Spring 引导应用程序构建失败

Question

我正在尝试在本地构建此存储库https://github.com/spring-projects/spring-petclinic我按照存储库中的步骤进行操作，但构建结果如下所示：

[INFO] BUILD FAILURE

[INFO] ------------------------------------------------------------------------

[INFO] Total time: 6.757 s

[INFO] Finished at: 2023-01-23T15:27:08+02:00

[INFO] ------------------------------------------------------------------------

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:3.0.1:build-info (default) on project spring-petclinic: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:3.0.1:build-info failed: Unable to load the mojo 'build-info' in the plugin 'org.springframework.boot:spring-boot-maven-plugin:3.0.1' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: org/springframework/boot/maven/BuildInfoMojo has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0.

我的 Java 版本是：

$ java -version

openjdk version "11.0.17" 2022-10-18

OpenJDK Runtime Environment (build 11.0.17+8-post-Ubuntu-1ubuntu218.04)

OpenJDK 64-Bit Server VM (build 11.0.17+8-post-Ubuntu-1ubuntu218.04, mixed mode)

而 Maven 版本是：

$ mvn -v

Apache Maven 3.6.0

Maven home: /usr/share/maven

Java version: 11.0.17, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64

Default locale: en, platform encoding: UTF-8

OS name: "linux", version: "5.10.102.1-microsoft-standard-wsl2", arch: "amd64", family: "unix"

我试图从回购协议中运行这些步骤，但这对我没有用。

Answer 1

class 文件版本 61.0 = Java 17. 如果您尝试通过 IDE 运行项目，它将使用独立于为终端类路径配置的版本 java。 本教程提到了 Intellij，所以我假设这就是您正在使用的。 Go 进入File -> Project Structure ，您将在该项目中拥有 SDK 和语言级别，确保它们是正确的版本。

Answer 2

尝试 Java 14 或以上来处理：

Java SE 14（或JDK 14）是处理版本号为61.0的class个文件的版本
