raspberry pi + maven + jdk1.8 + javafx

Question

我正在開發一個必須在樹莓派上運行的JavaFx應用程序。 我遵循了所有步驟在Raspberry上安裝jdk1.8，下載maven 3.1.1並將項目複製到我的樹莓上。

當運行

mvn clean package 

生成成功，但是當我運行命令

java -cp app.jar my.main.class 

如這裏描述的（https://wiki.openjdk.java.net/display/OpenJFX/OpenJFX+on+the+Raspberry+Pi#OpenJFXontheRaspberryPi-RunningaJDKEarlyAccessbuildontheRaspberryPi）

我收到此錯誤：

任何人都可以幫我嗎？我已經包括了jfxrt我pom.xml

這是它：

Answer 1

您應該直接看http://zenjava.com/javafx/maven/

JavaFX的Maven插件：https://github.com/zonski/javafx-maven-plugin

這是一個偉大的插件構建javafx應用程序，您可以使用其命令將jfxrt.jar鏈接到maven版本：

mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath 

下面是命令的描述：http://zenjava.com/javafx/maven/fix-classpath.html

我也引用：

If you don't want to use the fix-classpath Maven command or have problems when running it. You can try manually moving the JAR file yourself from the lib directory to the ext directory. There is no more magic required than that.
