Gradle multi-project repository configuration not working for spring-boot application

I have a simple multi-project structure as follows:

|- gps-framework
|- build.gradle
|- settings.gradle
|- gps-web-service
|----build.gradle
|----src/main....

Under the root build.gradle located in gps-framework/ looks like this:

plugins {
id 'java'
id "java-library"
id "maven-publish"
id "jacoco"
id 'org.springframework.boot' version '2.3.4.RELEASE'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
}
subprojects {
subproject ->
apply plugin: 'maven-publish'
apply plugin: 'jacoco'
def isApp = subproject.name == 'gps-web-service'
if (isApp) {
apply plugin: 'java'
} else {
apply plugin: 'java-library'
}
group = 'com.mycompnay'
version = project.hasProperty('customVersion') ? project['customVersion'] : 'integration-SNAPSHOT'
//System.out.println(subproject.name)
compileJava {
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
options.encoding = 'UTF-8'
}
compileTestJava {
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
options.encoding = 'UTF-8'
}
repositories {
mavenCentral()
mavenLocal()
maven {
name "release"
url "my-custom-mvn-repo/release"
authentication {
//
}
}
maven {
name "snapshot"
url "my-custoom-mvn-repo/snapshot"
authentication {
//
}
}
}
configurations {
runtime.exclude(group: "org.slf4j", module:"slf4j-log4j12")
}
publishing {
repositories {
maven {
authentication {
//
}
def isSnapshot = subproject.version.contains('SNAPSHOT')
url =  isSnapshot ? "my-custom-mvn-repo/snapshot" : "my-custom-mnv-repo/release"
}
}
}
jacocoTestReport {
reports {
xml.enabled true
html.enabled true
}
}
if (subproject.hasProperty('jacocoTestCoverageVerification')) {
subproject.check.dependsOn subproject.jacocoTestCoverageVerification
}
test {
testLogging {
exceptionFormat = 'full'
}
}
}

The build.gradle of sub-project gps-web-service located in gps-framework/gps-web-service looks like this:

group = 'com.mycompany'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
test {
useJUnitPlatform()
}

From what I have read so far, since the repository settings are defined in the root build.gradle and these settings are injected into these subprojects, I do not need to redefine repository settings. This does not appear to be the case as when I run

./gradlew build

The error I get is:

Could not find org.springframework.boot:spring-boot-starter-web:.
Required by:
project :gps-web-service
Possible solution:
- Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

Am I misunderstanding the whole concept of injection of project properties or what am I missing here? I will try duplicating the repo settings in the sub-projects build.gradle but was hoping this is not necessary.

To solve this specific problem, I had to define the spring boot plugin in the sub-project's build.gradle as follows:

plugins {
id 'org.springframework.boot' version '2.3.4.RELEASE'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
}

The resulting file looks like this:

plugins {
id 'org.springframework.boot' version '2.3.4.RELEASE'
id 'io.spring.dependency-management' version '1.0.10.RELEASE'
}
group = 'com.mycompany'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
test {
useJUnitPlatform()
}
