Jörn Kottmann commented on OPENNLP-161:
---------------------------------------
There are exactly 6 mandatory arguments and that is why I believe the test
should be args.length != 6.
> SentenceDetectorEvaluator has incorrect validation for number of command line
> arguments

> Key: OPENNLP-161
> URL: https://issues.apache.org/jira/browse/OPENNLP-161
> Project: OpenNLP
> Issue Type: Bug
> Components: Sentence Detector
> Affects Versions: tools-1.5.1-incubating
> Reporter: Stanislav Peshterliev
> Priority: Minor
> Fix For: tools-1.5.1-incubating
>
>
> When I execute
> {code}
> opennlp SentenceDetectorEvaluator -encoding UTF-8 -model pt.sentdetect.model
> -data pt.sentdetect.test
> {code}
> the result is
> {code}
> Usage: opennlp SentenceDetectorEvaluator -encoding charset -model model -data
> testData
> {code}
> I got the usage message although the right number of arguments. After short
> investigation I have found out that in the class
> SentenceDetectorEvaluatorTool, the validation for number of arguments is
> incorrect.
> {code}
> if (args.length != 4) {
> System.out.println(getHelp());
> throw new TerminateToolException(1);
> }
> {code}
> Actually args.length is 6. Changing the condition to args.length < 6 solves
> the problem.
