[Contributing](https://github.com/pahimar/Equivalent-Exchange-3#contributing) - For those that want to help out. ### Compiling Equivalent Exchange 3 IMPORTANT: Please report any issues you have, there might be some problems with the documentation! *** #### 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](http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html). Scroll down, accept the `Oracle Binary Code License Agreement for Java SE`, and download the one pertaining to your OS (necessary for MCP). * 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 (x86)\Java\jdk1.7.0_25` 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 `;C:\Program Files (x86)\Java\jdk1.7.0_25\bin` (or your Java JDK installation directory\bin), and click `Ok`. 3. Download Apache Ant [here](http://ant.apache.org). * Unzip the files anywhere you want, eg `C:\Program Files (x86)\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-1.9.0` (or your Ant directory\apache-ant-1.9.0). * Scroll down to `Path`, and double-click on it. * Append `;C:\Ant\apache-ant-1.9.0\bin` exactly as shown to the end (or your Ant directory\apache-ant-1.9.0\bin). 4. Download and install Github [here](http://windows.github.com/) (Windows) or [here](http://mac.github.com/) (Mac OS X 10.7+). For Linux, you can use a different Git application. NOTE: Github For Windows/Mac is OPTIONAL. You can use your own Git application. * Create an account. * Scroll to the top of this page, login at the top-right, and then click `Clone to Windows/Mac` 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 refernced as `mcdev` from now on. It can be where you cloned EE3, but it'll be a little messy. #### Setup MCP 1. Download the latest version of MCP from [here] (http://mcp.ocean-labs.de/download.php?list.2), e.g. mcp751.zip. 2. Inside `mcdev`, create a directory named `mcp` and unzip the MCP .zip file into it. * To verify, check if a file named `CHANGELOG` exists inside `mcp`. 3. Download the latest Forge **source** for Minecraft 1.5.1/1.5.2 and unzip it into `mcp`. You need at least Forge 7.7.1.500 (Forge 7.8.0.684 if using 1.5.2), the best way is to get it from [here] (http://files.minecraftforge.net/). * To verify, check if a application named `install.sh` exists. 4. Execute `install.sh` (Linux and Mac) or `install.cmd` (Windows), both found in `mcdev\mcp\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 \-mcp \-complicated mcp stuff (should have CHANGELOG). \-forge \-jars \-source \-Equivalent-Exchange-3 \-EE3's files (should have build.xml). *** 4. Inside `Equivalent-Exchange-3`, create a new file called `build.properties`. * Open it up with any text editor, and type into it the following (fully customizable except for `dir.development`): * `dir.development=../../` * `dir.release=Releases` * `release.minecraft.version=1.5.2` * `release.mod.version=pre2` 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`. 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, and try again. 8. Go to `mcdev\source\Equivalent-Exchange-3\Releases\1.5.2\pre2`. * You should see a `.jar` file named `ee3-universal-pre2.jar`. 9. Copy the jar into your Minecraft mods folder, and play Minecraft! #### 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.) ###Contributing *** #### Submitting a PR So you found a bug in pahimar's code? Think you can make it more efficient? Want to help in general? Great! 1. **IMPORTANT: PAHIMAR DOES *NOT* WANT ANY** `build.xml` **CHANGES, UNLESS it fixes up something broken** (See [Pull Request #90](https://github.com/pahimar/Equivalent-Exchange-3/pull/90)). 2.
