我正在使用gradle 8为一个多模块项目编写构建脚本。0.2，在库中声明一些依赖关系。我的构建脚本如下所示

buildscript {
    repositories {
        gradlePluginPortal()
        maven {
            url = uri("https://plugins.gradle.org/m2/")
        }
    }
    dependencies {
        classpath("gradle.plugin.com.github.johnrengelman:shadow:7.1.2")
    }

}

plugins{
    `kotlin-dsl`
}

group = "xxx"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_19

subprojects {
    apply(plugin = "java")
    apply(plugin = "checkstyle")
    apply(plugin = "maven-publish")
    apply(plugin = "com.github.johnrengelman.shadow")
    // common deps + repos
    repositories {
        mavenCentral()
    }

    dependencies {
        api(libs.jsr305)
        testImplementation(libs.bundles.junit)

        compileOnly(libs.lombok)
        annotationProcessor(libs.lombok)

        testCompileOnly(libs.lombok)
        testAnnotationProcessor(libs.lombok)
    }

    java {
        withSourcesJar()
    }

    tasks.named<Test>("test") {
        useJUnitPlatform()
    }

    tasks.withType<JavaCompile>() {
        options.encoding = "UTF-8"
    }

    tasks.withType<Javadoc>() {
        options.encoding = "UTF-8"
    }
}

我想在每个子项目中应用这些常见的依赖项，这些依赖项在库中定义。toml，我可以保证libs。toml的编写没有问题，但是我不能让它在子项目中工作
