Not able to reference other modules inside gradle project in intelij

I have created a relatively new project with 4 modules inside one project (created with intelij). However, I have now got to the stage where I want to import one module (:domain) from another (app-updater). The issue I'm facing is when I do this from within intelij it gives me errors in the "Build: Sync" tab. This is strange since my module app-updater is able to reference to module domain when I add the line "compile project(':domain')" into build.gradle and when I remove the line I get issues with the class being missing so the build: sync seems to be working it's just running it from inside intelij seems to give an error saying "Project with path ':domain' could not be found in root project 'app-updater'." I have attached my gradle config below, hopefully I have given enough info but if not feel free to ask for more, thanks for any help.
Main project settings.gradle file
rootProject.name = 'rGuide'
include 'domain'
include 'service'
include 'app-updater'
include 'app-rest'
:domain build.gradle
group 'domain'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
// https://mvnrepository.com
compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.0.1'
compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.9'
compile group: 'commons-lang', name: 'commons-lang', version: '2.6'
testCompile group: 'junit', name: 'junit', version: '4.12'
}
app-updater build.gradle file
group 'app-updater'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
google()
maven {
url 'https://repo.spring.io/plugins-release/'
}
maven {

}
}
dependencies {
compile project(':domain')
// https://mvnrepository.com
compile group: 'net.ser1', name: 'gozirra-client', version: '0.4.1'
compile group: 'io.netty', name: 'netty-all', version: '4.1.36.Final'
compile group: 'io.projectreactor.netty', name: 'reactor-netty', version: '0.9.0.M2'
compile group: 'org.springframework.integration', name: 'spring-integration-stomp', version: '5.1.6.RELEASE'
compile group: 'org.springframework.integration', name: 'spring-integration-core', version: '5.1.6.RELEASE'

compile group: 'com.fasterxml.jackson.core', name: 'jackson-core', version: '2.9.9'
testCompile group: 'junit', name: 'junit', version: '4.12'
}
TLDR - Trying to import domain into app-updater within intelij, it "works fine" and seems to import domain however when I do this with the Build: sync tab in intelij it gives an error saying "Project with path ':domain' could not be found in root project 'app-updater'.". Thanks for any help!!

Java 8 intellij and gradle fat jar wont find configuration files and enableautoconfiguration

I am trying to build fat jar, but the jar is giving me error. I have built fat jar before with javaFx 11 and java 11. Now I am using Java 8 and Spring I am doing it with intellij from File>Project Structure>Artifacts, there I choose ProjectRoot main module and then also add my resources directory content and I build the jar.

My RestaurantAplication.class is was in my restaurant folder, but I read somewhere that it should be above my package with my classes, so I moved it to the projectId folder, but it didn't work.
My main:
#SpringBootApplication
#EnableScheduling
#EnableConfigurationProperties
public class RestaurantApplication {
public static void main(String[] args) {
SpringApplication.run(RestaurantApplication.class, args);
}
}
Edit: in the jars's spring.factories in the META-INF folder there is only one line:
org.springframework.beans.BeanInfoFactory=org.springframework.beans.ExtendedBeanInfoFactory
I tried adding them to the file also adding some of the ones listed in the error and also my config files:
org.springframework.beans.BeanInfoFactory=org.springframework.beans.ExtendedBeanInfoFactory
org.springframework.boot.autoconfigure.AutoConfigurationImportSelector
org.springframework.context.annotation.ConfigurationClassParser
com.projectId.restaurant.config.AppConfig
com.projectId.restaurant.config.PasswordEncoderConfig
com.projectId.restaurant.config.ScheduleConfig
com.projectId.restaurant.config.Scheduler
com.projectId.restaurant.config.SecurityConfig
But even then the lines in the error still exist for the exact configurations I have added:

add this below lines into your build.gradle
jar { manifest {attributes "Main-Class": "your main class" } from {configurations.compile.collect { it.isDirectory()? it : zipTree(it) } }
then do a clean/build,
the jar created in \build\libs folder is your runnable jar

I am so confused as to why I can run it in IDE but not as a jar. Also I found out that my jar doesn't contain any libraries at all.
EDIT:
This is my Application.class
package some.application;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class Application
{
public static void main(String[] args)
{
SpringApplication.run(Application.class, args);
}
}

This is because your dependencies are not included into the end jar file.
Take a look on the examples here or here.
Or alternatively use ./gradlew clean build that should automatically pack the app correctly. Take a look on the official guide

Define a task called fatJar in build.gradle:
jar {
baseName = 'base-name'
version = '0.1.0'
manifest {
attributes(
'Main-Class': 'com.github:'
)
}
}
task fatJar(type: Jar) {
manifest.from jar.manifest
// classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
artifacts {
archives fatJar
}
Run gradle fatJar or ./gradlew fatJar to generate a jar file with all dependencies, which can run independently but may be pretty large in size (that's why it's called a fat jar).
