Netbeans/gradle/java not loading jackson or snakeyaml

I’m trying to develop a JavaFX application using Java 13 that will use YAML. I would like to use SnakeYAML but I’m getting the following error from Apache Netbeans 11.2…

EDAmame has some issues

  • Could not resolve all files for configuration ‘:compileClasspath’.
    Could not resolve org.yaml:snakeyaml:1.25
    Required by:
    project:
  • Could not resolve all files for configuration ‘:testCompileClasspath’.
    Could not resolve org.yaml:snakeyaml:1.25
    Required by:
    project:

Which is just short of meaningless to me and I can’t seem to get any other log information out of Netbeans. It also then interferes with finding the javafx stuff as well. What did I do wrong?

If I switch to a maven project and use the same depoendency information (formatted for Maven) then either SnakeYAML or jackson import just fine. But gradle seems unable to import either jackson or SnakeYaml.

My build.gradle:
plugins {
id ‘application’
id ‘org.openjfx.javafxplugin’ version ‘0.0.8’
}

apply plugin: ‘java’
apply plugin: ‘jacoco’
apply plugin: ‘application’

group = ‘com.cyte’

mainClassName = ‘com.cyte.EDAmame.EDAmame’

repositories {
jcenter()
}

dependencies {
testCompile ‘junit:junit:4.12’
compile ‘org.yaml:snakeyaml:1.25’
}

javafx {
version = “13.0.1”
modules = [ ‘javafx.controls’, ‘javafx.fxml’ ]
}
