What is wrong with my pom file causing this build error?-CodePudding

I have reinstall Java and reset JAVA_HOME to make sure maven is using the correct java version but am continuing to receive this error:

#9 67.23 [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:3.0.1:repackage (repackage) on project backend: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:3.0.1:repackage failed: Unable to load the mojo 'repackage' 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/RepackageMojo 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 60.0

I currently am getting these outputs:

What could be wrong with the following pom.xml file as I feel it is a dependency issue? Or could it be an issue with my Dockerfile?:

CodePudding user response：

Java 17 is the minimum requirement for spring boot 3.x version. Refer this link for more information. Set the Java environment to JDK17 to resolve the error.

You need Java 17 to run spring boot 3.
