These instructions are for Windows 8.x. They should work with relevant modifications for other OSes, but I didn't test it, since I did not have this issue under Linux. I'm going to try and put all of the "solutions" in one place, since it took me forever to track them down, and even then, they did not work for me. I had to step through the code in the debugger to determine that I needed to add /virtual/legacy to one of the proposed solutions: I was able to get this working by adding --assetsDir "C:/Users/Oli_Gophrenos/.gradle/caches/minecraft/assets/virtual/legacy" to the Run -> Run Configurations ... -> Arguments [Tab] -> Program arguments [Text Field]. For me, this all blew up after trying to move my project in Eclipse (Right-click project -> refactor -> move), eclipse crashed leaving a mess. I decided to just pick the files from the two locations and start over. Staring over resulted in no sounds and no application icon. Everything else seemed to work just fine. The salient errors in the Eclipse console are: And things like: I generally believe that whenever possible, use what you're "supposed" to use, and don't make edits. So my recommendation is that if re-running gradlew works for you, you might want to do it. BEFORE you do, back up your files. http://www.minecraftforge.net/forum/index.php/topic,12392.0.html suggested . You can give it a try, but don't hold your breath. As suggested by http://www.minecraftforge.net/forum/index.php/topic,15189.msg77124.html#msg77124 try running each of these in turn in the directory where you extracted the forge source files: gradlew.bat setupDecompWorkspace gradlew.bat eclipse gradlew.bat --refresh-dependencies eclipse If that does not work (which it didn't for me) you can try cleaning first: gradlew.bat clean gradlew.bat cleanEclipse and then running the stuff above again. If that does not work, you can try blowing-away and re-extracting forge-1.7.2-10.12.2.1121-src. None of that worked for me. Then there are https://github.com/MinecraftForge/ForgeGradle/issues/103 and http://www.minecraftforge.net/forum/index.php/topic,20798.msg105115.html#msg105115 : --assetIndex 1.7.2 --assetsDir "C:\Users\Oli_Gophrenos\.gradle\caches\minecraft\assets" OR --assetsDir "C:/Users/Oli_Gophrenos/.gradle/caches/minecraft/assets/virtual/legacy" Whichever works for you; just replace "Oli_Gophrenos" with your home folder name usually your windows username. Note that the quotes are optional if you don't have spaces in your path (e.g., your username is "Oli Gophrenos" in stead of "Oli_Gophrenos"). Also, the "--assetIndex 1.7.2" parameter seemed to change nothing for me. You can also try changing the Run -> Run Configurations -> Arguments -> Working directory to ${workspace_loc:Minecraft/eclipse} , but again, although it seemed to help some users, it did nothing for me. You can try http://www.minecraftforge.net/forum/index.php/topic,14256.0.html if you are NOT using a current version of Forge. I think the suggestion is to copy the files in %appData%\Roaming\.minecraft\assets into your C:\Users\Oli_Gophrenos\.gradle\caches\minecraft directory. That's all I remember/thought worth mentioning.
