Plugin error on importing gradle project into another

I am from Maven background and very new to Gradle. Given below is the context.

I have a library project

LibraryStarter

which needs to be imported to a

LibraryUser

project.

Both are spring boot projects and the build.gradle of LibraryUser complains that

Could not run phased build action using Gradle distribution 'https://services.gradle.org/distributions/gradle-6.6.1-bin.zip'. Build file 'C:\WORK\LEARN\User\LibraryStarter\build.gradle' line: 2 Error resolving plugin [id: 'org.springframework.boot', version: '2.3.4.RELEASE'] Plugin request for plugin already on the classpath must not include a version

I tried to apply the suggestion, but did not helped.

Keeping both the build.gradle files for reference.

For LibraryStarter

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



group = 'com.sample.library.starter'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'


repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation project(":MyLibrary")
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

test {
    useJUnitPlatform()
}

For LibraryUser

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

group = 'com.sample.library.user'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation project(":LibraryStarter")
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

test {
    useJUnitPlatform()
}

Any help will be much appreciated.

#################### UPDATE #################

Updated the build.gradle as requested by @Onur in comments. But the spring dependencies are removed from classpath and caused compilation errors in classes.

apply plugin: 'java'

group = 'com.sample.library.user'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation project(":LibraryStarter")
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
}

test {
    useJUnitPlatform()
}

###################### UPDATE ########################

I got it working. But not sure if I am doing it right.

Removed the plugins from the LibraryStarter and added the following dependencies.

implementation group: 'org.springframework', name: 'spring-context', version: "${spring_version}" implementation group: 'org.springframework.boot', name: 'spring-boot-autoconfigure', version: "${springboot_version}" implementation group: 'org.springframework.cloud', name: 'spring-cloud-context' implementation group: 'org.springframework.cloud', name: 'spring-cloud-commons'

If you think this is the right approach, I can post it as an answer. Else I am still open for your suggestions.

Keen to know the best and valid approach to handle this situation, rather than applying any patch!.

if your module structure is like

root (LibraryUser)
 |__build.gradle
 |__sub-project (LibraryStarter)
    |__build.gradle

then in the root build.gradle

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

allprojects {
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'org.springframework.boot'
}

Do not add (remove) plugins section in the sub-projects
