# exposed

hello 👋 not sure if this is the right channel.
I have a strange behaviour exposed with ktor. Intellij IDE, while running the Ktor application do not add the org.jetbrains.kotlinx/kotlinx-datetime , to the classpath, which ends with (obviously) java.lang.ClassNotFoundException: kotlinx.datetime.TimeZone
I am not even using kotlinx-datetime, I switch to javatime. Nevertheless, any table that is using timestamp field, fails add it to database in runtime.

Works great when I run application from terminal, it's only Intellij that omit that dependency while generating the runtime classpath for app.
The workaround is to open the run option, select more options (altr+m) add 'modify classpath', and select jar manually, ex ~/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlinx/kotlinx-datetime-jvm/0.8.0-0.6.x-compat/c4bf6532a54e118f35afb24ac5f0dacacfc90e63/kotlinx-datetime-jvm-0.8.0-0.6.x-compat.jar

it doesn't matter which kotlinx-datetime I use:

0.8.0-0.6.x-compat 
0.7.1-0.6.x-compat
0.8.0

none is recognised.
