I am trying to build locally this repository https://github.com/spring-projects/spring-petclinic I followed the steps from the repo but the build result looks like this:
[INFO] BUILD FAILURE

[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.
My Java version is:
$ 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)
And Maven version is:
$ 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"
I tried to run the steps from the repo, but that didn't worked for me.
Try Java 14 or above to handle this:
Java SE 14 (or JDK 14) is the version that handles class files with a version number of 61.0
