I am attempting to startup a gRPC client with JavaFX, but when I try to run it, I get the following message

> Cannot choose between the available variants of org.openjfx:javafx-controls:23.0.1:
          - linux-aarch64Runtime
          - linuxRuntime
          - mac-aarch64Runtime
          - macRuntime
          - runtime
          - winRuntime

I have been at this all day and cannot figure out for the life of me what's going on. I have tried all kinds of things. My latest attempt includes running this bit of code in my build.gradle file in the hopes of pointing explicitly to the location of the JavaFX installation to avoid any ambiguity:

def javafxHome = System.getenv('JAVAFX_HOME')
tasks.withType(JavaCompile).configureEach {
    options.encoding = 'UTF-8'
    options.fork = true
    options.compilerArgs.addAll(['-Xlint:deprecation','-Xlint:unchecked','-Xlint:preview'])
    options.compilerArgs.addAll(['--module-path',javafxHome+File.separator+'lib'])
    sourceCompatibility='23'
    targetCompatibility='23'
}

I have of course already added these plugins:

plugins {
    id('java')
    id("application")
    id('idea')
    id("com.github.johnrengelman.shadow") version "8.1.1"
    id("io.micronaut.application") version "4.4.4"
    id("com.google.protobuf") version "0.9.2"

    id("org.openjfx.javafxplugin") version "0.1.0"
}

javafx {
    version = "23.0.1"
    modules = [ 'javafx.controls', 'javafx.graphics', 'javafx.base' ]
}

Is anyone able to shed any light on this? I am confounded.

ah the javafx thing is superspecial and doesnt work very well. so the javafx block also has a configurations block where you need to configure on which configurations it actually runs. The configuration name that fails should be somewhere in the error message

Hey @TheGoesen This is what I see:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to <https://docs.gradle.org/8.11.1/userguide/command_line_interface.html#sec:command_line_warnings> in the Gradle documentation.

Could not resolve all files for configuration ':compileProtoPath'.

JavaFX is on the protobuf classpath for some reason. This is a "special" configuration the JavaFX plugin does not know about. Maybe this can be avoided. But the Protobuf plugin is also doing some very special things. It always seems to be a fight with that one.... You can set additional attributes for the

compileProtoPath

configuration to resolve the variant conflict. Similar to what is done here for the normal classpaths: https://github.com/openjfx/javafx-gradle-plugin/blob/master/src/main/java/org/openjfx/gradle/JavaFXOptions.java#L109-L114 Something like:

configurations.compileProtoPath {
  attributes {
    attribute(OperatingSystemFamily.OPERATING_SYSTEM_ATTRIBUTE,
                objects.named(OperatingSystemFamily, javafx.platform.osFamily));
    attribute(MachineArchitecture.ARCHITECTURE_ATTRIBUTE,
                objects.named(MachineArchitecture, javafx.platform.arch));
  }
}

I think there is no shortcut for this in the

javafx { }

block at the moment.

you can really just set the configurations it runs in in the javafx block: https://github.com/openjfx/javafx-gradle-plugin/blob/master/src/main/java/org/openjfx/gradle/JavaFXOptions.java But usually javafx should not end up in the protobuff classpath at all. Also sad news even if you can figure that one out, the javafx plugin will break the configuration cache if you you use run

Looking at the errors again: • The first one does not show which configuration is failing - maybe it is somewhere else and not protobuf • The second error complains about missing repositories. There, something else must be broken in the setup.

Thanks, guys. I would have accidentally deleted the repositories. I restored it, but I'm still getting this ambiguity error. Now, instead of ":compileProtoPath" I am getting ":developmentRuntimeClasspath":

I think

developmentRuntimeClasspath

is probably something out of the micronaut plugin. It makes more sense that that has JavaFX. Still that one is "special". You should be able to apply what I posted to that one.

Thank you all. I got this over this hurdle thanks to you!
