Greetings Laurent,

The snapshot of 5.4.0 you've pointed to is currently the oldest snapshot
version we're hosting, and will likely rotate off the server sometime
today. Here is what we have for cdm-core at the moment:

https://artifacts.unidata.ucar.edu/service/rest/repository/browse/unidata-all/edu/ucar/cdm-core/5.4.0-SNAPSHOT/

As of this morning, we're on 5.4.0-20200810.143105-2 for the cdm-core
artifact. Are you manually downloading the snapshot jars, or are you using
a build system like maven or gradle?

Around the beginning to mid-july timeframe, I upgraded our build system
from Gradle v3.5 to Gradle v6.5.1, and for a while we were producing bad
snapshots as well as checksum files that were incompatible with the version
of the Nexus artifacts server we use - in this case, the jar file you point
to contains the javadocs, as the -javadoc classifier was getting dropped by
the build.

Can you give the latest snapshot artifacts a try?

Cheers,

Sean
