### Setup for OpenSearch Plugins

Run antrun:run to download plugins into the plugins directory:

    $ mvn antrun:run

### Run Fess

Run or debug org.codelibs.fess.FessBoot on your IDE, and then access http://localhost:8080/

### Build Package

Run the `package` goal and then the release file will be created in target/releases.

    $ mvn package
