scala-maven-plugin my scala plugin fails to compile the code into java 11

Question

I am trying to move my project to JDK11 and Hadoop3. but however hard I am trying , the compiler is compiling the .class file into Java8 .. ( major version 52).

What am I missing ?

Here is the shorter maven target run output for the scala plugin just to compile the scala files.
