"PKIX path building failed" error when install Vaadin Eclipse Plug In


I got exception of “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” when I tried to install Vaadin Plug in from https://vaadin.com/eclipse. I wonder anybody can help me out?


This blog post could help you:

The installation could be using SourceForge, but I’m not sure. There are some changes to the SourceForge security and Oracle JDK isn’t compliant, at the bottom of the post there are instructions on how to resolve. Hopefully it works for you!
