If you use LUCEE_EXTENSIONS without specifying a version, Lucee asks for the latest version available.
Since 7 introduces some changes which mean the latest versions of the extensions won’t work with 5 or 6, this can lead to some annoying failures.
I rolled out support for querying for the latest extension version, by coreVersion (aka only extensions which are supported by your current Lucee version) to the update provider a few days ago.
eh wut? i.e. I’m on Lucee 6, don’t give me extensions which require Lucee 7
We discovered today, that Lucee wasn’t passing this coreVersion thru when downloading via LUCEE_EXTENSIONS. Thanks to @ghedwards for letting me know something wasn’t working!
This has been fixed in 6.2.2.12-SNAPSHOT and 5.4.8.0-SNAPSHOT (LTS)
Generally speaking, it’s a good idea to pin (use exact) your extension versions, as described in the ticket below.
