### Build Package

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

    $ mvn package
    $ mvn rpm:rpm   # .rpm package
    $ mvn jdeb:jdeb # .deb package

### Generate Source Code

    $ mvn dbflute:download # (one time command)
    $ mvn dbflute:freegen
    $ mvn license:format

### Integration Tests

Launch Fess Server and run the following command:

            logger.debug("Create thumbnail task: {}", task);
        }
        return task;
    }

    @Override
    public boolean generate(final String thumbnailId, final File outputFile) {
        if (logger.isDebugEnabled()) {
            logger.debug("Generate Thumbnail: {}", thumbnailId);
