The theme.res file is not being created in new projects. It is however being created in demo projects. I can copy the file from a demo to my new project, but this is annoying and gives little control over the appearance.

Exception: java.io.IOException - /theme.res not found

We deprecated the plugins a while back so you shouldn't use them to create a project. You should use https://start.codenameone.com/ as explained on the Codename One website.

The maven support doesn't need a plugin and works with all IDEs as explained here: https://shannah.github.io/codenameone-maven-manual/

  • Thanks. I've encountered errors with this new method now. But I've posted it as a new question [here](https://stackoverflow.com/questions/71820771/errors-importing-and-running-codename-one-maven-project-using-eclipse-windows-1) – Kyros Nox Apr 11 '22 at 00:15
