How to get Azure Pipelines to recognize JavaFX dependency with Gradle

Question

I have been unable to get Azure Pipelines to run the way I am expecting.

The project codebase is in Java, version 8 and is using the JavaFX Library.

I am trying to introduce continuous integration via Azure Pipelines. To do this I decided to use Gradle to manage project dependencies.

Here is the gradle.build file I am using to declare project dependencies.

/*
 * This file was generated by the Gradle 'init' task.
 *
 * This generated file contains a sample Java project to get you started.
 * For more details take a look at the Java Quickstart chapter in the Gradle
 * User Manual available at https://docs.gradle.org/6.1.1/userguide/tutorial_java_projects.html
 */

plugins {
    // Apply the java plugin to add support for Java
    id 'java'

    // Apply the application plugin to add support for building a CLI application.
    id 'application'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    mavenLocal()
    mavenCentral()
    jcenter()
}

dependencies {
    // This dependency is used by the application.
    implementation 'com.google.guava:guava:28.1-jre'
    implementation 'de.dynamicfiles.projects.gradle.plugins:javafx-gradle-plugin:8.8.2'

    // Use JUnit Jupiter API for testing.
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.5.2'

    // Use JUnit Jupiter Engine for testing.
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.5.2'
}

application {
    // Define the main class for the application.
    mainClassName = 'main.java.application.App'
}

test {
    // Use junit platform for unit tests
    useJUnitPlatform()
}

This is the error I except when I run my pipeline. This is a run from my computer.

Here is the error I am getting in when I run the pipeline. This is a run in a Microsoft hosted VM.

So the issue is that in the Pipeline it's throwing an error saying that a JavaFX import does not exist. When in theory

./gradle build

should be installing the required libraries on the Microsoft VM to run the code.

Just in case anyone is interested here is my azure-pipelines.yaml

trigger:
  - master

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: Gradle@2
  inputs:
    gradleWrapperFile: 'Anature/gradlew'
    workingDirectory: 'Anature'
    options: '--refresh-dependencies' 
    tasks: 'build'
    publishJUnitResults: true
    testResultsFiles: '**/TEST-*.xml'
    javaHomeOption: 'JDKVersion'
    jdkVersionOption: '1.8'
    sonarQubeRunAnalysis: false

Here you can see I am trying to force install all the dependencies but still am getting a

package javafx.scene.image does not exist

Here are some reference links:

For Azure Gradle task. https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/build/gradle?view=azure-devops

Azure VM Specs: https://github.com/actions/virtual-environments/blob/master/images/linux/Ubuntu1804-README.md

Gradle dependency information: https://docs.gradle.org/current/userguide/declaring_dependencies.html

Update:

I had to first figure out what an azure pipeline VM had stock on it and why JavaFX wasn't working.

Here is a link to the download Java 1.8 version that comes stock on the Azure VM.

http://repos.azul.com/azure-only/zulu/packages/zulu-8/8u222/

Once you download the Zulu package for java you will see that JavaFX was not apart of the Java download like it is for the Java JDK.

Please try to set system.debug to True and share the entire log. — Cece Dong - MSFT, Feb 10 '20 at 10:18
@HunterMatthewRich Have you tried to install `openjfx`? Is it working? — Cece Dong - MSFT, Feb 19 '20 at 10:03
@CeceDong-MSFT I will try that this week. I was doing some research on what comes stock on the VM and will update my post with my findings later this week as well. — Hunter Matthew Rich, Feb 19 '20 at 19:29
@HunterMatthewRich Is your issue solved after you use chocolatey to install the java jdk and switch to windows-latest VM? — Cece Dong - MSFT, Mar 03 '20 at 06:03

You may try to install openjfx to see whether the issue persists:

sudo apt-get install openjfx

I was not able to get that to work. I think it might be a Path variable problem. Since the previous Java 1.8 bin is still in the Path. I am using chocolatey to install the java jdk instead of the openjfx and I have switched to windows-latest VM instead of using ubuntu. – Hunter Matthew Rich Feb 23 '20 at 21:43

I had the same problem, this is what worked for me.

Install chocolatey from Azure MarketPlace
Add chocolatey as task to install jdk8
Add PS Task with the commands below to adjust path variables

´´´

$newpath = “C:\Program Files\Java\jdk1.8.0_211”
Write-Host "##vso[task.setvariable variable=PATH;]${env:PATH};$newPath";
Write-Host "##vso[task.setvariable variable=JAVA_HOME;]$newPath";
Write-Host "##vso[task.setvariable variable=JDK_18_x64;]$newPath";

´´´

The persistent change of the environment variables is a bit of a pain because there is a lot of information around that just does not help in this scenario. What finally helped me was this post here:

Set "Path" environment variable during vsts build so it would persist across build tasks specifically vsTest task
