Please note that JAR libraries will only be unregistered after query evalution if they are moved into the repo directory. If a library is copied into the lib directory, it will be added to the static classpath. In the given case, you could probably keep kotlin-stdlib-1.4.32.jar in the lib directory, but you’ll need to keep your development code in the repository (as described in the Wiki). It’s no problem, though, to directly modify the repo code (you don’t have to use REPO INSTALL or repo:install for that). If the problem persists, feel free to send me a little test.jar, I can then do further testing. Hope this helps, Christian On Fri, Apr 30, 2021 at 9:14 AM Reece Dunn <[email protected]> wrote: > > Hi Christian, > > I'm not seeing any exceptions in the console window, even when enabling the > debug setting.
