Can not setup initial files

[mariosyian]

So I am trying to start my own Minecraft Mod as a personal project to also expand my Java portfolio.

 

This is what I have done so far (keep in mind I have tried this on both Windows and Linux with no luck):

Currently on Windows 10 Home Edition 64-bit

• I have downloaded Gradle version 4.9

PS D:\Users\xxxxxxx\mcMod\forge-1.15.2-31.1.0-mdk> gradle -v

Gradle 4.9

Kotlin DSL:   0.18.4
Kotlin:       1.2.41
Groovy:       2.4.12

JVM:          1.8.0_241 (Oracle Corporation 25.241-b07)
OS:           Windows 10 10.0 amd64

 

• and JDK1.8 specifically (as well as JRE1.8 but not referencing it somewhere) and have updated the PATH variable to point to them.

PS D:\Users\xxxxxxx\mcMod\forge-1.15.2-31.1.0-mdk> java -version

This is my error log when running gradlew.bat from a fresh extraction of forge-1.15.2-31.1.0-mdk root folder:

Any help or feedback is highly appreciated.

SetupDecompWorkspace isn't a thing anymore, with 1.13 the system got rewritten.

 

Try taking a look at one of these tutorials.

[mariosyian]

Though helpful and has provided me with some insight. My Gradle project still does not import into Eclipse.

I have seen this exception with too many people but no answer as to the cause or a solution.

[DaemonUmbra]

You need to use Java 8

[mariosyian]

As I have shown in my first output:

PS C:\WINDOWS\system32> java -version
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)

 

And in the Gradle import window, I make sure this is the case by forcing it to use the jdk1.8 (see attached image).

 

I also wanted to ask, in the provided tutorial about build.gradle configuration (ref: https://cadiboo.github.io/tutorials/1.15.1/forge/1.0-gradle-configuration/), when it is said to add a few blocks of text namely, the sourcesJar and the processResources tags, they do not specify where. Should they be added at the bottom of the code? 

 

Thank you for the continuous assistance.

 

[Ugdhar]

I believe you should be using the gradle wrapper, and not your local gradle installation.

No luck unfortunately

Sorry for long thread

Would you suggest creating a JAVA_HOME and JDK_HOME System variable?

[mariosyian]

I am sorry for late reply! It appear I have forgotten to submit my comment.

Still does not work. I had the JAVA_HOME variable from the beginning.

 

I will try uninstalling all other java versions and redo Path variable and will check-in again.
