Version 85 & 84 on Jenkins, Fails to build with the command arguments of "--rev 1.8.8", No issues on Version 83 or later. Log is attached 

The error occurs when it attempts to build the final mapped jar: work/mapped.ba9a3cce.jar does not exist, creating (please wait)!

Any more information feel free to ask. I work on the Pterodactyl Panel project, and our script uses the latest build tools to build the server jar files, so this is kinda hindering people make a 1.8.8 Spigot server.

Note: First issue, not sure if it's correct. Sorry in advance
