Strange run error re mainClass value

[arnieHouston]

I have a multi-module maven project. One submodule (myappname-app) is the only place the plugin is mentioned. And yet, I get the below error when Maven processes and parent POM instead of the module's POM when using only the javafx:run goal.

Failed to execute goal org.openjfx:javafx-maven-plugin:0.0.8:run (default-cli) on project appModule: The parameters 'mainClass' for goal org.openjfx:javafx-maven-plugin:0.0.8:run are missing or invalid.

It's like it's applying this config at the wrong level instead of the sub-module. Do I need to add a specific GOAL setting?

Config from sub-module POM, not the parent POM:

<plugin> <groupId>org.openjfx</groupId> <artifactId>javafx-maven-plugin</artifactId> <configuration> <jlinkExecutable>/Library/Java/JavaVirtualMachines/jdk-22.0.1.jdk/Contents/Home/bin/jlink</jlinkExecutable> </configuration> <executions> <execution> <id>default-cli</id> <configuration> <mainClass>appModuleName/a.b.c.d.App</mainClass> <options> <option>--add-opens</option> <option>java.base/java.lang=a.b.c.d</option> </options> </configuration> </execution> </executions> </plugin>
