Java FX projekt add dependency failed

Since yesterday's "Project Manager for Java" release, additional dependencies added to JavaFX do not work.

I am making a Java FX project. This is based on Maven. It works.

When I add an extra dependency like Gson.

com.google.code.gson gson 2.11.0

I write in the code:

Gson gson = new Gson();

I import as usual.

The dependency cannot be used. VSCode says Gson cannot be resolved. It is there in the pom.xml file, and the import is also there in the code.

I saw that other people had previously written that, due to modularization, the following must be entered in the module-info.java file:

requires com.google.gson;

But even this instruction gives me trouble, you can't even find the module here.

I used it 3 days ago and there were no problems with it.

Have you tried right click on the pom file and select Reload Project?

Hello jdneo!

Not before your message, but I tried. Of course it doesn't help.
I also tried "mvn clean install", etc.

But I have since narrowed down the problem. The error only occurs with the latest version of Gson, which is: 2.11.0

The problem only occurs when I use JavaFX. I see that the point is not JavaFX, but the modular program (module-info.java). I'm writing a simple Maven project that works non-modularly on Gson 2.11.0.

Let's stick with the modular JavaFX program:
If I switch back to the previous version of Gson, 2.10.1 or earlier, it works.

I looked into the Gson source code. Earlier versions of Gson are also modular. So it's not a problem. I see they introduced a new thing: proguard. I just suspect that might be causing the problem. I didn't go through it in detail.

The concrete phenomenon:

If you have this in pom.xml:

<dependency>
 <groupId>com.google.code.gson</groupId>
 <artifactId>gson</artifactId>
 <version>2.11.0</version>
</dependency>

I have a line like this in the module-info.java file:

 //...
 requires com.google.gson;
 opens com.example to javafx.fxml, com.google.gson, hu.szit.resclient;

After the word requires, com.google.gson is underlined in red. If I move the mouse towards it, it says:
"com.google.gson cannot be resolved to a module"

(
Gson 2.11.0 also works in NetBeans for Maven-based and modular JavaFX projects.
)

Would you mind sharing a sample project for this issue?

Here it is:
https://github.com/andteki/samplefx.git

Now, the Gson version is 2.11.0, so not working.
If you write the version 2.10.1, then works.

https://central.sonatype.com/artifact/com.google.code.gson/gson

Looks like it's a bug from upstream:

Related issues:
google/gson#2721
eclipse-jdt/eclipse.jdt.core#2495

For now the workaround is to use gson@2.10.1

Sorry for the inconvenience.

Thank you for your work!
