Hi Gaetano, > I created a small example that requires my library
Thanks for the working example. I did some digging, and here is what I discovered: - Vanilla ImageJ1 does not have a "jars/" folder, so unpacking your JAR there would not work in that scenario. - Having an unpacked directory structure in "plugins/" _does_ work, though. - The reason it doesn't work in ImageJ2 is because ImageJ2 recursively adds all subdirectories of all classpath directory elements to the effective classpath of the plugin class loader. - I discussed with Johannes, and he decided not to support unpacked class files anymore [1]. Personally, I think there is a bug lurking there -- probably only the "plugins/" folder should have the recursive behavior described above -- but it is an edge case which we do not have time to fix right now. However, if you feel strongly about the issue, you are very welcome to submit a pull request addressing it! Otherwise, I'd encourage you to switch to an IDE, and/or JAR-based development model. Let us know if you need further guidance with it.
