"gradlew setupDecompWorkspace" Build Failed. "Java Heap Space" Error

[Grosso10]

I execute "gradlew setupDecompWorkspace"

and it says: (After 20 min or so)

Failure: Build Failed.

 

Execution failed for task ':decompileMC'

>Java Heap Space

Build Failed.

 

Can anyone help me?

 

I have already tried gradlew --refresh-dependencies

and gradlew clean

Hi,

Java need more memory (2 gb is recommanded to decompile MC 1.8.8 )

[hal1024]

I have the same error.  How do I increase the Java memory?

[Grosso10]

So, what should I write in the command line to increase my memory?

 

gradlew setupDecompWorkspace -Dorg.gradle.jvmargs ?

gradlew setupDecompWorkspace -d64 ?

 

Thanks!

yup same error

but the mine stuck exactly in 

> Building 56% > :decompileMc

 

at he end says something about it could be faster if you uses other dont remember whath version of graddle of something

You can also edit the gradlew.bat or gradlew file directly.

 

Change the DEFAULT_JVM_OPTS="" line to DEFAULT_JVM_OPTS="-Xmx1024m"

 

If you still get the error, change 1024 to 2048.

Good days

 

do you refer to the line number 12 from the gradlew.bat file in the forge main folder,

 

@if "%DEBUG%" == "" @echo off
@rem ##########################################################################
@rem
@rem  Gradle startup script for Windows
@rem
@rem ##########################################################################

@rem Set local scope for the variables with windows NT shell
if "%OS%"=="Windows_NT" setlocal

@rem Add default JVM options here. You can also use JAVA_OPTS and GRADLE_OPTS to pass JVM options to this script.
set DEFAULT_JVM_OPTS="-Xmx2048m"

 

 

it dont works for my, i alredy try at 1024 and 2048 whithout succes

 

 

this is the console output

is anything else to do to  fix this ??

thanks for reading

Leave the gradlew.bat file alone. Then just make sure you have JDK installed, the newest one and it will work.

[DestroyerTheWorm]

Actually, do change the gradlew arguments. I had the same issue, and, in being in the best spot possible for wifi, got it to work with 1020m. If 2040 does not work, plug in to your Ethernet cable and allot 4000m in the bat file. DecompileMc is a big task, and I think requires internet. Heap size is how much memory/power you allot to whatever you want to do. I would reccomend not going over 4g of heap size, as then things get quite messy with maximum heap size allotments.

enable seeing file extensions.

 

go to where you extracted the zip.

 

make a text named

gradle.properties

 

inside put

org.gradle.jvmargs=-Xmx1300M

 

you now have 1.3gb allocated

 

you don't really need more than this...

 

gradlew clean is for when you get your .jar out of the build lib.

It will erase and clean your builds but not affect the code.

So you get a clean build every time. (like if you were going from one project to another)

you should run gradlew clean before building the 2nd src so that the 2nd build does not obtain files from your previous one.

 

need the most up to date java and java jdk

along with elcipse. (neons what i got right now)

 

before running gradlew build though I highly recommend opening your gradle.build and put this at the end after the last

}

sourceCompatibility = 1.8

targetCompatibility = 1.8

 

 

this will target java 8 on setup.

and your eclipse will thank you later.
