How do you port a mod from 1.7.10 to 1.6.4?

[wildbill]

I followed the same basic steps as 1.7.10.

 

I downloaded the recommended 1.6.4 src, placed it in a folder under Eclipse, but no gradlew was present, so I read the readme. It said to run the install.bat, but this is what I see:

 

 

C:\eclipse\forge-1_6_4>install

I tried this several times. This is the output after several tries. I'm doing this on Windows 7. Could not find any log, not sure what that means.

 

Any idea what is wrong?

 

Thanks.

I don't know why, but Forge 965 uses MCP.  Go get 964, which has Gradle.
