[solved] The import org.bubblecloud.zigbee.network.port cannot be resolved

For import org.bubblecloud.zigbee.network.port.ZigBeePort; in zigbee binding, I can NOT find ZigBeePort.java in zigbee4java to import some external library.

How should I resolve eclipse error “The import org.bubblecloud.zigbee.network.port cannot be resolved”?

The zigbee binding I clone by,
$git clone https://github.com/cdjackson/openhab2-addons.git --branch zigbee --single-branch

Thank you.

simply Eclipse -> Import project, choose zigbee binding under openhab2-addons. All good.
