Exception running application de.informatik.gitlab2.itv.Main

There are two external dependencys (controlsfx and jdom2) which are inclouded via maven in the gradle build file.

This is the build.gradle file im using:

version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.8
repositories {
    mavenCentral()
}
configurations {
    libs
}
dependencies{
    testCompile group: 'junit', name: 'junit', version: '4.12

    // https://mvnrepository.com/artifact/org.jdom/jdom
    libs group: 'org.jdom', name: 'jdom', version: '2.0.0'
    // https://mvnrepository.com/artifact/org.controlsfx/controlsfx
    libs group: 'org.controlsfx', name: 'controlsfx', version: '8.40.14'

configuration.compile.extendsFrom(configurations.libs)
}
jar {
    manifest {
        attributes 'Main-Class': 'de.informatik.gitlab2.itv.Main'
    }
    from {
        configurations.libs.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

EDIT

After adding

compile group: 'net.java.openjfx.backport', name: 'openjfx-78-backport-compat', version: '1.8.0.1'

into the build.gradle this Error occurs:

Exception running application de.informatik.gitlab2.itv.Main

EDIT2 I've edited the build.gradle file :

version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'application'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()

}

dependencies {

//
    // https://mvnrepository.com/artifact/org.jdom/jdom
    compile (
            [group: 'org.jdom', name: 'jdom', version: '2.0.0'],
            [group: 'org.controlsfx', name: 'controlsfx', version: '8.40.14'],
            [group: 'net.java.openjfx.backport', name: 'openjfx-78-backport-compat', version: '1.8.0.1']
    )
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

mainClassName = 'de.informatik.gitlab2.itv.Main'

jar {
    manifest {
        attributes( 'Main-Class': 'de.informatik.gitlab2.itv.Main',
                'Class-Path' : configurations.compile.collect{ it.getName() }.join(''))
    }
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
}

After making a clean Gradle build this is the code of the MANIFEST.MF

Manifest-Version: 1.0
Class-Path: jdom-2.0.0.jarcontrolsfx-8.40.14.jaropenjfx-78-backport-co
 mpat-1.8.0.1.jar
Main-Class: de.informatik.gitlab2.itv.Main

And here is the structure of the jar:

...
css
de
fxml
impl
java
javax
lang
META-INF
netscape
nodes
org
sun
controlsfx.properites

My two dependencies are in der folder 'org'. Shouldnt be in the Manifest a classpath with org/...? And is it a mistake that there are no whitespaces in the MANIFEST.MF between the different dependencies and if how do i solve it?

The Exception when running from the cmd is the same as above:

Exception in Application start method
Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: com/sun/javafx/scene/control/skin/BehaviorSkinBase
        at org.controlsfx.control.PropertySheet.createDefaultSkin(PropertySheet.java:254)

Answer 1

Could be because of multiple jdks or the current jdk doesn't support the skin (controlfx)... Settings worked for me (Java 8, Javafx 8), you can check similar openjfx - Goto File > Project Structure >

• Project

  • Project SDK = 1.8
  • Project Language Level = 8

• Libraries

  • controlfx 8.40.14

Answer 2

The class com.sun.javafx.scene.control.skin.BehaviorSkinBase belongs to the

JavaFX 78 Backport Compatibility Library » 1.8.0.1

Please add the following gradle dependency in your build.gradle file:

compile group: 'net.java.openjfx.backport', name: 'openjfx-78-backport-compat', version: '1.8.0.1'

Reference: https://mvnrepository.com/artifact/net.java.openjfx.backport/openjfx-78-backport-compat/1.8.0.1
