## Development Information

### Get Source Code

1. Clone Fess's repository:
    ```
    $ cd ~/workspace
    $ git clone https://github.com/codelibs/fess.git
    ```
    
2. Import the cloned repository as a [Maven](https://maven.apache.org/) project on [Eclipse](https://www.eclipse.org/eclipseide/) or another IDE.

### Setup for OpenSearch Plugins

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

        if (first != null) {

            Subject cachedOrig = orig.getSubject();
            assertNotNull(cachedOrig);

            // Cached subject is copied and visible via getSubject()
            Subject copySubj = copy.getSubject();
