Maven：如何在 Maven 中使用 JMetro 样式？

Question

我想在我的 Maven 项目中使用 JMetro 样式，但无论我做什么，Maven 都会给我同样的错误。我正在使用来自org.openjfx 的javafx-archetype-simple，我尝试通过将其作为依赖项添加到我的pom.xml 中来使用JMetro，并通过将.settings.xml 添加到~/.m2/ 来从JCenter 下载它。每当我在mvn clean 之后尝试做mvn javafx:run 时，我总是会收到这个错误：

链接到Gist 包含我编辑的pom.xml、settings.xml 和App.java，我曾经尝试在我的项目中使用JMetro。源代码（不含 JMetro，实际使用 mvn clean javafx:run 运行）linked here。

java -version 的输出：

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10)
OpenJDK 64-Bit Server VM (build 11.0.6+10, mixed mode)

mvn --version 的输出：

PS：我对使用 Maven 真的很陌生，我非常感谢一些关于使用 Maven 的建议，一般来说，以及在其上使用 JavaFX。最初，在Github Issues、JFXtras Styles Git repo 上发布了这个问题，但这并不是 JMetro 本身的问题，所以在这里发布了这个问题。

额外信息：我不知道这是否与它有关，但我仍然将其添加为参考。当我将 JMetro 11.6.7 添加为依赖项并重新运行 mvn clean javafx:run 时，在下载时，它给了我这些警告，

...
[WARNING] Can't extract module name from jmetro-11.6.7.pom: zip END header not found
...
[WARNING] Can't extract module name from jmetro-11.6.7.pom: Only outputDirectories and jars are accepted on the path
[WARNING] Some dependencies encountered issues while attempting to be resolved as modules and will not be included in the classpath; you can change this behavior via the  'includePathExceptionsInClasspath' configuration parameter.

Answer 1

JMetro 的官方 Maven 存储库也不适合我。我求助于从 GitHub 下载 JMetro jar，手动将其添加到 Maven，然后在我的 JavaFX 应用程序中使用它。

以下是我为使 JMetro 与 Maven 更好地配合所做的工作：

1. 从GitHub下载官方JMetro jar

2. 将下载的jar添加到本地Maven repo：

   mvn install:install-file -Dfile=jmetro-11.6.15.jar -DgroupId=com.jfxtras -DartifactId=jmetro -Dversion=11.6.15
   

3. 将其作为依赖项添加到项目的pom.xml：

   <dependency>
       <groupId>com.jfxtras</groupId>
       <artifactId>jmetro</artifactId>
       <version>11.6.15</version>
   </dependency>
   

4. 对于模块化项目，请在项目的module-info.java 中声明：

   module <ModuleName> {
       ...
       requires org.jfxtras.styles.jmetro;
       ...
   }
   

现在JMetro可以正常使用了。
