run Sample data erroe

hello,
I hope to participate in the WMT19 QE task
when I run 
```shell
cd sample-data/ java -jar ../tercom.jar -r ref.txt -h hyp.txt > out.txt
```

>  Error: unable to find or load the main class ter.tertest
then I change build.xml 28line
```xml
<attribute name="Main-Class" value="ter.TERtest" />
```
to
```xml
<attribute name="Main-Class" value="ter.TER" />
```

it's OK
