Description
ADDITIONAL SYSTEM INFORMATION :
ArchLinux, OpenJDK 22

A DESCRIPTION OF THE PROBLEM :
When building using gradle with the org.gradle.parallel option set to true or the "--parallel" command line option, the build quickly fails.

However, not setting the parallel option allows the project to be built properly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
On a fresh cloning of OpenJFX's source code, launch a build with:
gradle zips --parallel

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
OpenJFX should build properly with or without gradle's parallel option.
ACTUAL -
The build fails quickly, which could point to a dependency not handled properly between subprojectfs. First to fail is controls complaining about javafx.base not found:
---
Starting a Gradle Daemon, 1 stopped Daemon could not be reused, use --status for details

I'm changing this issue type to Enhancement. As noted, the JavaFX build.gradle script does not work with the "gradle --parallel" option. It would be a fairly large effort to allow this to work, and something we would only consider doing in connection with an even larger effort to clean up and modernize build.gradle.
