java - Javafx 项目不能用 maven 编译

Question

我有一个 Java FX 项目，并且正在使用 maven 3.0.5 来构建。当我运行 mvn package/install 时，项目失败并抱怨包 javafx. *不存在。据我了解，Javafx 打包在 Java 1.7 中，因此构建不支持它是没有意义的。当我在我的 IDE (intellij) 中编译它时，它工作正常，之后我的 maven 构建也成功安装，但是我不希望每次进行全新安装时都必须通过 IDE。有任何想法吗？

这是我的pom：

谢谢您的帮助。

Answer 1

将其放在依赖项中（取决于您的 jdk 所在的位置）将有助于编译依赖项，但是您可能应该将其替换为用户可以在其 settings.xml 或 maven 系统属性中指定的变量：

    <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>javaFX</artifactId>
        <version>2.2</version>
        <scope>system</scope>
        <systemPath>C:\Program Files\Java\jre7\lib\jfxrt.jar</systemPath>
    </dependency>

有关原因的更多详细信息，请参阅带有 JavaFX 的 Maven 项目（在 `lib` 中有 jar 文件）

Answer 2

如果您在使用 Maven 的 JavaFx 版本 17 的模块化项目中遇到这些错误，只需尝试通常的事情，例如站在头上、在天花板上行走、向相反方向旋转地球，甚至阅读https://openjfx.io/ openjfx-docs/然后切换到 17.0.1 或更高版本，它应该可以工作：

<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-controls</artifactId>
    <version>17.0.1</version>
</dependency>

Answer 3

这个解决方案对我有用。

将 sample.fxml 移动到资源文件夹。这需要将您的代码更改为 getResource("/sample.fxml")。
