Task - Add Java 21+ Support

[michaeltchuang]

Task - New macbooks have Java 21 installed instead of Java 17 by default….app module needs to be upgraded to support this.

The error you get is this if it’s not fixed

Invalid value (21) passed to --jvm-target, must be one of [1.6, 1.8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18]

Temporary workaround...switch gradle to use Java 17 in Android Studio

Also you can to add to your gradle.properties,

org.gradle.java.home=/opt/homebrew/opt/openjdk@17

I had an investigation on this issue.

This issue seems related to detekt as library.
This issue that comes from the dependency seems that is already solved here:

1. Fails to run with Kotlin 1.9.20 and Java 21 detekt/detekt#6645
2. Support Jvm 22 detekt/detekt#7458
   As mentioned this will be solved with the next release of Detekt. Right now we are running the detekt = "1.23.7" that is already the latest as of today
