You can find them here:
When you hone in on the specific jars (consol2 and mu2consol for v3.0.0.20240822), you can download them via an icon in the top right.
You may have to use an incognito window and you may have to agree to keep the download due to the http connection.
If you are trying to download them as part of the local install using maven, it should work as is. Maybe artifactory was down when you tried last, if that was the case. That's also another way to get all of the jars you need. You can clone the Reference C-CDA Validator (
https://github.com/onc-healthit/reference-ccda-validator/) and its dependencies (code validator and content validator) from Github and the run a Maven install and it will download the jars to your .m2 repo. You can then grab them from there if you need them.
