Headless Launcher config not working

[zemudkram]

Hi,

I'm trying to set up a small Swing Application using a HeadlessLauncher. I've used the configuration as described in #73, adding the following to pom.xml after embed-manifest-in-launcher:

<execution>
    <id>configure-headless-launcher</id>
    <phase>package</phase>
    <goals>
        <goal>exec</goal>
    </goals>
    <configuration>
        <executable>jar</executable>
        <workingDirectory>${app.dir}</workingDirectory>
        <arguments>
            <argument>uef</argument>
            <argument>fxlauncher.HeadlessMainLauncher</argument>
            <argument>fxlauncher.jar</argument>
        </arguments>
    </configuration>
</execution>

However, it's not working when I issue a mvn clean package install, failing with the following messages:

[INFO] --- exec-maven-plugin:1.4.0:exec (installer) @ flaunchertest ---

I'm using version 1.0.19 on MacOS, and the rest of the configuration is pretty much copied from the example Maven project. I'm assuming I've done something stupid, but I'm not quite sure what it is.

Thoughts?

To answer my own question, I also needed to update the appclass argument in the installer execution:

 <argument>-appclass</argument>
 <argument>fxlauncher.HeadlessMainLauncher</argument>
