IDEA how to write java class (UDF function) labeled jar package upload linux

I wrote UDF function

 1 import org.apache.hadoop.hive.ql.exec.UDF;
 2 import org.apache.hadoop.io.Text;
 3 
 4 public final class Lower extends UDF {
 5     public Text evaluate(final Text s){
 6         if (s == null){
 7             return null;
 8         }
 9 
10         return new Text(s.toString().toLowerCase());
11     }
12 }

Directly at the command line: mvn clean package

Lay the jar package
