'8' is not a valid choice for '-target'

I am using plugin for compiling Spark jobs and after upgrade plugin from 4.5.6 to 4.6.0, I am getting fail with message: '8' is not a valid choice for '-target'

Settings I use and I found it has some impact:

When I run mvn clean package I got error:

[INFO] --- scala-maven-plugin:4.6.0:compile (scala-compile) @ spark-testing ---
[INFO] Using incremental compilation using Mixed compile order

[ERROR] '8' is not a valid choice for '-target'
[ERROR] bad option: '-target:8'

I did some testing and when I remove maven.compiler.source and maven.compiler.target, compiling is OK, but I am unsure for the result.

Is there some configuration way how to change the configuration having maven.compiler set to 8 in place?
