spring-boot - IntelliJ Gradle 构建失败 : Incompatible because component compatible with Java 17 and the consumer needed Java 11

Question

在 IntelliJ 中，当我对从 start.spring.io 下载的新项目进行干净构建时，出现错误。

Spring Configuration on start.spring.io

我已经安装了直接从 IntelliJ 下载的 Java 17 JDK (Amazon Corretto)

在终端中，运行命令:./gradlew clean build

导致以下错误:

BUILD FAILED in 1s

在此先感谢您的帮助

尝试过:

1. 确保项目在 File -> Project Structure 下使用 Java 17 SDK
2. 确保 Gradle JVM 指向 IntelliJ IDEA -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle 下的 Java 17 SDK
3. 试图改变 build.gradle 文件

sourceCompatibility = (11 or 17)
targetCompatibility = (11 or 17)

java {
  toolchain {
    languageVersion = JavaLanguageVersion.of( (11 or 17) )
  }
} 

奇怪的是，如果我只点击 IntelliJ 上的“播放”按钮，项目就可以正常构建

Spring Boot 3 要求最低版本 JDK 17。

如果你想使用 JDK 17 或更高版本配置带有 gradle 的 InteliJ，则需要以下配置。

1. File -> Project Structure -> Project -> Project SDK -> 指定jdk 17以上

1. 您还需要以下配置。 文件 -> 设置 -> 构建、执行、部署 -> 构建工具 -> Gradle -> Gradle JVM 并指定 jdk 为 17 或更高版本。

请记住，上述配置适用于 gradle 的嵌入式版本，InteliJ 将其用作嵌入式工具。 不是配置为从终端运行的那个

为了使用gradle终端的嵌入式工具版本，根据上述配置已经设置了Jdk 17，您需要运行如下所示的命令波纹管:

这应该足以执行您的项目。

否则 如果您坚持使用终端执行gradle命令，那么您需要在环境变量中进行所有必要的适配。为此，请进入 File -> Settings -> Tools -> Terminal -> Enviroment Variables 。要使环境更改生效，您必须重新启动 InteliJ 窗口。重新启动后，您可以使用 gradle -version 命令确认是否设置了正确的 JVM 和 gradle 版本。您也可以使用 java -version 查看终端指向的 JDK。 Spring Boot Initializer 还提供了一个可移植的 gradle 文件，该文件兼容运行项目。因此，如果您在环境属性下在您的系统中安装了另一个 gradle，您可以使用上述命令检测并删除，以便您只能使用已发货的本地版本。
