Module information .java
module com.alcamech.jomo {

opens com.alcamech.jomo to javafx.fxml;
exports com.alcamech.jomo;
}

Current
Fedora release 35 (Thirty Five), 5.15.13-200.fc35.x86_64
openjdk version "11.0.13" 2021-10-19
OpenJDK Runtime Environment 18.9 (build 11.0.13+8)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.13+8, mixed mode, sharing)
I’m following the https://openjfx.io/openjfx-docs/ The sample projects in (Modular Intellij, Modular CLI) encountered this error. Clone my project repo on Windows and run the jlink command successfully. I tried the jlink command via CLI on linux and got the same error. I opened a GitHub issue with full maven logs here https://github.com/openjfx/javafx-maven-plugin/issues/146
Debug jlink command line from MVN javafx:link output

Solution
I’m missing the jmods directory in my jdk. On Fedora, jmods are installed separately
https://fedora.pkgs.org/35/fedora-x86_64/java-11-openjdk-jmods-11.0.12.0.7-4.fc35.x86_64.rpm.html
Run sudo dnf install java-11-openjdk-jmods
