Spring Boot 3 Gradle 构建在 IntelliJ Idea 2023.2 中失败

Question

Gradle 构建失败。

构建.gradle：

plugins {
    id 'java'
    id 'war'
    id 'org.springframework.boot' version '3.1.2'
    id 'io.spring.dependency-management' version '1.1.2'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '17'
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
    maven { url 'https://repo.spring.io/milestone' }
    maven { url 'https://repo.spring.io/snapshot' }
    gradlePluginPortal()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-web'

    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

tasks.named('test') {
    useJUnitPlatform()
}

我还在项目结构中检查了 JVM 依赖性。这里我设置的是JDK-17

Answer 1

要将 JDK 17 用于 Gradle 包装器，请将 IDE 设置配置为使用 JDK 17，而不是在项目结构中设置 JDK 版本。
