I'm developing a simple REST service to return HARDCODE data and I'm stuck trying to build the jar of the project. After I check the REST worked well I tried to create the JAR but I couldn't.
Currently this is my pom.xml file.

Currently this is the error when I executed mvn clean package
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.12.1:compile (default-compile) on project technical_test: Fatal error compiling: error: release version 17 not supported.
Initially the project was with JAVA 21 but I got the same error
Ok, is not supported. How can I found a supported versión (in maven documentation is not clear for my) or how can I fix this error?
I'm new in this, so I'll be please with your help
I strongly recommend to use it like this:

I have used java.version
in that setup but that's no even required because it's defined in the parent.
I also strongly recommend to remove hibernate-jpa-2.1-api in that version because Spring Boot already offers an appropriate version... which is at version: 6.4.1.Final... Check also the documentation... also the groupId has changed for Hibernate...
<dependency>
<groupId>org.hibernate.orm</groupId>
...
</dependency>
This is also valid for servlet-api ... that has been changed in the namespace... (groupId) based on Jakarta EE Change
Update
The output for mvn --version
should like this:
