我在Intellij下使用Maven编程我的第一个JavaFX v17.0项目。一切都很好，我能够创建一个JavaFX视图控制器并显示它。但是，当我将这些行添加到module-info:
时，问题出现了。requires Rserve;
requires REngine;
对应于pom.xml中的依赖项:
<!-- https://mvnrepository.com/artifact/org.rosuda.REngine/Rserve -->
<dependency>
<groupId>org.rosuda.REngine</groupId>
<artifactId>Rserve</artifactId>

<dependency>

我尝试将这些行添加到vm配置中:
--add-exports java.base/java.lang=ALL-UNNAMED --add-exports java.base/java.io=ALL-UNNAMED
但它仍然不工作。
你能解释一下错误的来源和解决方法吗?
更新事实上，RServe和REngine的依赖关系不是模块化的，但我不知道如何处理。

和module-info:

}
更新2
当运行编译命令时，我发现Intellij运行命令:
C:UsersThibault.jdksopenjdk-17.0.1binjava.exe "-javaagent:D:IntelliJ IDEA 2021.2.2libidea_rt.jar=52247:D:IntelliJ IDEA 2021.2.2bin" -Dfile.encoding=UTF-8 -classpath "D:ProgrammationMASI1.5CarteAPuceJavaCardsToolslibapi_classic-3.1.0.jar;D:JavaProgMASI_Projet_IntegremavenJava11Projecttargetclasses;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx-swt.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.web.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.base.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.fxml.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.media.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.swing.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.controls.jar;C:Program FilesJavaFXjavafx-sdk-17.0.6libjavafx.graphics.jar;C:UsersThibault.m2repositoryorgrosudaREngineRserve1.8.1Rserve-1.8.1.jar;C:UsersThibault.m2repositoryorgrosudaREngineREngine2.1.0REngine-2.1.0.jar" root.switchscene.SwitchSceneApp --module-path C:Program FilesJavaFXjavafx-sdk-17.0.6lib --add-modules javafx.controls,javafx.fxml
在这里，我们可以看到在类路径中有一个jar' api_classic-3.1.0.jar'，但是我从来没有指定它，我如何从自动命令中删除它?
我发现问题来自于'D: programming MASI1.5 carpusuce JavaCardsToolslibapi_classic-3.1.0.jar'添加的jar。由于我无法从Intellij自动命令中删除这一行，所以我删除了jar，现在一切正常。这可能不是最好的方法，但它是有效的。
