I am using a gradle dependency and have been for the past 12 months. All of a sudden today, it can not resolve.

I have tried changing the version, cleaning my build, reinstalling Android SDK's etc. but all to no avail.

I was hoping someone could help me in resolving this issue. The error is below:

I have figured out the issue.

The issue was that the ponent author changed their IP address and failed to inform the munity.

Gradle keeps a cache of plugins and I had to clear the cache in order to make gradle recognise the new IP address. To do this I did the following:

In Android Studio:

1. File > Invalidate Caches / Restart...
2. Invalidate and Restart

In Android Terminal (OSX):

./gradlew cleanBuildCache

In Android Terminal (Windows):

gradlew cleanBuildCache

This is going to sound weird, but you should check that your system clock is set correctly, including the proper time zone.

If your system time is correct, you might need to nuke and re-install your JVM.

Your build is failing because Gradle can't reach the artifact repository. When it tries to connect, it's throwing this error:

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

That's Gradle telling you that the TLS handshake between Gradle and the artifact repository is failing.

There's a few reasons this could happen:

1. Somehow your trust store got zapped so the JVM doesn't recognized any SSL certs, including CA-signed ones.
2. Your system time is so bonkered that the validation routine thinks the site's SSL certificate is expired, or hasn't taken effect yet.
3. You're behind a TLS-aware proxy but you don't have the proxy's cert in your trust store.
4. The repo's SSL certificates are in fact hosed (in which case it'd be down for everyone, not just you)

You can rule out most of these by pointing your web browser at the repository download URL shown in the error. If the file downloads, you know it's not your system time or the server's SSL certificates.
