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

[todanielchow]

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 ...

gradlew cleanCache

For me using both JDK version 8 AND Runtime version 8 solved the problem.

[todanielchow]

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
