解决 Spring Boot 和 Gradle Java 版本兼容性问题:A problem occurred configuring root project ‘demo1’.

Could not resolve all files for configuration ‘:classpath’.

A problem occurred configuring root project ‘demo1’.

Could not resolve all files for configuration ‘:classpath’.

Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.1.3.

Required by:

project : > org.springframework.boot:org.springframework.boot.gradle.plugin:3.1.3

No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.1.3 was found. The consumer was configured to find a library for use during runtime, compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute ‘org.gradle.plugin.api-version’ with value ‘8.2.1’ but:

- Variant ‘apiElements’ capability org.springframework.boot:spring-boot-gradle-plugin:3.1.3 declares a library, packaged as a jar, and its dependencies declared externally:

- Incompatible because this component declares a component for use during compile-time, compatible with Java 17 and the consumer needed a component for use during runtime, compatible with Java 8

- Other compatible attribute:

- Doesn’t say anything about org.gradle.plugin.api-version (required ‘8.2.1’)

- Variant ‘javadocElements’ capability org.springframework.boot:spring-boot-gradle-plugin:3.1.3 declares a component for use during runtime, and its dependencies declared externally:

- Incompatible because this component declares documentation and the consumer needed a library

- Other compatible attributes:

- Doesn’t say anything about its target Java version (required compatibility with Java 8)

- Doesn’t say anything about its elements (required them packaged as a jar)

- Doesn’t say anything about org.gradle.plugin.api-version (required ‘8.2.1’)

- Variant ‘mavenOptionalApiElements’ capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.1.3 declares a library, packaged as a jar, and its dependencies declared externally:

- Other compatible attribute:

- Doesn’t say anything about org.gradle.plugin.api-version (required ‘8.2.1’)

- Variant ‘mavenOptionalRuntimeElements’ capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.1.3 declares a library for use during runtime, packaged as a jar, and its dependencies declared externally:

摘要

本文将讨论如何解决 Spring Boot Gradle 插件和 Java 版本之间的兼容性问题。特别是当 Spring Boot Gradle 插件要求的 Java 版本与项目当前使用的 Java 版本不匹配时，如何解决这个问题。

引言

在 Java 项目开发中，经常会遇到库或插件与当前 Java 版本不兼容的问题。Spring Boot 和 Gradle 是两个常用的 Java 开发工具，但它们也不例外。本文将详细介绍如何解决这个问题，特别是如何调整 IntelliJ IDEA 项目环境。

解决问题的步骤和方法

1. 识别问题

首先，我们需要确定问题的来源。通常，当执行 Gradle 构建任务时，控制台会显示错误消息。这些消息通常会提供足够的信息来确定问题。

2. Java 版本

升级 Java 版本

• 在 IntelliJ IDEA 中，转到 File -> Project Structure -> Project
• 在 Project SDK 部分，选择一个 Java 17 的版本
• 点击 Apply 和 OK

在 build.gradle 中指定 Java 版本

sourceCompatibility = 1.17
targetCompatibility = 1.17

3. Spring Boot Gradle 插件版本

在 build.gradle 文件中，找到 Spring Boot Gradle 插件的版本，并更改为与新的 Java 版本兼容的版本。

plugins {
    id 'org.springframework.boot' version '3.1.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
}

4. Gradle 版本

确保 Gradle 版本与您使用的 Spring Boot 版本兼容。在 gradle-wrapper.properties 文件中，更新 Gradle 的版本。

5. 设置 Gradle JVM

• 在 IntelliJ IDEA 中，转到 File -> Settings (或 Preferences) -> Build, Execution, Deployment -> Build Tools -> Gradle
• 在 Gradle JVM 部分，选择或安装一个 Java 17 的版本。
• 点击 Apply 和 OK

调整 IntelliJ IDEA 项目环境为 Java 17

• 打开 IntelliJ IDEA
• 转到 File -> Project Structure -> Project
• 在 Project SDK 部分，选择或安装一个 Java 17 的版本
• 点击 Apply 和 OK

现在，您的 IntelliJ IDEA 项目应该已经配置为使用 Java 17。

结论

解决 Spring Boot 和 Gradle 的 Java 版本兼容性问题并不复杂，但需要注意细节。只需几个简单的步骤，您就可以使您的项目与所需的库和插件版本兼容。

总结

Java 版本兼容性是 Java 开发中常见的问题之一。通过本文，您应该了解了如何识别问题，以及如何一步步地解决问题，包括如何在 IntelliJ IDEA 中设置 Java 17 环境。
