Hi - I’m trying to deploy the basic HandheldAR template and run into the following issue (photo attached).
Specifically, the error is:
“Exception in thread “main” javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target”
I’m working on macOS High Sierra and have Apple’s version of Java (Download Java for OS X 2017-001).
I’ve tried manually adding the certificate for the gradle distribution page, but that doesn’t seem to solve it.
Hi, I am having the same issue. Did you ever resolve it?
