FG 2.3 setupCiWorkspace Failure

Hello all,

It seems that the recent commits to ForgeGradle 2.3 has broken the setupCiWorkspace task:

$ ./gradlew setupCiWorkspace

This mapping 'snapshot_20171003' was designed for MC 1.12! Use at your own peril.

> There is a binary discrepency between the expected input class net.minecraft.client.renderer.entity.layers.LayerHeldItem (ccc) and the actual class. Checksum on disk is da0f6687, in patch 5f7c661a. Things are probably about to go very wrong. Did you put something into the jar file?

As shown in the log, the ForgeGradle revision was 5ce6d6f. The last revision I used that worked normally is 7764e3e.

I was able to reproduce this problem with both Gradle 2.14 and 4.9 (Gradle wrapper was used in both cases), on OpenJDK 1.8.0_222 64-bit Server VM.

The setupDecompWorkspace task works fine. I understand it if anyone suggests using that task instead, but I do hope that the setupCiWorkspace task could work as well because I prefer to use it in the CI build environment of my mod project.

How can this issue be fixed?

Thank you!
