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.
jfrog rt s "testproject/01_Develop/01_CI/HPCC-Package-*.zip"
The search command will return a list of paths which you can then sort using external tools such as jq.
JFrog CLI recently started supporting 3 new options from many of the Artifactory commands: --sort-by --sort-order and --limit.
You can use these options to search, download, copy, move or delete the latest artifact created in Artifactory. For example, to download the latest file uploaded to the all-my-frogs folder in the my-local-repo repository, use the following command:
jfrog rt dl "my-local-repo/all-my-frogs/" --sort-by=created
--sort-order=desc --limit=1
