JavaFX FatJar using Gradle and IntelliJ

I've tried everything by now, so I hope someone in here can tell me more...
Im trying to produce an executable .jar from a IntelliJ Gradle JavaFX project. I used the standard setup that IntelliJ provided, I changed the Gradle.build file however.
The new file I got from here: Non-Modular Gradle (openjfx.io)
I have a main class that has some basic code in it and a launcher class that does not extend Application and is specified as the Main class in the jar manifest.
For now I only use javafx.controls and basically everything is as the example they provided here.
When doing the ./gradlew jar command I get the error:
no module-info.java found
Which - as I understand - is not required if I use the Non-Modular approach?
However if I add it I get the error:
Entry module-info.class is a duplicate but no duplicate handling strategy has been set.
I tried every other option out there, all of them lead to either the 2. error or the jar was produced but not executable due to the fact that it can't find the Application class...
Any help is greatly appreciated.
I just want to point out that I've never really used Gradle before and have never formally learned any coding, but can fiddle my way around usually.
For the sake if it my build file:
plugins {
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.9' // this is old right?
}
repositories {
mavenCentral()
}
dependencies {
/* uncomment for cross-platform jar: */
runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:win"
runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:linux"
runtimeOnly "org.openjfx:javafx-graphics:$javafx.version:mac"
}
javafx {
version = "16"
modules = [ 'javafx.controls' ]
}
mainClassName = 'main.class.with.Code'
jar {
manifest {
attributes 'Main-Class': 'main.class.with.Launcher'
}
from {
// this is what causes the module duplicate error I think (at least it did in my other tries)
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
}

Unable to add library to Android Studio project

I'm trying to add this library to Android Studio locally using this tutorial on YouTube.
However, I get errors that I can't post here because they're too many (99+).
Can someone tell me step by step (in detail) how to succesfully add this library to my project and be able to edit it afterwards?
This is the main error I get when I try to import this library: `Unable to determine constructor argument #1: missing parameter of type Factory, or no service of type Factory.
My build.gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.0.0"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.72"
classpath 'com.github.dcendents:android-maven-plugin:1.2'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.8.4'
classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Here is your step-by-step guide:
Create an empty project or open your existing project where you want to add this library.
Clone the library project from the git or download the zip and extract it in some other directory.
Now, in Android Studio, go to File -> New -> Import Module.... Select the cloned/extracted library directory. Make sure the :placepicker module is selected for import. Then click Finish.
Now copy two files bintray.gradle and install.gradle from cloned/extracted project root directory to your own project root directory. Add this point your project structure should look like this:
Now open your project level build.gradle. Add ext.kotlin_version = '1.3.72' inside buildscript { and also add following dependencies:
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.8.5'
classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
Overall, this will look like:
Finally, go to File -> Sync Project with Gradle Files. It will take some time to download the missing dependencies and you have now successfully integrated the library within your project which is fully editable.
Now to make this library work in your own app module, in the build.gradle file of your app module, add this inside dependencies section:
api project(':placepicker')

Or edit your gradle.build like in the picture:

Step by step description:
Then ceck out the git project to your machine.
Modify and build it with a new Version.
Add the dipendency as Jar from Your local filesystem in Android Studio.
Try this:
File > Project Structure > Dependencies Tab > Add module dependency (scope = compile)
Where the module dependency is the project library Android folder.

In build.gradle(Module.app) file add this.
implementation 'com.google.android.gms:play-services-places:17.0.0'
let me knew if it's work.

Include pom.xml in Jar with gradle

I'm attempting to include a generated pom.xml in the jar that I'm creating with gradle.
So far, in my parent project, I have
subprojects {
apply plugin: 'maven-publish'
publishing {
publications {
maven(MavenPublication) {
from(components.java)
}
}
}
}
and in the sub-project I have:
tasks.build.dependsOn install
sourceSets {
main {
resources {
srcDirs = [ "src/main/resources", "build/poms" ]
}
}
}
This will generate ./build/poms/pom-default.xml, but it will not add it to the JAR.
Creating a dependency on an earlier phase than build creates circular dependencies (and I don't know whether this is the problem anyway).
Also, I'd like the pom.xml to show up inside META-INF with name pom.xml (not pom-default.xml), so this may not be the right approach anyway.
Somehow I'm thinking it can't be as complicated as this looks?

You should be able to include the POM in your JAR by adding the following to your subprojects closure:
jar {
into("META-INF/maven/${project.group}/${project.name}") {
from generatePomFileForMavenPublication
rename { it.replace('pom-default.xml', 'pom.xml') }
}
}
If you already have a jar closure, you can add it there. This automatically creates a task dependency on the generatePomFileForMavenPublication task, so that the POM file is there when the JAR is created.
The sourceSets part from your question would not be required for this.
(Side note: It would not be strictly necessary to do this at all, because the Maven publish process will publish the POM as an individual artifact anyway.)

Publish Android library with external dependencies

I have an Android closed source module that will be be used as a library in other projects. It contains external dependencies.
To publish it, I'm creating a Maven artifact with the following gradle task:
apply plugin: 'maven'
def coreAarFile = file('...build\\outputs\\aar\\android-sdk-release.aar')
artifacts {
archives coreAarFile
}
uploadArchives {
repositories.mavenDeployer {
repository(url: "file://.\\mvn-repo")
pom.project {
groupId 'a.blabla'
artifactId 'blabla-sdk'
version "1.0.0"
}
}
}
It generates the .aar file, the pom.xml, etc without problems.
Then I create a project that have a dependeny to my library declared. It works until it needs to access to the external dependencies, when throws a class not found exception.
How can I edit my gradle task to include external dependencies or at least a reference to them? They are published in mvnrepository.com and github.com.

I moved uploadArchives to the build.gradle of the module and removed the artifacts element. It works!
Thanks to CommonsWare for pointing to the right direction.

Is there Gradle "dependencies " task for buildScript dependencies?

One can run gradlew dependencies to learn about dependencies of module tasks. It there a way to find transitive dependencies of buildscript dependencies?
Example:
classpath 'com.android.tools.build:gradle:1.0.0' depends directly on:
com.android.tools.build builder
com.android.tools.lint lint
net.sf.proguard proguard-gradle
tools.base project-test-lib
As can be seen on MVNRepository. But this artifacts have their own dependencies. Is there and way to find those out without manually traversing whole dependency tree?
As a clarification, the classpath I'm talking about is defined by:
buildscript {
repositories {}
dependencies { .... }
}

Beginning with Gradle 2.10 you can now get information on buildscript dependencies via
gradle buildEnvironment
With older versions you'll have to explicitly define a task of type DependencyReportTask configured with your build script configuration.
task buildscriptDependencies(type: DependencyReportTask) {
configurations = [buildscript.configurations.classpath]
}

I think you're looking for Gradle's DependencyInsightReportTask

You can use this command:
gradle dependencyInsight --dependency gradle
There is awesome tutorial by Udacity, Gradle for Android, but you can watch this video for more explanation.
