How does one combine ScalaFXML with Gradle? - scala

Question

Let me set up my end goal first:
I want to build a scala only gui application, that I can design with scene builder and later port with gluon to any platform I want to.
I was able to find out, that one needs to use JavaFXPorts in Scala to make that happen. I also found out that I need to use gradle to apply gluon successfully, or so it seems (please correct me if I am wrong because that's where the headache starts)
So in short that means: ScalaFXML and Gradle need to work together, but how?
I've found some interesting projects, but sadly none of these hit my criteria just right:
This one used JavaFX instead of ScalaFX
This one added Java to the project instead of using pure scala
After a long time searching I found a project, that was almost right. Sadly, this was built in sbt and not in gradle.
None the less I used that project as a base/example, as this was the first to use sfxml in way that was easily understood.
I have a gradle script, that almost works
buildscript {
repositories {
mavenLocal()
jcenter()
}
dependencies {
// during build, we depend on the jfxmobile-plugin
classpath 'org.javafxports:jfxmobile-plugin:1.3.10'
}
}
plugins {
id 'java'
id 'scala'
id 'application'
}
apply plugin: 'org.javafxports.jfxmobile'
configurations {
scalaCompiler
scalaCompilerPlugin
}
configurations.scalaCompiler.transitive = false
compileScala.targetCompatibility = "1.8"
mainClassName = 'sfxml.Main'
repositories {
mavenCentral()
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
dependencies {
compile 'org.scala-lang:scala-library:2.12.6'
compile 'org.scala-lang:scala-compiler:2.12.6'
compile 'com.gluonhq:particle:1.1.3'
compile group: 'org.scalafx', name: 'scalafx_2.12', version: '8.0.144-R12'
compile group: 'org.scalafx', name: 'scalafxml-core-sfx8_2.12', version: '0.4'
compile group: 'org.scalamacros', name: 'paradise_2.12.6', version: '2.1.1'
scalaCompiler "org.scalamacros:paradise_2.12.6:2.1.1"
testCompile group: 'junit', name: 'junit', version: '4.12'
}
tasks.withType(ScalaCompile) {
scalaCompileOptions.additionalParameters = [
"-Xplugin:" + configurations.scalaCompilerPlugin.asPath,
"-Ymacro-debug-lite"
]
options.compilerArgs = ["-Xdebug", "-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=9999"]
}
After finally finding all the right repositories (or so I thought) no errors were marked down during the import process from IDEA, but at last I got the following error:
Error:(10, 7) macro annotation could not be expanded (the most common reason for that is that you need to enable the macro paradise plugin; another possibility is that you try to use macro annotation in the same compilation run that defines it)
class AdoptionFormPresenter(private val sizeTextField: TextField,
But as you might have figured out - if you've read the gradle script - I already tried enabling the plugin. So how do I fix this and achieve the goal stated at the beginning?
Btw: I already found the following solutions, but those also didn't work
This uses maven, but I want to use gradle, soo... thx google?
This sadly doesn't work
This sadly... also does not work :/

Answer 1

So after revisiting my gradle script and checking against the previously mentioned work arrounds, I found my mistake.
I didn't include the complete answer from here. So after editing my build.gradle to only include the necessary things, I got the following:
plugins {
id 'java'
id 'scala'
}
apply plugin: 'org.javafxports.jfxmobile'
configurations {
scalaCompiler
}
configurations.scalaCompiler.transitive = false
compileScala.targetCompatibility = "1.8"
repositories {
mavenCentral()
jcenter()
}
dependencies {
compile 'org.scala-lang:scala-library:2.12.6'
compile group: 'org.scalafx', name: 'scalafx_2.12', version: '8.0.144-R12'
compile group: 'org.scalafx', name: 'scalafxml-core-sfx8_2.12', version: '0.4'
scalaCompiler "org.scalamacros:paradise_2.12.6:2.1.1"
testCompile group: 'junit', name: 'junit', version: '4.12'
}
def String scalaCompilerOptions="-Xplugin:$configurations.scalaCompiler.singleFile.path"
compileScala.scalaCompileOptions.additionalParameters = [scalaCompilerOptions]
compileTestScala.scalaCompileOptions.additionalParameters = [scalaCompilerOptions]
That script will run this project with gradle instead of sbt.
Side note:
If you get the error "Cannot load resource: AdoptionForm.fxml" read the following post
I didn't complete my previously stated goal just yet, since I haven't used gluon for now. But the main problem of this post is solved, so I will mark this as the right answer.
I might add the gluon integration later if I get it to work.
