playVer is 2.6.14.... So need to pull in newer Guice version that works with Java 17... It's only in test scope however. But I think this needs more refactoring...

Instead of -target we should use -release, which however is not availabe in Scala 2.11. Bad news is in Scala 2.11 we can not set -target to Java 11:

$ scalac -version
Scala compiler version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL

$ scalac -help
...
-target:<target>   Target platform for object files. All JVM 1.5 targets are deprecated. (jvm-1.5,jvm-1.6,jvm-1.7,jvm-1.8) default:jvm-1.6

So... if we drop Java 8 for anorm... we might also should think about dropping Scala 2.11? The last release was cut 5 years ago...

To be honest I would even drop Scala 2.12... build.sbt does lot of conditional stuff to make everyhing work. I think it's time to move on for people. Scala 2.13 has been out for a long time already and it just gets harder and harder to support older Scala and Java releases...

BTW: I do not se a reason to not set release for Scala 3, should be totally fine.
