UPDATE 10/10/16: We now have an updated step-by-step Minecraft Install Page that you can find here techrocket.com/minecraft-install This page will be updated periodically as Forge gets updated.
- JDK 7 update 79
- Forge 1.7.10
- Latest Version of Eclipse
You will need a copy of Minecraft in order to create your mods. To get Minecraft visit https://minecraft.net/ and click Get Minecraft. Fill out the form to create an account. You will then have to buy it, and once that is complete you will be prompted to download it.
If you already bought, Minecraft click the Download it here link.
Next you will need to download JDK 7. **
Oracle has updated their page so Java 7 is not easily accessible. You can find it here.
Under the “Java SE Development Kit 7u79” download the executable that relates to your system. For example I have a 64x bit Mac computer so I would download that Mac OS X x64 version. NOTE: You have to accept Oracles License Agreement before downloading.
Next you will need to download Eclipse, which is an integrated development environment (IDE) used to develop Java code. You can download Eclipse from http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/neonr
You will download Eclipse IDE for Java Developers on the right you will see five links that will show your system and two possible options either 32 bit or 64 bit. Download the version that corresponds to your system. The current version of Eclipse as of this post is Eclipse Neon.
You will then be directed to the downloads page where you can download the provided mirror link. The link will be different sometimes so don’t worry, select the link and your download will begin automatically.
EDIT NOTE: When visiting the Minecraft Forge website DO NOT click on the ads or any other link that redirects you away from their site. You should be following the Minecraft Forge Installation instructions exactly. Clicking on any suspicious links leaves your computer vulnerable to viruses.
Now it’s time to download the famous Forge which is the key to modding in Minecraft. Navigate to http://files.minecraftforge.net/ and you will see multiple options.
We will be using Forge version 1.7.10 (recommended) select on the link that reads (Src) and the download will automatically begin. when it’s done drag the Forge directory to your Desktop.
Time to configure forge! Open your terminal/cmd and change the directory to the Forge directory that should be on your Desktop like so.
The easiest way to change the directory is to enter the command cd and then drag the forge directory from your desktop to the terminal/cmd.
Once we are in the designated directory enter the following command to install Forge. There will be different commands based on your system (Windows or Mac)
This will take several minutes, but will prompt you when the build is successful
After the first command is done, we now need to configure Eclipse. Enter the following command, this one should be a little faster.
Once that builds successfully you are ready for Minecraft Modding!
If you are having errors in regards to the JAVA_ENVIRONMENT variables follow these instructions
Enter this command in the cmd window:
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_79
You Are Done! Now You Can Follow The Tutorial And Make Some Mods!

My mac computer says my thing is "OUT OF MEMORY". Is there a way to fix this? Please help!

Is there any file that i can download to sustitute the .minecraft?

Not an expert on this, but what works 70% of the time is restarting your machine or Minecraft. Try checking your code and posting it here.

Are you talking about having a problem running minecraft or getting forge running?
If you installed the forge directory on your desktop, you should open eclipse to
forge > eclipse
As for the out of memory situation, I've done a bit of research and found that one case that causes the problem is having the 32bit version of java when you should have the 64bit version, or vice versa.
Incidentally, I also found this:
Hope that helps,

Thanks! The only thing is, its JAVA thats running out of memory. When I try to recompile minecraft, it says "OUT OF MEMORY". I have the right version. Im not sure it is a bug, because on my windows itworks
tamasaurusrex — 2014-09-25T19:57:42-04:00 — #7
It's not uncommon for multi-platform software to be fine on one operating system but not on another. This is due to having multiple dev teams working on two different sides of the same project, but occasionally communication is missed somewhere. Can you post the exact error message that you're getting? I've never seen this particular problem before, but I will absolutely try to help you solve it.
ctywarrior — 2014-09-26T21:22:11-04:00 — #8
it doesn't work anymore. I try to send the error message but it now says that the repack minecraft it "§4SKIPPER§r". Sorry

Can I use IntelliJ IDEA with forge instead of Eclipse? I like IDEA better.
tamasaurusrex — 2014-09-27T00:16:27-04:00 — #10
You shouldn't need to recomp minecraft during the installation process. Are you trying to publish a mod?
ctywarrior — 2014-10-04T09:27:30-04:00 — #11
NO, it says that it doesn't work, and when I open eclipse, there is nothing in the "mine craft" folder.

Greetings ATL347 here,
I'm having trouble getting Minecraft to launch from Eclipse. I've followed the instructions from the online course Getting Started with Minecraft Mods and have gotten through the download and installation of:
Eclipse Standard 4.4
Java Dev Kit 8u20
I'm on a MacBook Pro running 10.9.5 w/ 4GB of RAM
The error I get is when I try and run My First Mod after the tutorial. Here's what Eclipse says:
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

I've read through the forums and saw happyhappy08 was able to get it work by installing Java JDK 7u67. I tried that but I still get the same error.
debug — 2014-10-13T12:26:28-04:00 — #13
The problem is that you have Java 8 installed. Java 8 will not work. You have to run eclipse using Java 7.

This topic is now pinned globally. It will appear at the top of its category and all topic lists until it is unpinned by staff for everyone, or by individual users for themselves.

It took some time but my dad was able to research and resolve my issue. I can finally Mod!!
Here's what my dad did for others who might have the same issue:
(I'm on a MacBook Pro running 10.9.5 w/ 4GB of RAM)
Completely Unistall Java JDK 8u20
1) In the Finder menu bar under the Go heading select the Go to Folder sub heading
2) Type /Library/java into the Go to the folder: window and [click] the Go button
3) Hold [control] & [click] the JavaVirtualMachines folder and select the Move to Trash sub heading
4) Go back to the Go to Folder sub heading
5) Type /Library/Internet Plug-Ins/JavaAppletPlugin.plugin into the Go to the folder: window and [click] the Go button
6) 3) Hold [control] & [click] the JavaAppletPlugin.plugin folder and select the Move to Trash sub heading
Install Java jdk-7u71-macosx-x64.dmg
1) Open an Internet Browser window (e.g. Safari, Chrome, Firefox. etc)
2) Follow this link: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html to the Java SE Development Kit 7 Downloads page
3) [click] the radio button to Accept License Agreement
4) [click] the jdk-7u71-macosx-x64.dmg link under the Download column
5) Once the software is downloaded [double-click] the jdk-7u71-macosx-x64.dmg to open
6) [double-click] JDK 7 Update 71.pkg to install
After that Eclipse ran fine without any errors - yeah!
Thanks dad & dEbug, I can finally Mod

Awesome! I'm glad I can help!
davidee2003 — 2014-10-22T16:34:12-04:00 — #19
everytime i try to download forge in the terminal its says failed with an exception of "recompminecraft"!!!!
debug — 2014-10-22T18:16:19-04:00 — #20
Can you post an screen shot of the error you're receiving. It will be better for us to dEbug your issue.
debug — 2014-10-22T18:40:29-04:00 — #21
In the mean time @Davidee2003 can you do me a favor and in your terminal window run this command
java -version and tell me the version of java you currently have installed?
youpster — 2014-10-28T21:10:13-04:00 — #22
You are a lifesaver! Anyone who has problems can follow ATL3471
Thanks a lot!
