I am trying to use some of latest version kotlin library with rush but we are facing this build error :

module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.7.1, expected version is 1.5.1.

Have any way to resolve this issue ?

Rush currently only supports v1.5.32 of Kotlin. However, you can manually upgrade it. Here's how:

Download latest kotlin-compiler.zip from here.
Go to $RUSH_DATA_DIR/tools/kotlinc and replace it's contents with the ones from the above ZIP. On Windows, $RUSH_DATA_DIR is %AppData%\rush; on Linux, it's $HOME/rush.
Then, go to $RUSH_DATA_DIR/tools/kotlinc/lib, and then copy annotations-13.0.jar, kotlin-stdlib.jar and kotlib-stdlib-sources.jar from there to $RUSH_DATA_DIR/dev-deps/kotlin.
Done!
