Answer 1

The question is about "Adding"; the question of the text is describing a more concrete scenario. If one just wants to add an existing directory, this is the way to add:

sourceSets.main.java.srcDirs += ['src/gen/java']

An example full build.gradle is as follows:

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'com.squareup:javapoet:1.12.1'
}

sourceSets.main.java.srcDirs += ['src/gen/java']

JavaPoet s a Java API for generating .java source files. It is just used as example library for the build.gradle file.
