Thanks for the help - after looking at my system, I found an old NVidia Codeworks for Android installation that had installed Gradle and the outdated JDK, so a quick uninstall and restart later, and it looks like everything is going to be ok

Sorry, I really do appreciate your response to my thread, so if I've misinterpreted what you were asking, it's my inexperience at fault. I did gradlew -v and got this: ------------------------------------------------------------ Gradle 4.9 ------------------------------------------------------------ Build time: 2018-07-16 08:14:03 UTC Revision: efcf8c1cf533b03c70f394f270f46a174c738efc Kotlin DSL: 0.18.4 Kotlin: 1.2.41 Groovy: 2.4.12 Ant: Apache Ant(TM) version 1.9.11 compiled on March 23 2018 JVM: 1.8.0_77 (Oracle Corporation 25.77-b03) OS: Windows 10 10.0 amd64

I installed JDK 8u221 from the Oracle website. Maybe I should just uninstall Java and Eclipse, and then restart from scratch?

OK, now my simple brain is very confused - I am only trying to use files from the Forge MDK that I downloaded, forge-1.14.4-28.1.40-mdk

OK, so I'm using 8u221, which is the latest JDK 8 version from the Oracle website. Do you, therefore, mean that I should be using Java SE 11 kit or SE 12 kit?

I'm trying to start my first foray into making a Minecraft mod. So far, I have followed guidelines and installed Eclipse (version 2019-09 R 4.13.0), installed the Java SDK (Version 8 update 221, build 1.8.0_221-b11) (downloaded and unzipped the forge-1.14.4-28.1.40-mdk into a folder, and then opened a powershell into that folder and tried to start the gradle commands. At the first stage, gradlew setupDecompWorkspace, I get an error with gradle being unable to get a resource. Stack trace below. Any help here very much appreciated (nb, same error happens with gradlew eclipse, it cannot get the resource for some reason). I've tried turning my AV firewall off during the process, but no difference. For reference, I'm running Windows 10.
