My first openNLP "Hello World" program - easy question
I'm trying to learn the Eclipse IDE and openNLP at the same time and
have what must an easy question.
I downloaded the source distribution placed in on Eclispse's workspace
directory and ran "mvm clean install" and it looks like all went well
(see quote below)
Next I write what I think should be an easy demo that starts like this:
public static void main(String[] args) throws IOException {
POSModel model = new POSModelLoader().load(new File("en-pos-maxent.bin"));
POSTaggerME tagger = new POSTaggerME(model);
Of course both POSModelLoader and POSTaggerME can not be resolved so I
try adding this at the start of the file
import opennlp.tools.cmdline.postag.POSModelLoader;
import opennlp.tools.postag.POSModel;
import opennlp.tools.postag.POSSample;
import opennlp.tools.postag.POSTaggerME;
And now Eclipse tells me that opennlp.tools can not be resolved. How
do I tell Eclipse where to look? I figure Eclipse must have a search
path.
The openNLP distribution is at
~/Documents/workspace/apache-opennlp-1.5.3/ If I cd to that location
and do "ls" here is what I get:
Chris Albertson's iMac:apache-opennlp-1.5.3 chris$ ls
LICENSE docs opennlp-docs
NOTICE issuesFixed opennlp-maxent
README lib opennlp-tools
RELEASE_NOTES.html opennlp opennlp-uima
bin opennlp-distr
Here is the result I got that makes me think it all built OK:
[INFO] Reactor Summary:
[INFO] Apache OpenNLP Reactor ............................ SUCCESS [17.192s]

If it matters this is the machine/environment I'd running this on
mvn --version

Posted by Richard Eckart de Castilho <re...@apache.org>.
I suggest you use Maven in Eclipse.
Make sure you have m2e (the Maven integration for Eclipse) installed.
Remove the checked-out projects from OpenNLP from your workspace
(do not tick the "delete from disk"). Use Import -> Existing Maven Projects
and point it to the place where you checked out OpenNLP to. This should
reimport the projects, this time as proper Maven projects.
When you create your own hello-world project, also create it as a Maven
project and add the opennlp projects you required as dependencies in the
Maven POM editor.
With m2e, there should be no need to run Maven on the command line at all.
Recent version of Eclipse (e.g. 4.3.x) may already come with m2e preinstalled.
Cheers,
