已添加正确依赖仍无法引用org.springframework.data.redis的问题

我是IntelliJ/Kotlin新手，在.kts文件中配置了Spring Boot相关依赖（包含spring-boot-starter-data-redis等），但在Main.java中导入org.springframework.data.redis.core.RedisHash和org.springframework.data.redis.core.index.Indexed时，IDE无法识别redis相关包，显示“unresolved reference to redis”，请问哪里操作有误？

我的.kts配置代码：

plugins {
    id("java")
    id("io.spring.dependency-management") version "1.0.12.RELEASE"
    id("org.springframework.boot") version "2.7.0"
}

group = "org.example"
version = "1.0-SNAPSHOT"

repositories {
    google()
    mavenLocal()
    maven( "https://jitpack.io" )
    maven("https://maven.aliyun.com/repository/google/")
    maven("https://maven.aliyun.com/repository/public/")
    maven("https://maven.aliyun.com/repository/spring/")
    maven("https://maven.aliyun.com/repository/gradle-plugin/")
    maven("https://maven.aliyun.com/repository/spring-plugin/")
    mavenCentral()
    maven("https://plugins.gradle.org/m2")
}

dependencies {
    //https://medium.com/@krishnan.srm/springboot-kotlin-and-redis-great-partners-9207fe79c329
    implementation("org.springframework.data:spring-data-commons")
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation("org.springframework.boot:spring-boot-starter-data-redis")
    implementation("org.springframework.boot:spring-boot-starter-web")

    implementation("org.springframework.data:spring-data-redis:2.7.0")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")

    //implementation("org.jetbrains.kotlin:kotlin-gradle-plugin")

    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-mustache")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")      
}

问题主要出在依赖重复、冗余依赖以及插件配置不全这几个点，按以下步骤修复：

1. 清理重复和冗余依赖

   • 删除重复的spring-boot-starter-web和jackson-module-kotlin依赖项，每组只保留一个
   • spring-boot-starter-data-redis已经包含了spring-data-redis，且Spring Boot的依赖管理插件会自动控制版本，无需手动添加org.springframework.data:spring-data-redis:2.7.0，直接删除该行

2. 补充Kotlin插件
   作为Kotlin项目，需要添加Kotlin JVM插件，在plugins块中加入：

   id("org.jetbrains.kotlin.jvm") version "1.6.21"
   

   （版本号选择与Spring Boot 2.7.0兼容的1.6.x系列即可）

3. 修改后的完整配置

plugins {
    id("java")
    id("org.jetbrains.kotlin.jvm") version "1.6.21"
    id("io.spring.dependency-management") version "1.0.12.RELEASE"
    id("org.springframework.boot") version "2.7.0"
}

group = "org.example"
version = "1.0-SNAPSHOT"

repositories {
    google()
    mavenLocal()
    maven( "https://jitpack.io" )
    maven("https://maven.aliyun.com/repository/google/")
    maven("https://maven.aliyun.com/repository/public/")
    maven("https://maven.aliyun.com/repository/spring/")
    maven("https://maven.aliyun.com/repository/gradle-plugin/")
    maven("https://maven.aliyun.com/repository/spring-plugin/")
    mavenCentral()
    maven("https://plugins.gradle.org/m2")
}

dependencies {
    implementation("org.springframework.data:spring-data-commons")
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation("org.springframework.boot:spring-boot-starter-data-redis")
    implementation("org.springframework.boot:spring-boot-starter-web")

    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")

    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-mustache")
}

4. 同步Gradle并刷新IDE
   • 在IntelliJ右侧Gradle面板点击刷新按钮（🔄），或者执行命令：./gradlew clean build --refresh-dependencies
   • 若仍有问题，尝试执行File -> Invalidate Caches... -> Invalidate and Restart重置IDE缓存
