I am using this version of forge 10.13.4.1558

[HappyKiller1O1]

For one, you should be using 1.8, as 1.7.10 will be quite out of date in a few months.

 

Secondly, how did you setup your workspace?

[iceblu008]

Ok thank you will test when I get home. When decompiling should I use gradlew setupDecompWorkspace eclipse or graldew setupDevWorkspace eclipse

[iceblu008]

This is what I get when I try to decompile forge-1.8-11.14.4.1577 with gradlew setupDecompWorkspace eclipse

You need to set the JAVA_HOME environment variable to the path of your JDK, not your JRE.

[iceblu008]

I did I went to control panel-computer properties-advanced system settings-environmental variables-entered this in the path C:\Program Files\Java\jdk1.8.0_60\bin

 

what am I doing wrong?

 

I do have java jre 1.8.66 installed should I uninstall it?

 

thank you

Don't set it to the JDK's bin directory, set it to the JDK directory itself (C:\Program Files\Java\jdk1.8.0_60).

[iceblu008]

It still doesn't work, it says the same build failed message. I used C:\Program Files\Java\jdk1.8.0_60

 

What is JAVA_HOME and how do I point it to the jdk?

[iceblu008]

I found com.sun.tools.javac.Main here tools.jar\com\sun\tools\javac

[Choonster]

It still doesn't work, it says the same build failed message. I used C:\Program Files\Java\jdk1.8.0_60

 

What is JAVA_HOME and how do I point it to the jdk?

 

Do you have the JDK installed in that directory?

 

JAVA_HOME

is an environment variable that tells Gradle where to look for the Java compiler. You set it to the path of the JDK like you would any other environment variable.

[iceblu008]

Yes, but I don't have anything pertaining to the jre in environment variable. Should I?

[Choonster]

Yes, but I don't have anything pertaining to the jre in environment variable. Should I?

 

The JRE is irrelevant in this case, there's no need to have it any environment variable.

 

If

JAVA_HOME

is pointing to your JDK path and it's still not working, run

gradlew setupDecompWorkspace

again and post the new output.

[iceblu008]

Ok, I will but I have to do it tomorrow because I have to wake up early for school tomorrow. I appreciate your help very much.

 

Thanks

[iceblu008]

By searching JAVA_HOME there were a lot of posts woth this problem. I think I need to make a JAVA_HOME environment variable with my directory in it. I still have to test it though.

[iceblu008]

It worked I just had to create a new environment variable called JAVA_HOME with your location of java jdk
