Can't build javafx project with gradle in intellij idea

Question

I build my project using gradle jar command, then try to start my application using command java -jar MyProject.jar

After that I have error:

Error: Could not find or load main class org.apdalgo.Main<br>
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

My build.gardle:

    plugins {
        id 'java'
        id 'application'
        id 'org.openjfx.javafxplugin' version '0.0.7'
    }
    
    group 'org.apdalgo'
    version '1.0-SNAPSHOT'
    
    sourceCompatibility = 11
    
    repositories {
        mavenCentral()
    }
    
    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.12'
    }
    
    javafx {
        version = "12"
        modules = [ 'javafx.controls', 'javafx.fxml' ]
    }
    
    mainClassName = 'org.apdalgo.Main'
    
    jar {
        manifest {
            attributes 'Main-Class': 'org.apdalgo.Main',
                    'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' ')
        }
        from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    }
