If you've encountered SSL certificate errors while trying to download Maven dependencies from GitHub Packages, you're not alone. The error typically looks something like this: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:unable to find valid certification path to requested target This happens because Java maintains its own truststore (cacerts file) that contains trusted SSL certificates. If GitHub's certificate isn't in your Java truststore, your build tool (Maven/Gradle) will refuse to connect.
