04/04/2023, 7:48 PMIn server.json, I'm confused as to what app.libDirs is doing. If I use this.javaSettings, my jar works fine placed into a /jars folder in my project, but if I use app.libDirs then it complains about missing dependencies that are installed in ACF by default (like commons-logging.jar). Is that expected behavior?

04/04/2023, 7:52 PMit would be more convenient to just use libDirs instead of javaSettings due to how this project is structured, so that's a bummer, but thanks for the explanation

04/04/2023, 7:53 PMThough, for what it's worth, it's a little sloppy to depend on that jar in the CF core. You can add your own version of commons-logging alongside your custom jar. Just keep in mind, if you include a different version of commons-logging as ACF uses, that may also cause different errors. Welcome to java classloader hell 🙂
