync, and wait for it to finish.
6. Re-compile (or move it to mcdev\source then re-compile, depending on what you did.)

Updating Your Repo (For Linux)

1. Check to see if pahimar updated EE3 since you last compiled. If he did, follow these instructions.
2. Navigate to the repository location.
3. Run git pull in Terminal.
4. Re-compile (or move it to mcdev\source then re-compile, depending on what you did).
