There are 2 ways to try Fess. The first is to download and install yourself. The second is to use [Docker](https://www.docker.com/products/docker-engine).

### Download and Install/Run

Fess 15.5 is now available and can be downloaded on the [Releases page](https://github.com/codelibs/fess/releases "download"). Downloads come in 3 flavors: deb, rpm, zip.

The following commands show how to use the zip download:

    $ unzip fess-15.5.x.zip

        return asIndexHtml();
    }

    /**
     * Downloads a log file by its encoded ID.
     *
     * @param id the Base64 encoded filename of the log file to download
     * @return ActionResponse containing the log file stream
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public ActionResponse download(final String id) {

As indicated, each of those components require a Java runtime to run.

The recommended way of invoking Gradle is to use the Gradle Wrapper.
The Wrapper then downloads the Gradle distribution (if necessary), starts the Launcher and runs the build, spawning and connecting to other processes such as the Daemon as required.

        return asDownloadHtml();
    }

    /**
     * Downloads elevate words data as a CSV file.
     *
     * @param form download form with export options
     * @return streaming response containing CSV data
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public ActionResponse download(final DownloadForm form) {
        verifyToken(this::asDownloadHtml);
