> Instead of using {{source}} and {{target}} the new parameter {{release}} (https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#release) should be used with Java 9+ as that also checks whether the used API is provided in the target Java release (https://docs.oracle.com/javase/9/tools/javac.htm#GUID-AEEC9F07-CB49-4E96-8BC7-BCC2C7F725C9__GUID-D343F6B4-3FDD-43A8-AD24-43DD70214471).
> To be able to support both compilation with Java < 9 and above a profile should be used which either configured {{source}} and {{target}} or {{release}}. 
> You have  to observe though that the parameter values are different though, as the former supports 1.6, 1.7 and 1.8 the latter only supports 6, 7 and 8.
