This is a known bug, where the build caches don’t invalidate after you remove dependencies. For now, deleting the build folder for your extension, which can be found inside $RUSH_DATA_DIR/workspaces, should fix this.
I think you should add clean command similar to Extension Template.

I have installed JDK 1.8 and added the %JAVA_HOME% variable correctly?
then why this error occurs?
How to fix this??
Try running javac -version and see the results.
For me, it returns:
javac 1.8.0_331
On my laptop, the two commands worked but javac did not, and I encountered the same error as you. Then I changed some things and javac was working, and the extensions are now compiling.
So what do I need to change? because my laptop doesn’t display the javac -version you described above… I need your help.
What does it say?

How I can update or specify the Kotlin version in Rush for creating extension in Kotlin?
The error message you are getting is telling you that the Kotlin classes that you are trying to use are compiled with an incompatible version of Kotlin. This means that the versions of Kotlin that the classes were compiled with and the version of Kotlin that you are using to run your code are different.

weren’t there plans to integrate python the? Could this be done with Jython, for example?
Jython link
There were no plans whatsoever to integrate Python or Jython into Rush.

When building extensions with Kotlin, it is necessary to generate a release build otherwise the extension won’t work in Kodular. To generate a release build, pass the -r (--release) flag when building the extension:
rush build -r

option ‘-dontwarn’ in Rush - not supported?
You need to add them in the progaurd configuration file, to ignore all the errors you can just:
-dontwarn
