使用javafx-maven-plugin创建Javafx本机安装程序时，如何指定JNLP输出文件？

Question

I'm using the maven plugin https://github.com/javafx-maven-plugin/javafx-maven-plugin to generate an installer for the javafx application. I could create a exe and run it successfully. the problem is I'm not able to generate the jnlp file. I see the below message

[INFO] Skipping WebStart JNLP Bundler because of configuration error No OutFile Specificed
Advice to Fix: Please specify the name of the JNLP Outut file in 'jnlp.outfile'

Where and how to do I set the name of the JNLP output file ?

For having JNLP-files being generated, you have to adjust your configuration a bit:

<plugin>
    <groupId>com.zenjava</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>8.2.0</version>
    <configuration>
        <mainClass>com.zenjava.test.Main</mainClass>
        <verbose>true</verbose>
        <appName>YourAwesomeProject</appName>
        <bundleArguments>
            <!-- to include "dtjava.js" and other related files, set this to TRUE -->
            <jnlp.includeDT>true</jnlp.includeDT>

            <!-- the JNLP-bundler needs this, they don't use "appName" for the filename ... you have to set this, otherwise it doesn't build -->
            <!-- for details of that JNLP-bundler, please have a look at the source -->
            <!-- https://github.com/Debian/openjfx/blob/e32fd960e20c58c9b7db27e426b4bca6d52add2f/modules/fxpackager/src/main/java/com/oracle/tools/packager/jnlp/JNLPBundler.java#L84 -->
            <jnlp.outfile>YourAwesomeProject</jnlp.outfile>
        </bundleArguments>
    </configuration>
</plugin>

You need to call mvn jfx:native instead of mvn jfx:web because Oracle is moving the JNLP-generation to a new internal form, removing some com.sun.*-packages.

To only have the JNLP being generated, you could reduce build-time by specifying <bundler>jnlp</bundler> inside the configuration.
