Jenkins Artifactory Plugin not working with recent Artifactory version - jenkins

Question

We have the following steps in our Jenkinsfile (trying to upload artifacts to our Artifactory server):
def server = script.Artifactory.server("our-artifactory-server-id")
def uploadSpec = """{
"files": [
{
"pattern": "${sourcePath}",
"target": "${targetPath}"
}
]
}"""
server.upload(uploadSpec)
This used to work until we updated to a newer version of Artifactory. Ever since the update, we get the following error when running the build job:
java.io.IOException: Failed to deploy file. Status code: 400

Finished: FAILURE
Some background regarding our setup:
Jenkins version 2.69
Artifactory version 5.8.4
Artifactory plugin version 2.14.0
the error started to appear with a recent update of Artifactory
the Artifactory log shows no output for the error
we are sitting behind a proxy, but no_proxy is set correctly, at least we can curl https://... to our Artifactory host
we have self-signed certificates for Artifactory, but they should be properly added to the java truststore and the system truststore, since we can open URLs in java apps as well as with curl without any issues.
Any idea how we could debug this issue?

Answer 1

I had a very similar issue and found the solution in the configuration of the Artifactory-Jenkins plugin (manage jenkins --> configure system --> artifactory).
What I did was changing the Artifactory server URL from:
https://<artifactorydomain.com>
to the new URL (adding the /artifactory):
https://<artifactorydomain.com>/artifactory
Hope this helps.
