Katalon import errors

I’m trying to create my own plugin, but I face the following issue:

import com.kms.katalon.core.checkpoint.CheckpointFactory
^

Applies for all the katalon.core imports…

What is wrong here?

Hi @dekleijn.roy,

Please open your plugin project by Katalon Studio once time then build again.

Thanks.

Ok the imports seems to work in katalon studio… but how can you build the plugin there ?

I tried building it in Intellij but still no luck…
