MoltenCode

Hi, I'm a new guy in modding and I want to install the Forge to modding. First : I'm on mac, and I'm French so sorry for my english I went on the Forge site and I follow the instruction on the Forge documentation (http://mcforge.readthedocs.io/en/latest/gettingstarted/) to start in modding. So I download the mdk version of Forge, I extract it on a folder, open a command prompt and with a bunch of cd go to the file. Here comes my problem, I use the commande ./gradlew setupDecompWorkspace but that doesn't work... The error message is Exception in thread "main" java.io.FileNotFoundException: /Users/TD/.gradle/wrapper/dists/gradle-2.14-bin/76oc0mnc3ieqtsukq90mp0rxk/gradle-2.14-bin.zip.lck (No such file or directory) I don't understand why so if you can help me thank you in advance
