I have some artifacts in Artifactory (OpenSource):
I can download an artifact from using jfrog CLI:
jfrog rt config --user=admin --password=**** --url=http://foo:8081/artifactory
jfrog rt download testproject/01_Develop/01_CI/HPCC-Package-70.zip --flat=true
How can I download the LATEST(highest number) artifact?
You can use the JFrog Cli search command.
The search command will return a list of paths which you can then sort using external tools such as jq.
