I am trying to follow this tutorial to set a Maven JavaFX project in IntelliJ https://openjfx.io/openjfx-docs/#maven (IntelliJ non-modular with Maven) but it fails whatever I do.

I have been trying a lot of internet advice. I tried setting VM variables in the pom, I made sure JAVA_HOME is pointing to my JDK 12 directory, and I checked that in the project structure the JDK is correctly set.

This is my pom file: 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

As José Pereda indicates, the important error message is java.lang.module.InvalidModuleDescriptorException: Unsupported major.minor version 55.0

  • You are running from IntelliJ with a JDK lower than 12, and that's why it fails with `Unsupported major.minor version 55.0`. Try to set the project structure to level 12, and try again. It is also convenient to add a new Maven configuration, and run `mvn clean javafx:run` directly. You could also set `path.to.java in the plugin's configuration, but this is less portable. – José Pereda Aug 25 '19 at 21:33
  • Thanks for your comment. I just checked and project structure is already at level 12. I have created a new run configuration as you indicate but I still get the same error. – Pedro Victori Aug 25 '19 at 21:51
  • Make sure you don't have in your Path variable and older JDK. – José Pereda Aug 25 '19 at 21:57
  • No, the only one in my Path is C:\Program Files\Java\jdk-12.0.2\bin I also tried setting the path to java in the plugin configuration like this: `C:\Program Files\Java\jdk-12.0.2\bin` but I get the same error. – Pedro Victori Aug 25 '19 at 22:05

I solved it, although in a somewhat radical way. For some reason, java -version returned a different Java version, 10. I deleted all JDKs from my computer and reinstalled JDK 12, and now the problem is solved. Thanks to José Pereda for his help pinpointing the issue!

This can also happen when running from netbeans (showed up for me when updating java version).
The solution is taken from here

You'll need to update this variable with the location of your jdk (even if you already have JAVA_HOME set up)
netbeans_jdkhome="C:\Program Files\Java\jdk<version>
this is located in this file
C:\Program Files\NetBeans <version>\netbeans\etc\netbeans.conf
