Can't build addons

Hello,

i downloaded the https://github.com/openhab/openhab1-addons repo
when i try to build one of the binding (serial) using “mvn clean package” i get following error:

ERROR in C:\Projects\OpenHab\openhab-master\git\openhab1-addons\bundles\binding\org.openhab.binding.serial\src\main\java\org\openhab\binding\serial\internal\SerialDevice.java (at line 257)
[ERROR] serialPort = portId.open(“openHAB”, 2000);

Can anyone help me with this?
