JavaFX Problem: Can't compile JavaFX program

Windows 10, OpenJDK 17.0.2, JavaFX 17.0.2,

Java directory:
D:\Program Files\Java\jdk-17.0.2\

JavaFX directory:
D:\Program Files\Java\jdk-17.0.2\javafx\

Set environment variable PATH:
PATH=D:\Program Files\Java\jdk-17.0.2\bin\

Set environment variable JAVA_HOME:
JAVA_HOME=D:\Program Files\Java\jdk-17.0.2\

Set environment variable PATH_TO_FX:
PATH_TO_FX=“D:\Program Files\Java\jdk-17.0.2\javafx\lib”

Test compilation:
samples-master\HelloFX\CLI\hellofx\HelloFX.java

javac --module-path %PATH_TO_FX% --add-modules javafx.controls HelloFX.java

Error message:
error: no source files

I confirm that HelloFX.java exists in the current directory. How come the error message says “no source files”?
