I m trying to import the kotlinx datetime library into a jup

Question

I m trying to import the kotlinx datetime library into a jupyter notebook I thought I understand the syntax but apparently not ``` file DependsOn org jetbrains kotlinx kotlinx datetime 0 3 2 useLatestDescriptors use lets plot import java util Random import kotlinx datetime Instant``` Running that yields the error `Line 214 jupyter kts 6 25 32 Unresolved reference Instant` What am I missing

Use kotlinx datetime jvm Maven resolver in the notebook can t us gradle metadata to automatically add suffixes for MPP libraries

Carter · Answer

I did try that also but it didn t work for me either Specifically ``` file DependsOn org jetbrains kotlinx kotlinx datetime jvm 0 3 2 ```

Carter · Answer

I ve also tried creating a json descriptor and loading that ``` description Datetime properties v 0 3 2 link <https github com Kotlin kotlinx datetime> dependencies org jetbrains kotlinx kotlinx datetime jvm $v imports kotlinx datetime Instant ``` Then ``` use file data notebook files datetime json ``` Which gives effectively the same error ```The problem is found in one of the loaded libraries check library imports dependencies and repositories Error compiling code file DependsOn org jetbrains kotlinx kotlinx datetime jvm 0 3 2 import kotlinx datetime Instant Errors Line 247 jupyter kts 2 25 32 Unresolved reference Instant```

You can t use import in the same cell as dependency loading I am not sure it is covered somwhere in the documentation The problem is that cell with dependency loading uses old class loader

Carter · Answer

I don t think I ve ever seen that documented

altavir · Answer

< Ilya Muradyan> Probably it should be covered somewhere

Carter · Answer

I also think there was a problem with the Jupyter Kernel I m also using datalore and when I copied and pasted your example t to the top of my notebook it didn t work until I restarted the kernel

altavir · Answer

Yes classpath needs to be reset if it is broken and the only way is to restart kernel

Carter · Answer

So there might be a confluence of three issues 1 Need to document putting ` file` in its own cell before import 2 Need to document using ` jvm` suffix for multiplatform libraries 3 Possibly some bug in the kernel that didn t get cleared by re running the cell I ll have to see if I can reproduce it

Carter · Answer

But the good news is that I m unblocked so thank you for the response and the help

Ilya Muradyan · Answer

Re running the cell shouldn t clear the state It s by design I ll document 1 and 2 thank you

Carter · Answer

I hit 2 then added jvm and then re ran the cell that configured my import and it still failed This didn t meet my expectations as a user which then lead me to come to this Slack for help with the issue I m not sure what the right solution is but this does make error recovery difficult
