<![CDATA[Error Importing Modbus4J Library in Netbeans]]>Hi.
I am trying this library, I have funded the test code in the src/Test
I have added the code to fresh NetBeans project and import the Modbus4J library from the right side library import panel.
but still its showing error in the code.
I tried with alt+enter but it's not showing to import option.

package modbustestlibrery;
/**
 *
 * @author mdism
 */
public class myModbus {

    /**
     * @param args the command line arguments
     */
        public static void main(String[] args) throws Exception {
            
     ModbusFactory factory = new ModbusFactory();
     IpParameters params = new IpParameters();
     params.setHost("localhost");
     params.setPort(12345);
     ModbusMaster master = factory.createTcpMaster(params, true, false);
     // master.setRetries(4);
     master.setRetries(0);
     try {
     master.init();
     master.getValue(1, RegisterRange.HOLDING_REGISTER, 0, DataType.TWO_BYTE_INT_UNSIGNED);
     }
     finally {
     master.destroy();
     }
     }
    
}


This is the error i am getting

Is modbus4j on your classpath?
