Jenkins Artifactory plugin - grabbing latest artifacts

I could not get this to work at all if I was using "aql", but it works when using "pattern" to find the file(s). When "build" is specified it will grab that build's artifacts only, even if the repo you're pointing at has a bunch a similarly named files (the build metadata in Artifactory takes care of this I guess). Without specifying "build" it would grab all of the matching artifacts.

"build" should be in the build-name/build-number format, but you can leave off the number OR use LATEST in order to grab the latest successful build's artifacts (I tested this by creating a failed build).

Example to illustrate:
- This will download file3 to Dependencies/file3
- Removing "/LATEST" will also download only file3
- Removing the whole "build" line will download all 3 files

# Artifactory Repo: example-repo/  
# BuildName: example-build
#   example-repo/file1  (from build 1)   
#   example-repo/file2  (from build 2)   
#   example-repo/file3  (from build 3)

Download File Spec:
{
    "files": [
        {
            "pattern": "example-repo/file*",
            "target": "Dependencies/",
            "recursive": "false",
            "flat" : "true",
            "build" : "example-build/LATEST"
        }
    ]
 }

For more info, see the build keyword in JFrog File Specs document https://www.jfrog.com/confluence/display/RTF/Using+File+Specs

build [Optional]

If specified, only artifacts of the specified build are downloaded. The 'pattern' property is still taken into account when 'build' is specified. The property format is build-name/build-number. If the build number is not specified, or the keyword LATEST is used for the build number, then the latest published build number is used.
