Mule dev-kit and custom connector

Question

I am experimenting with Mule Custom connectors these days. I followed all the steps described at Barn Connector to see a sample working connector. It doesn't download core mule api and its related libraries and modules, so compilation errors are occurred. Can any provide me the solution?

EDIT: Mule devkit annotations are not resolved:

import org.mule.api.annotations.ConnectionStrategy;
import org.mule.api.annotations.Connector;
import org.mule.api.annotations.Configurable;
import org.mule.api.annotations.Processor;
import org.mule.api.annotations.param.Default;

The above imports are not resolved.

Answer 1

If the build is successful it should be a problem with your IDE, try invalidating the Cache and restart. I Also recommend you to download the DevKit plugin from help -> install new software in studio.

Cheers
