I have a small kotlin project using Javalin and JTE as a renderer. The project is managed with maven and below is the pom.xml.

When I run it in my IDE (IntelliJ IDEA) I have no issue. However, when I build it and run it using maven in the cli (mvn clean install and then mvn exec:java), the server starts correctly and handles correctly static ressources (like images or css files), but throws the following error when rendering a jte template :

Reset to default 0You must be using IntelliJ jte plugin, which takes care of generating source, precompiling, etc. Hence it works fine in IDE.
To build and run using CLI, you can configure the maven plugin for jte.
Refer to this possibly related issue.
