Setup Java

The Java JDK is used to compile EE3.

1. 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
2. Windows: Set environment variables for the JDK.
   • 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_51 exactly as shown (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 EXACTLY AS SHOWN and click Ok. Make sure the location is correct; double-check just to make sure.
3. 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, either try the steps again or check the FAQ.

Setup Gradle

Gradle is used to execute the various build tasks when compiling EE3.

1. Download and install Gradle.
   • Windows/Mac download link. You only need the binaries, but choose whatever flavor you want.
     • Unzip the package and put it wherever you want, eg C:\Gradle.
   • 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/gradle-bin
     • Archlinux: pacman -S gradle
     • Ubuntu/Debian: apt-get install gradle
     • Fedora: Install Gradle manually from its website (see above), as Fedora ships a “broken” version of Gradle. Use yum install gradle only if you know what you’re doing.
2. Windows: Set environment variables for Gradle.
   • Go back to Environment Variables and then create a new system variable.
   • For Variable Name, input GRADLE_HOME.
   • For Variable Value, input something similar to C:\Gradle-1.11 exactly as shown (or wherever your Gradle installation is), and click Ok.
   • Scroll down to Path again, and append ;%GRADLE_HOME%\bin EXACTLY AS SHOWN and click Ok. Once again, double-check the location.
3. Open up your command line and run gradle. If it says “Welcome to Gradle [version].”, then you’re good to go. If not, either try the steps again or check the FAQ.

Setup Git

Git is used to clone EE3 and update your local copy.

1. 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.

Setup EE3

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

1. Open up your command line.
2. Navigate to a place where you want to download EE3’s source (eg C:\Github) by executing cd [folder location]. If choosing a location other than C:\Github, just remember that when following the instructions.
3. Execute git clone https://github.com/pahimar/Equivalent-Exchange-3.git. This will download EE3’s source into an Equivalent-Exchange-3 folder such as C:\Github\Equivalent-Exchange-3.
4. Right now, you should have a directory that looks something like:

Github
\-Equivalent-Exchange-3
	\-EE3's files (should have `build.gradle`)

Compile EE3

1. Execute gradle setupCiWorkspace in order to set up Forge and download the necessary libraries to build EE3. This might take some time, please be patient :watch:.
   • You will generally only have to do this when the Forge version in build.properties changes.
2. Execute gradle 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.
3. Navigate to C:\Github\Equivalent-Exchange-3\build\libs.
   • You should see a .jar file named EquivalentExchange3-x.y.z-#.jar, where x.y.z is the Minecraft version number and # is the mod version.
     • NOTE: null means that you are missing a build_number value in build.properties or that your CI environment is set up incorrectly-it is totally safe to ignore.
4. Copy the jar into your Minecraft mods folder, and you are done!

Updating Your Repository

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

1. Open up your command line.
2. Navigate to wherever you cloned EE3 in the console.
3. Make sure you have not made any changes to the local repository, or else there might be issues with Git.
   • If there are local changes, try reverting them to the status that they were when you last updated your repository by executing git reset HEAD --hard.
4. Execute git pull master. This pulls all commits from the official repository that do not yet exist on your local repository and updates it.
