Where is build folder in root project folder?

Hi! I am using gradle 6.8.3. I have some build.gradle in packages, and he create build folder there so like this:

Summary

RootProjectFolder

         |
         ----  somefolder1
         |              |
         |                -------- build (folder from gradle)
         |                -------- somefolderwithsources
         |
         ---- somefolder2
                         |
                         -------- build (folder from gradle)
                         -------- somefolderwithsources

So my question is, where is the folder, i saw somewhere that RootProjectFolder had build folder, so the model will be like this:

Summary

RootProjectFolder

         |
         -------- build (folder from gradle)    <--------- How to tell gradle to create this?
         |
         ----  somefolder1
         |              |
         |                -------- build (folder from gradle)
         |                -------- somefolderwithsources
         |
         ---- somefolder2
                         |
                         -------- build (folder from gradle)
                         -------- somefolderwithsources

In build.gradle from root folder, i have some configs, so one of them is this
xml.destination file("${buildDir}/jacoco.xml")
so jacoco.xml need to be created in rootfolder->buildfolder->jacoco.xml
And other config, i run this in allprojects {
group = ‘com.somecompany.someprojname.somesubname’
version = ‘1.1.1-SNAPSHOT’
sourceCompatibility = 11
targetCompatibility = 11
compileJava.options.encoding = ‘UTF-8’
compileTestJava.options.encoding = ‘UTF-8’

Gradle will create the declared output directory of a task when execution of that task starts. You don’t need to tell Gradle to create that folder. It will be created automatically if your task outputs are properly configured.
