Access dot property stored in gradle.properties within settings.gradle

Question

I have a Gradle 6.0.1 project. The build.gradle (excerpt) looks like:

plugins {
  id "application"
  id "com.github.edeandrea.xjc-generation"
  id "eclipse"
  id "idea"
  id "java"
  id "org.springframework.boot"
}

...

dependencies {
  implementation platform("org.springframework.boot:spring-boot-dependencies:${property("spring-boot.version")}")

  // ...more stuff here
}

// ...more stuff here

I'm managing all the plugin versions in settings.gradle:

pluginManagement {
  plugins {
    id "application"
    id "com.github.edeandrea.xjc-generation" version "1.0"
    id "eclipse"
    id "idea"
    id "java"
    id "org.springframework.boot" version "${spring-boot.version}"
  }
}

rootProject.name = "spring-core"

...and I usually put the artifact versions in gradle.properties:

#
# Dependency Versions
oracle.version = 18.3.0.0
spring-boot.version = 2.2.1.RELEASE

#
# Gradle Settings
org.gradle.configureondemand = false
org.gradle.daemon = false

#
# System Settings
systemProp.file.encoding = UTF-8
systemProp.sun.jnu.encoding = UTF-8

Now the problem is I can't read dot-properties in settings.gradle (from gradle.properties) in the same way I do it inside build.gradle — I already tried using ${property("spring-boot.version")}.

Is there any way to achieve that? I can easily change the key to something like springBootVersion and it works, but I wonder if there is a way to have in the way I currently have it: spring-boot.version.

use getProperty("spring-boot.version")

---

simple gradle project with additional variants

task test{
    doLast {
        //success
        println project.property('aaa.bbb.ccc')
        println project.'aaa.bbb.ccc'
        println getProperty('aaa.bbb.ccc')

        //failure: Could not get unknown property 'aaa.bbb.ccc' for task ':test' of type org.gradle.api.DefaultTask
        println property('aaa.bbb.ccc') 
    }
}

gradle.properties

aaa.bbb.ccc=12345

property('aaa.bbb.ccc') fails because it tries to get property on current object (task) but aaa.bbb.ccc defined for project

however project.property('aaa.bbb.ccc') succeeds because it should

project.'aaa.bbb.ccc' is the same as project.getProperty('aaa.bbb.ccc') in groovy

project.getProperty('aaa.bbb.ccc') works because of groovy basic object GroovyObject (IHMO)

and getProperty(name) without prefix actualy located in org.gradle.groovy.scripts.BasicScript and not really documented...
