com.cloudbees.diff.PatchException: Cannot find hunk target error


Recommended Posts

Hello everyone, I tried to post this on the minecraft forums but did not get any responses. I don't think there are many coders there :)

 

Specs

Both computers Win 7 x64

JDK 9

JRE 9 (also tried 1.8.0.144)

Eclipse Oxygen (it opens just fine)

Forge 1.12.1-14.22.1.2485

Added path to enviornment vars

Minecraft 1.12.2

 

My son and I are long time Minecrafters, we are no slouch with tech stuff having done some Unity development together as well as Robox. We are trying to create a MOD and running into the following error:

 

Execution failed for task ':fixMcSources'.

> com.cloudbees.diff.PatchException: Cannot find hunk target

 

edit: The forge command we are using is:

 

gradlew setupDecompWorkspace eclipse


 

We have scoured the internet for other forum posts about this error and tried various solutions, no progress. I did however find this thread post right here:

It says that Forge doesn't support JDK 9.0, is this true? Thanks for any help you can throw our way! 

 

Here is the log:

It is just 

gradlew setupDecompWorkspace

And yes to my knowledge java 9 is not yet supported.

 

Also Ive heard gradle was down earlier but it seems to work now so i would try it again.

I am also having this issue but for me switching to JDK 8 had absolutely no effect what so ever, and the same error occurred at the same % of deof.

Yea my son and I tried this last night too, we have an older version of JDK but no dice. I wonder if JDK9 left something behind in the registry when we uninstalled it? I will have to try it on another computer at work, maybe something that has never had JDK9 install. I will get back to you guys. 

 

So who recently WAS ABLE to install Forge and make a minecraft mod? We want to make the easiest mod to start ... a "hello world" mod or something haha... can't even do that. 

 

Thanks for the responses ...

Thank you, that worked. Here is what we did to get the mods working

 

Windows 7 64x

Date today is Nov 5, 2017

Minecraft Forge 1.12.2

 

1. Uninstall JRE and JDK 9 (I also like to Cclean.exe the registry and reboot but prob not needed)

2. Install Java 8 Update 151 (Runtime)

3. Install Java SE Development Kit 8 Update 151

4a. Add C:\Program Files\Java\jre1.8.0_15\bin to PATH enviornment variable

4b. Add C:\Program Files\Java\jdk1.8.0_151\bin to PATH enviornment variable

4c. Add C:\Program FIles\Java\jre1.8.0_151 to JAVA_HOME enviornment variable (create it if not present)

5. WIndows > Run > CMD.exe and navigate to your minecraft mod folder

6. Run "gradlew cleanCache"

7. Run "gradlew setupDecompWorkspace && gradlew eclipse

(If you're planning to use Eclipse, you should, Eclipse IDE rocks and its open source)

 

At the end, it should say "BUILD SUCCESSFUL" at the end. I'm not sure if step 4 or 7 is needed. But this worked for me. 

 

Thank you everyone! I am continuing to build my first mod with my son. He is ahead of me and has run into a few problems. I'm trying to catch up to see if we can resolve together. Social media rocks, hope this helps out someone else.

Ok ran into a slight roadblock when opening Eclipse for the first time. 
I downloaded Eclipse IDE for Java Developers

 

It couldn't find JRE or JDK Java Virtual Machine

 

So I changed the eclipse.ini file to point to the JRE \bin folder as so:

-vm
C:\Program Files\Java\jre1.8.0_151\bin
--C:\Program Files\Java\jre1.8.0_144\bin <--- this is commented out and ignored 
--C:\Program Files\Java\jre-9\bin  <--- this is commented out and ignored 

 

The eclipse.ini folder was located in the eclipse folder found in c:\users, not program files.

On my computer, eclipse.ini was found in this folder

C:\Users\Administrator\eclipse\java-oxygen\eclipse
