Failed to compile with module-info.java

JahnGeor commented 4 months ago

Hi! I'm new to Java development, so I apologize in advance if the question turns out to be stupid, but I couldn't find an answer to my question on the Internet. I need to create an HTML page by template to send it for printing via JavaFX modules. However, if the module-info file is present in the project, then an error appears during the compilation of the project:

There is no error without the module-info.java file and everything functions as expected. Please tell me how to modify the module-info file.java or my code to make project compiles without an error? Thanks!

Current file module-info.java is

open module com.example.demo2 {
    requires javafx.controls;
    requires javafx.fxml;
    requires gg.jte;
    requires gg.jte.runtime;
}

Project structure:

Executable code:

        CodeResolver codeResolver = new ResourceCodeResolver("jte");
        TemplateEngine templateEngine = TemplateEngine.create(codeResolver, ContentType.Html);
        TemplateOutput output = new StringOutput();
        templateEngine.render("example.jte", new Body("Hello", "World"), output);

Hi @JahnGeor,

I haven't used Java modules seriously so far, so have no pointer for you in the right direction.

I guess the Java Compiler would need a hint to allow access of your module, when compiling jte files.

There is this method TemplateEngine#setCompileArgs. Maybe you can specify there that this module is accessible?

First of all, I would like to thank you very much for your response! After doing some research, I found the "precompilation" feature on the "gg.jte" web page and decided to use it through the "Maven" plugin. Everything is working as expected!
