I was trying to make a mod for 1.10.2, and I followed all the instructions in the Forge README.txt, I have a working version of Java JDK 1.8.0_121, and IntelliJ shows all my files from the Forge MDK and says it imported Gradle with no problem.
But when I go to test the setup with the 'Minecraft Client', the option isn't even there, and the Gradle window looks like this:
From my understanding, there should be a lot of stuff in there, not just that one file.
When I try to refresh the Gradle window, I get this error:
"Could not create parent directory for lock file C:\Program Files\Java\jdk1.8.0_121\wrapper\dists\gradle-2.14-all\t7wfomcrmv8dmyii9c9waem8\gradle-2.14-all.zip.lck"
This happens with multiple version of IntelliJ, and also with Forge 1.12.2. This seems to be a problem with Android Studio, interestingly, but I haven't found any help for Forge, Minecraft or IntelliJ.
