【中文标题】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【英文标题】:Error occurred during initialization of boot layer. plexus.container.default: Invalid module name: 'default' is not a Java identifier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 【发布时间】:2021-05-24 16:05:56 【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] 无法从中提取模块名称 plexus-container-default-1.7.1.jar:plexus.container.default:无效 模块名称:'default' 不是 Java 标识符

[警告] 一些依赖项在尝试使用时遇到问题 解析为模块,不会包含在类路径中;你可以 通过“includePathExceptionsInClasspath”更改此行为 配置参数。

应用程序正常运行。

但是,当我尝试在 IDE 中简单地运行 Main 类时,我收到了一个错误:

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。您有什么建议可以尝试?

删除对 maven-dependency-plugin 的依赖后,错误消失了,但现在我在尝试运行 Main 类时遇到其他错误:

Build output 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;

【问题讨论】:

移除对maven-dependency-plugin的依赖... @khmarbaise 谢谢,我删除了对 maven-dependency-plugin 的依赖,错误消失了。但是现在当我尝试运行 Main 类时,我得到了其他错误,我在 qustion 编辑中描述了这些错误。你能看看吗? 依赖 javafx-controls 既不是模块(从我的角度来看)也不是可用的工件...... 【参考方案1】:

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>

        <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>

换句话说,只是将javafx依赖版本编辑为16-ea+1。 现在一切正常。
