[netcdfgroup] Gradle suddenly failing to find metadata

Gradle just started failing for us this week with the following. I can still 
view maven-metadata.xml in my browser, and it appears a new certificate was 
issued on 2026-05-11 (this past Monday), which seems like a contributing 
factor. Have any of you seen this? Any suggestions?

   > Could not resolve edu.ucar:netcdf4:4.6.+.
     Required by:
         project :XXX
      > Failed to list versions for edu.ucar:netcdf4.
         > Unable to load Maven meta-data from 
https://artifacts.unidata.ucar.edu/all/edu/ucar/netcdf4/maven-metadata.xml.
            > Could not GET 
'https://artifacts.unidata.ucar.edu/all/edu/ucar/netcdf4/maven-metadata.xml'.
               > Got SSL handshake exception during request. It might be caused 
by SSL misconfiguration
                  > PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to find 
valid certification path to requested target

The related build.gradle configuration is as follows:

    repositories {
...
maven {
    url = "https://artifacts.unidata.ucar.edu/all/";
}
    }
    dependencies {
...
implementation 'edu.ucar:netcdf4:4.6.+'
...
    }
