This step is to be performed after every upgrade of the Studio plugin. It updates the latest Pricefx API JavaDoc documentation and API auto-completion in your currently open projects:
Open the project in IntelliJ IDEA.
Open the Maven tool window and click theĀ Reload button.
This will add Studio: net.pricefx:groovy-api library in External libraries.
Consider cleaning cache if you still do not get the latest API. For details see Troubleshooting Pricefx Studio.
