Errors during compiling when using modules

Hi,

In my project (JDK 13, JavaFX 13, Maven) after I build it successfully the build fails when I modify my code and build it again. I get the following message:

Error:java: java.lang.module.FindException: Error reading module: <path to project root>\target\classes

I need to delete the target folder, then build it again, this time it's working.
