gradle项目a模块引用b模块，类可以导包成功，但springboot启动则失败

问题遇到的现象和发生背景

gradle创建父子模块进行项目引用，不引用‘service’模块可以启动，引用则启动报找不到类

问题相关代码，请勿粘贴截图

‘app’模块gradle代码

repositories {
    mavenCentral()
}
dependencies {
    implementation  project(':service')
}

‘service’模块gradle代码

repositories {
    mavenCentral()
}
jar.enabled=true
bootJar.enabled=false

运行结果及报错内容

Description:

Field testService in com.tianliang.app.controller.HelloController required a bean of type 'com.tianliang.service.service.TestService' that could not be found.


Action:

Consider defining a bean of type 'com.tianliang.service.service.TestService' in your configuration.

我的解答思路和尝试过的方法

我想要达到的结果

gradle 6.7.1
父级build.gradle

plugins {
    id 'org.springframework.boot' version '2.0.2.RELEASE'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

// 构建配置
ext {
    java_version = '1.8'
    spring_boot_version = '2.0.2.RELEASE'
    spring_gradle_plugin_version = '1.0.11.RELEASE'
}

//该项目与全部子项目的属性
allprojects {
    group='com.tianliang'
    version='0.0.1-SNAPSHOT'
    //仓库,国内外仓库访问、下载速度会不同
    repositories {
        mavenLocal()
        maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
        mavenCentral()
    }
}


subprojects {
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'java'

    sourceCompatibility = java_version
    targetCompatibility = java_version

    tasks.withType(JavaCompile) {
        options.encoding = 'UTF-8'
    }

    dependencies {
        implementation 'org.springframework.boot:spring-boot-starter-web'
        testImplementation 'org.springframework.boot:spring-boot-starter-test'
    }

    test {
        useJUnitPlatform()
    }

}

问题已解决。gradle设置的group之后，项目名称不要有多余层级
