Hello -

 

I've looked around but it appears most of the time this is assumed to actually work, yet it does not for me.

 

- Have JDK

- Have latest version(s) of forge:

- forge-1.8.8-11.15.0.1595-1.8.8-mdk

- Forge 2.0.2 (from SourceForge)

 

Running gradlew.bat setupDecompWorkspace

 

The error I'm receiving on 2.02 is:

Any assistance or pointers would be appreciated.

Version: JDK 1.7.0_60

 

Don't worry about the 2.0.2, then, that was me trying to find a newer version that worked. I'll just stick with 1.8.8.

 

So part of it seemed to fix itself after my ISP stopped being annoying.

 

The other part I had to fix with the method you posted. Perhaps this is a new thing for Windows 10? I'm not sure. Here's what all I had to do:

 

keytool -import -alias repo1.maven.org -file "C:\Program Files\Java\jdk1.7.0_60\jre\lib\security\maven1.cer" -keystore cacerts -storepass somepass

keytool -import -alias libraries.minecraft.net -file "C:\Program Files\Java\jdk1.7.0_60\jre\lib\security\minelib1.cer" -keystore cacerts -storepass somepass

keytool -import -alias georoot -file "C:\Program Files\Java\jdk1.7.0_60\jre\lib\security\geo1.cer" -keystore cacerts -storepass somepass

keytool -import -alias geointer -file "C:\Program Files\Java\jdk1.7.0_60\jre\lib\security\geo2.cer" -keystore cacerts -storepass somepass

 

(You can save there directly, just add yourself to the full control list for the folder.)

 

The certs referenced above can be procured from:

https://repo1.maven.org/ (First one)

https://libraries.minecraft.net/ (Last three; use the process here: http://docs.bvstools.com/home/ssl-documentation/exporting-certificate-authorities-cas-from-a-website )

 

I hope this helps someone in the future.
