Download files from Artifactory to Teamcity without retaining their full path - teamcity

Question

I am using
TeamCity Enterprise 2017.1.2 (build 46812)
Artifactory Professional 5.3.1 rev 50046
Teamcity has the Artifactory plug-in installed (ver 2.3.0)
The task is simple - download files from Artifactory to Teamcity build:
From Artifactory MyRepo/RootFolder/ProjectFolder/1.2.3/<files>
To TC %checkoutdir%/artifacts/<files>
The <files> part of the path contains both folders and files and I want to retain their structure.
The download spec json is:
{
"files": [
{
"pattern": "MyRepo/RootFolder/ProjectFolder/1.2.3/",
"target": "artifacts/"
}
]
}
However, the files get downloaded into a different location than I would expect:
Actual: artifacts/RootFolder/ProjectFolder/1.2.3/<files>
Expected: artifacts/<files>
The whole path from Artifactory gets appended after the target directory. How do I tell the plugin to only use the relative path of files after the specified root? I have tried fiddling about with wildcards, slashes etc, but nothing helped.
I had to create an extra build step where I manually move files to the structure I expect, but I would prefer not to have to do that.
WORKING ANSWER:
{
"files": [
{
"pattern": "MyRepo/RootFolder/ProjectFolder/1.2.3/(*)",
"target": "artifacts/{1}",
"flat": "true"
}
]
}

You can customize your target structure by using Placeholders in your File Specs as described here.
Placeholders allow you to capture a specific section of your File Spec "pattern" property value, and use it inside the "target" property value.
In your case, the download File Spec should look like this:
{
"files": [
{
"pattern": "MyRepo/RootFolder/ProjectFolder/1.2.3/(*)",
"target": "artifacts/{1}"
}
]
}
