How to update to a new version of minecraft?

[That_Martin_Guy 7]

I have want to update my mod from 1.11.2 to 1.12. I tried to change the minecraft version field in my build.gradle, but when I run

gradlew clean setupDecompWorkspace it fails and says the following:

* What went wrong:
Execution failed for task ':fixMcSources'.
> com.cloudbees.diff.PatchException: Cannot find hunk target

Here is my build.gradle.

 

I cannot give you the whole log. It is 42598 lines long and 1.9 mb big, and therefore cannot show it on any code sharing site I know of.

You need to update ForgeGradle to 2.3 to use Minecraft 1.12.

Do I need to update the mappings value? Didn't seem to work without it. Got the same error still.

 

New build.gradle

 

EDIT: And yes I did remove the .gradle folder

Yes, you'll almost certainly need to update to a 1.12 mappings version.

 

You can find the latest mappings on the MCPBot website.
