watch for new files on FTP Folder

[b2un0]

we are try to using the following config to trigger a build, if some file is placed in one of the two FOLDER_* directories.

But nothing happens, any idea whats wrong?

properties([
        disableConcurrentBuilds(),
        buildDiscarder(logRotator(numToKeepStr: '30')),
        pipelineTriggers([
                URLTrigger(
                        cronTabSpec: 'H/5 09-18 * * 1-5',
                        entries: [
                                URLTriggerEntry(
                                        url: "ftp://${ftpUrl}/FOLDER_1/",
                                        username: ftpUser,
                                        password: ftpPw,
                                        contentTypes: [
                                                MD5Sum()
                                        ]
                                ),
                                URLTriggerEntry(
                                        url: "ftp://${ftpUrl}/FOLDER_2/",
                                        username: ftpUser,
                                        password: ftpPw,
                                        contentTypes: [
                                                MD5Sum()
                                        ]
                                )
                        ]
                )
        ])
])

the logs are here:

Hi @b2un0 - from a cursory look, it seems as though the trigger only currently looks at file contents, rather than directory contents (I'd need to set up an FTP server and experiment to prove this). Looking at the underlying client that's used for the connection, it should be possible to develop what you're looking for, but doesn't seem to be the case that it does it at the moment.

I'll add this to the wishlist.
