Maven Integration

Apache OpenNLP is also distributed via Maven Central Repository. The Apache OpenNLP project publishes the library, javadoc and source code jars. To use OpenNLP in your Maven project, specify exactly one of the following dependencies, all transient dependencies are resolved automatically.

Apache OpenNLP 3.x Series

To use OpenNLP as a library define the following dependency:

Runtime dependency

<dependency>
    <groupId>org.apache.opennlp</groupId>
    <artifactId>opennlp-runtime</artifactId>
    <version>3.0.0-M2</version>
</dependency>
Note
 Only opennlp-runtime needs to be added as a dependency, and you can add additional modules (e.g. opennlp-ml-maxent, opennlp-dl, etc.) as required.

Model Resolver dependency

If model classpath scanning support is required, just add:

<dependency>
    <groupId>org.apache.opennlp</groupId>
    <artifactId>opennlp-model-resolver</artifactId>
    <version>3.0.0-M2</version>
</dependency>
Tip
 Other components can be declared similarily as in the previous 2.x release, see below. Check the Developer Manual for a detailed outline of existing components.
