[1.12.2] [OS X] Certificate error when running setupDecompWorkspace

[Kinniken]

Hi all,

I was recently trying to setup my mod's dev environnement again, and the same build script that worked just fine last time I used it a few months ago is now failing with the error below:

 

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':forgeGradleUserDevPackage'.
> Could not resolve net.minecraftforge:forge:1.12.2-14.23.5.2768.

            > sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

 

The URL given works fine when tested in Chrome.

 

Anybody has any idea about this issue? Something linked to a system update maybe?

 

Thanks

If anybody gets the same error, it's due to older versions of Java 8 not supporting the Let's Encrypt certificates used by minecraftforge.net: https://stackoverflow.com/questions/34110426/does-java-support-lets-encrypt-certificates

 

The solution is simply to install an up-to-date JDK, at least Java 8_101.

I made an account just to respond to this.  I had been looking around the internet for a few hours trying to figure out what was going wrong until I found this.  Thanks so much!

No problems, glad to have helped! It was a bit of a tricky issue... not sure I would have figured it out without a vague memory of having read something on Java not supporting Let's Encrypt some months back.

Not sure if this is related, but I was having similar troubles with setupDecompWorkspace yesterday,  and updating my JDK fixed it.

Edit: probably should have read this post more lol. Still, you might need to take extra steps, which are detailed in the above thread.

I had the same problem. Can't for the life of me find the thread I had opened for this. So I don't know who from the forge guys exactly had answered.

 

The fix is to update the JDK (not only the JRE, which is the default when updating). Go to Oracle, download the latest JDK and install. Then try to run gradlew again. This should do the trick.

 

Edit: answered a quarter of a year old thread ... sorry ... but I had exactly this problem just a few days back ...
