Gradle plugin dependency problem

[Lennart Börjeson]

Is this the right place to ask questions on the gradle plugin (org.openjfx.javafxplugin) ?

I'm trying to migrate to Java 11 and openjfx. I have a gradle setup with multiple projects, which seems to be problematic.

Base: Mostly non-GUI, code but still some references to javafx
GUI: The javafx GUI, depends on Base
Release: Release artefact packaging, depends on both Base and GUI.

The basic problem seems to be I can't use the org.openjfx.javafxplugin in a project which another projects depends on, since the plugin apparently injects the javafx library artefacts *after" the configuration phase.


The relevant section of my build.gradle in the Base project is:


---BEGIN----------

plugins {
  id 'java'
  id 'maven'
  id 'application'
  id 'wrapper'
  id 'eclipse'
  id "me.champeau.gradle.jmh" version '0.4.6'
  id 'org.openjfx.javafxplugin' version '0.0.5'
}

javafx {
    modules = [ 'javafx.controls' ]
}

--END-------------


If I remove the javafx section, the gradle can execute, but my project won't build. :-(

(I can't resolve this by moving all javafx usage to the GUI project, since the Release project (release artefact packaging) would still depend on GUI.)


Cf. error below:





$ ./gradlew build
