Module reads package ... from both java.base and api.classic

I am programming my fisrt JavaFX v17.0 project using Maven under Intellij. Everything was fine, I was able to create a JavaFX view-controller and to display it. But the problem came when I added these lines to the module-info :

 requires Rserve;
 requires REngine;

Which corresponds to those dependencies in the pom.xml:

        <!-- https://mvnrepository.com/artifact/org.rosuda.REngine/Rserve -->
        <dependency>
            <groupId>org.rosuda.REngine</groupId>
            <artifactId>Rserve</artifactId>
            <version>1.8.1</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/org.rosuda.REngine/REngine -->
        <dependency>
            <groupId>org.rosuda.REngine</groupId>
            <artifactId>REngine</artifactId>
            <version>2.1.0</version>
        </dependency>

When I compile, I get these errors :

...
Checking sources
Copying resources... [first-javafx-try]
Parsing java... [first-javafx-try]
java: the unnamed module reads package java.io from both api.classic and java.base
java: the unnamed module reads package java.lang from both api.classic and java.base
java: module api.classic reads package java.lang from both java.base and api.classic
java: module api.classic reads package java.io from both java.base and api.classic
java: module REngine reads package java.lang from both java.base and api.classic
java: module REngine reads package java.io from both java.base and api.classic
java: module Rserve reads package java.lang from both java.base and api.classic
java: module Rserve reads package java.io from both java.base and api.classic
Checking dependencies... [first-javafx-try]
...

I tried adding these lines to the vm configuration :

--add-exports java.base/java.lang=ALL-UNNAMED --add-exports java.base/java.io=ALL-UNNAMED

But it still doesn't work.

Could you provide some explanation about the source of the errors and a way to solve them please ?

UPDATE

In fact, the dependencies RServe and REngine are not modularized, but I don't know how to deal with that.

For more information, here is the full pom.xml:

                        <!-- Default configuration for running with: mvn clean javafx:run -->

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

And the module-info :

module root {
    requires javafx.controls;
    requires javafx.fxml;
    
    requires Rserve;
    requires REngine;

    opens root.circlepong to javafx.fxml;
    exports root.circlepong;

    opens root.switchscene to javafx.fxml;
    exports root.switchscene;

    opens root.mvvmfxFirsttry to javafx.fxml;
    exports root.mvvmfxFirsttry;
}

UPDATE 2

When running the compile command, I found out that Intellij runs the command :

C:\Users\Thibault\.jdks\openjdk-17.0.1\bin\java.exe "-javaagent:D:\IntelliJ IDEA 2021.2.2\lib\idea_rt.jar=52247:D:\IntelliJ IDEA 2021.2.2\bin" -Dfile.encoding=UTF-8 -classpath "D:\Programmation\MASI1.5\CarteAPuce\JavaCardsTools\lib\api_classic-3.1.0.jar;D:\JavaProg\MASI_Projet_Integre\mavenJava11Project\target\classes;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx-swt.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.web.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.base.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.fxml.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.media.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.swing.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.controls.jar;C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib\javafx.graphics.jar;C:\Users\Thibault\.m2\repository\org\rosuda\REngine\Rserve\1.8.1\Rserve-1.8.1.jar;C:\Users\Thibault\.m2\repository\org\rosuda\REngine\REngine\2.1.0\REngine-2.1.0.jar" root.switchscene.SwitchSceneApp --module-path C:\Program Files\JavaFX\javafx-sdk-17.0.6\lib --add-modules javafx.controls,javafx.fxml

Here we can see that there is the jar 'api_classic-3.1.0.jar' in the classpath but I never specified it, how can I remove that from the automatic command ?

I found out that the problems come from the 'D:\Programmation\MASI1.5\CarteAPuce\JavaCardsTools\lib\api_classic-3.1.0.jar' jar added. As I was not able to remove theline from the Intellij automatic command, I deleted the jar and now everything works fine. This is probably not the best way to do it, but it works.
