Issue
I am getting an error message when attempting to run a simple javafx application. Using netbeans 11.0, openjdk 12, openjfx12.
Can't extract module name from javafx-12.0.1.pom: Only outputDirectories and jars are accepted on the path
I had similar problems to Alex on this question, as I wanted to be able to debug: I can't debug an application using netbeans 11 with JavaFX 12
I previously to use the javafx-archetype-fxml as suggested by https://openjfx.io/openjfx-docs/
but had difficulty running.
I tried to follow the steps suggested by Jose. Using the pom (with the application name changed):-

I then modified the nbactions.xml as suggested:-

<goals>
<goal>clean</goal>
<goal>javafx:run</goal>
</goals>
</action>
<action>
<actionName>jlink</actionName>

<goal>clean</goal>
<goal>javafx:jlink</goal>
</goals>
</action>
<action>
<actionName>debug</actionName>
<goals>
<goal>clean</goal>
<goal>javafx:run@debug</goal>
</goals>
</action>
</actions>
The project will happily build with no errors.
However on trying to run the project I get the following error message:-
cd G:\OneDrive\Documents\NetBeansProjects\MavenFX; "JAVA_HOME=C:\\Program Files\\OpenJDK\\jdk-12.0.1" cmd /c "\"\"C:\\Program Files\\Netbeans 11\\java\\maven\\bin\\mvn.cmd\" -Dmaven.ext.class.path=\"C:\\Program Files\\Netbeans 11\\java\\maven-nblib\\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 clean javafx:run\""

I can't understand the line:
Can't extract module name from javafx-12.0.1.pom: Only outputDirectories and jars are accepted on the path
Solution
As discussed in the comments:
If you get the error Unrecognized option: --module-path, it means you are running with Java 1.8.
If you are running your Maven project from an IDE, it also means that your IDE is using JDK 1.8 as well.
There are two options to fix this issue:
In case of NetBeans, with the IDE closed, you can edit C:\path\to\NetBeans11.1\etc\netbeans.conf, and add the JDK 12 path, like documented here:
netbeans_jdkhome="C:\path\to\jdk-12.0.2"
Save, close the file, and open NetBeans again, and run the project, it should work. Note this is a permanent solution.
If still doesn't work, make sure you don't have in your PATH variable an older JDK. It is frequent to have the JDK bin path added to the Path environment variable, and if that is the case, that will be still chosen by your IDE.
The other option is to use <executable> in your JavaFX Maven plugin, like:
<configuration>
<executable>C:\path\to\jdk-12.0.2\bin\java</executable>
...
</configuration>
Now, regardless the JDK of your IDE, it will pick the one in that path. Obviously, this makes your pom less portable.
