java - 引导层初始化期间发生错误。plexus.container.default：无效的模块名称：'default' 不是 Java 标识符

问题描述

我正在为我的应用程序使用 IntelliJ IDEA 2020.2.3 和 maven。

当我尝试调用 maven javafx:ru​​n 插件（就像每个 maven 插件一样）时，我收到了这样的警告：

[警告] 无法从 plexus-container-default-1.7.1.jar 中提取模块名称：plexus.container.default：无效的模块名称：“默认”不是 Java 标识符

[警告] 某些依赖项在尝试作为模块解析时遇到问题，不会包含在类路径中；您可以通过“includePathExceptionsInClasspath”配置参数更改此行为。

该应用程序正常工作。

但是，当我尝试在 IDE 中简单地运行 Main 类时，出现错误：

Error occurred during initialization of boot layer
java.lang.module.FindException: Unable to derive module descriptor for C:\Users\hlebs\.m2\repository\org\codehaus\plexus\plexus-container-default\1.7.1\plexus-container-default-1.7.1.jar
Caused by: java.lang.IllegalArgumentException: plexus.container.default: Invalid module name: 'default' is not a Java identifier

这是我的 pom.xml：

我想运行 Main 类而不是运行 javafx:ru​​n 插件，因为当我测试某些功能时，它对我来说有点长且有害。另外我认为这样的错误不是正常情况。你有什么建议可以尝试？

删除对 maven-dependency-plugin 的依赖后，错误消失了，但现在在尝试运行 Main 类时出现其他错误：

构建输出 Printscreen

我的 module-info.java 看起来像：

module org.openjfx {
    requires javafx.controls;
    requires javafx.fxml;

    requires org.kordamp.ikonli.core;
    requires org.kordamp.ikonli.javafx;
    requires org.kordamp.ikonli.fontawesome;
    requires org.kordamp.ikonli.remixicon;
    requires java.sql;
    requires java.desktop;

    opens org.openjfx to javafx.fxml;
    opens org.openjfx.ledicom.entities to javafx.base;
    opens org.openjfx.ledicom.controllers.employee to javafx.fxml;
    opens org.openjfx.ledicom.controllers.notifications to javafx.fxml;
    opens org.openjfx.ledicom.controllers to javafx.fxml;
    exports org.openjfx.ledicom.entities to java.sql;
    exports org.openjfx;
}

解决方案

在 pom.xml 我改变了

        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>15.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-fxml</artifactId>
            <version>15.0.1</version>
        </dependency>

至

        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>16-ea+1</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-fxml</artifactId>
            <version>16-ea+1</version>
        </dependency>

也就是说，只是将javafx依赖版本编辑为16-ea+1。现在一切正常。
