Trying to run executable jar of JavaFX app - Error: JavaFX runtime components are missing

问题

I've created a JavaFX 11 app that is ready to be deployed.

I use Gradle 5.0 as my build tool and this command to compile the jar:

jar {
    manifest {
        attributes(
                'Main-Class': 'checkmydigitalfootprint.MainApp'
        )
    }
    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
 }

Then on command line I've tried different commands to run the jar file:

java -jar CheckMyDigitalFootprint.jar

java -jar CheckMyDigitalFootprint.jar --module-path="/users/joseph/eclipse-workspace/javafx-sdk-11.0.1/lib" --add-modules=javafx.controls

java -jar CheckMyDigitalFootprint.jar --module-path="/users/joseph/eclipse-workspace/javafx-sdk-11.0.1/lib" --add-modules=javafx.controls --add-exports=javafx.graphics/com.sun.javafx.util=ALL-UNNAMED --add-exports=javafx.base/com.sun.javafx.reflect=ALL-UNNAMED --add-exports=javafx.base/com.sun.javafx.beans=ALL-UNNAMED --add-exports=javafx.graphics/com.sun.glass.utils=ALL-UNNAMED --add-exports=javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED

But all result in the same error:

Error: JavaFX runtime components are missing, and are required to run this application

Rest of build.gradle:

plugins {
  id 'application'
  id 'org.openjfx.javafxplugin' version '0.0.5'
  id 'eclipse'
}

repositories {
    mavenCentral()
}

dependencies {
    /* uncomment for cross-platform jar: */
//    compile "org.openjfx:javafx-graphics:11:win"
//    compile "org.openjfx:javafx-graphics:11:linux"
    compile "org.openjfx:javafx-graphics:11:mac"
    compile 'com.jfoenix:jfoenix:9.0.8'
    compile 'org.json:json:20180813'
    compile 'com.google.api-client:google-api-client:1.23.0'

    testCompile "org.testfx:testfx-core:4.0.15-alpha"
    testCompile "org.testfx:testfx-junit:4.0.15-alpha"
}

javafx {
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

run {
    if (osdetector.os == 'windows') {
        // Temporal fix for Eclipse with JDK 1.8 and Windows 
        systemProperty "java.library.path", "C:\tmp"
    }
}

jar {
    manifest {
        attributes(
                'Main-Class': 'checkmydigitalfootprint.MainApp'
        )
    }
    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
 }

mainClassName = 'checkmydigitalfootprint.MainApp'

回答1:

This is explained on official OpenJFX website

The solution is simple, just add following VM option:

--module-path /path/to/javafx-sdk-11.0.1/lib --add-modules=javafx.controls,javafx.fxml

for your Gradle project apply JavaFX gradle plugin

plugins {
  id 'application'
  id 'org.openjfx.javafxplugin' version '0.0.5'
}

add the required modules. e.g:

javafx {
    modules = [ 'javafx.controls' ]
}

Specify version of JavaFX

javafx {
    version = "11.0.+"
}

Hopefully this will help you :)

回答2:

I have no experience with Gradle but was having the same problem with a runnable jar giving the "JavaFX runtime components are missing...". (Using openJDK/JFX 11.) Even when the vm arguments were correctly included in the command line. The problem was the "Library handling" option for building the runnable jar. "Extract required libraries.." didn't do the job. "Package required libraries..." was the correct option for building a runnable jar file with JavaFX dependency.
