error Matlab function for accessing the Stanford POS tagger

I used bellow function in MATLAB for Stanford POS tagging :

function result = PosTaggerM(str)
% The imports are probably a one time requirement, and add no overhead.
import java.io.*;
import edu.stanford.nlp.tagger.maxent.MaxentTagger;
tagger = MaxentTagger('./english-left3words-distsim.tagger');
result = java.util.ArrayList();
sentences = MaxentTagger.tokenizeText(StringReader(str));
for ii = 1:size(sentences)
    tSentence = tagger.tagSentence(sentences.get(ii-1));
    result.addAll(tSentence);
end
end

But I received this error:

"Arguments to IMPORT must either end with ".*" or else specify a fully qualified class name:"edu.stanford.nlp.tagger.maxent.MaxentTagger" fails this test."

I'll be very grateful if someone gives me some helpful suggestions and advice to eliminate the error? Thanks

I found a download for the software at https://stanfordnlp.github.io/CoreNLP/

... but OS-X javac complains about a lot of problems in the code.

... and the apache tools to rebuild it don't work for me...

Sigh.

Which MATLAB release are you using? There were some difficulties with import in some of the older versions.
