BUILD FAILED in 3s

  I am new in java scripting so I have no clue where my Error is. I try to make my own mod for Minecraft with eclipse and forge. In the installation manuel the first step is to run cmd with the command "gradlew genEclipseRuns", but after that it crashes and says " Build failed". I already found some possible solution for that problem in this forum but none of them had worked for me.

-I installed Java jdk1.8.0_212 and jre1.8.0_212

-I am using Minecraft 1.14.3 and Forge 1.14.3

-I am using Windows 8.1 Pro 2013 64bit and also java is 64bit

-RAM is high enough "org.gradle.jvmargs=-Xmx3G"

 

Can someone help me please?

You're using an outdated version of Java.

Gradle is using an old version of Java.

Thank you very much for your reply, it worked, my enviromental varibles were wrong, but know it works.

 

But I have still an issue, after setting everything up the "MDKexample" (the template project) is missing.

I tried to delete everthing and to reset everthing but that file is still missing.

-i used the command "gradlew genEclipseRuns"

-after that i also used the command "gradlew eclipse"

-both were successfull

-than I started eclipse, and selected the main folder "MyMod" --> no files

-than i tried to search for the file manualy --> no files

 

i would be very thankfull for another advice

 

ps.I probably should make a new topic for that question
