How can I add a JavaFX 2.0 class to an existing Ma

Question

I have a Maven project that just displays a graph on the xy axis. I want to change that graph to a Javafx 2.0 linechart to display the same data. I tried using the FEST-javafx-maven plugin, but I still cannot compile the code; the compiler cannot find all of the javafx.xxx imports.

Any help would be appreciated.

Update (Oct 6 2015)

Modern JavaFX versions (shipped with Oracle Java 8+) do not require any additional class path to use JavaFX. The JavaFX runtime is on the default classpath Java uses for compilation and execution. This means that a plain maven pom.xml file, with no additional dependencies, will build a JavaFX application.

However, if you wish to use additional packaging features for your application, such as the ability to deploy it as a self-contained application, then I advise using the (third party) JavaFX Maven plugin.

Previous Answer

The following information in this answer is now mostly old and outdated.

The link to the fest maven plugin I found (http://fest.easytesting.org/javafx/maven/) is to a tool for building JavaFX 1.x script projects, which is a completely different and incompatible beast to JavaFX 2.0 - I'm not sure if there is an updated version of the fest maven plugin which supports JavaFX 2.0.

There is currently no official support for Maven from Oracle, nor a version of JavaFX 2.0 in a publicly hosted Maven repository.

However, I have successfully built JavaFX 2.0 projects using maven in the past by using a system scoped dependency on the jfxrt.jar and (optionally) invoking the JavaFX ant tasks from maven.

If you are embedding your graph in an existing Swing application via a JFXPanel, then you don't need to use the JavaFX ant tasks. Add jfxrt.jar from the JavaFX runtime as a system dependency OR manually install it into your maven repository to use a non-system scoped dependency.

An example of the command to manually install the required JavaFX 2.0 runtime jar is:

mvn install:install-file -Dfile="C:\Program Files\Oracle\JavaFX 2.1.0 SDK\rt\lib\jfxrt.jar" -DgroupId=com.oracle.javafx -DartifactId=javafx -Dversion=2.1 -Dpackaging=jar

After running the above command, add the dependency to the jfxrt.jar file to your maven pom and your project compilation should resolve all JavaFX API references:

<dependency>
  <groupId>com.oracle.javafx</groupId>
  <artifactId>javafx</artifactId>
  <version>2.1</version>
</dependency>

If you extend the JavaFX Application class and you want your application packaged for deployment via webstart, browser embedding or as a JavaFX installation aware clickable jar, then you should adapt your pom.xml file to execute the relevant JavaFX 2.0 ant tasks - http://code.google.com/p/willow-browser/source/browse/pom.xml demonstrates such an adaption.

Answer 2

Using JDK 1.7 you have to perform the following mvn goal.

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

This command will change the classpath of your JRE and copy the jfxrt.jar to the JAVA_HOME\lib\ext directory.

Take an additional look here for further information: JavaFX Maven Plugin

Within your pom-file you have to add the following dependency configuration.

     <dependency>
        <groupId>javafx</groupId>
        <artifactId>jfxrt</artifactId>
        <version>2.2</version>
        <!-- <version>${javafx.min.version}</version> -->
        <scope>system</scope>
        <systemPath>${java.home}/lib/ext/jfxrt.jar</systemPath>
    </dependency>

Answer 3

I had the same problem and here is my solution:

If using Java 7u7 (javafx is integrated into jdk/jre):

    <dependency>
        <groupId>javafx</groupId>
        <artifactId>javafx</artifactId>
        <version>2.1</version>
        <scope>system</scope>
        <systemPath>${java.home}/lib/jfxrt.jar</systemPath>
    </dependency>

For previous versions of java:

    <dependency>
        <groupId>javafx</groupId>
        <artifactId>javafx</artifactId>
        <version>2.1</version>
        <scope>system</scope>
        <systemPath>${env.JAVAFX_HOME}\rt\lib\jfxrt.jar</systemPath>
    </dependency>

And you have to set system variable JAVAFX_HOME to home dir of JavaFx.

You might try the JavaFX Maven plugin. This takes care of adding javafx to the classpath as well as building JavaFX apps and creating Windows/Mac/Linux executables, as well as double-clickable JARs and JNLP files.
