-- `--max_file_size=[MAX_FILE_SIZE]`

-`TEMP_DIR` is used as the [temporary directory for the jetty application context](https://www.eclipse.org/jetty/documentation/9.3.x/ref-temporary-directories.html). This is the directory into which the `gitbucket.war` file is unpacked, the source files are compiled, etc. If given this parameter **must** match the path of an existing directory or the application will quit reporting an error; if not given the path used will be a `tmp` directory inside the gitbucket home.

 You can also deploy `gitbucket.war` to a servlet container which supports Servlet 3.0 (like Jetty, Tomcat, JBoss, etc)

-JRebel integration (optional)
-=============================
-
-[JRebel](https://zeroturnaround.com/software/jrebel/) is a JVM plugin that makes developing web apps much faster.
-JRebel is generally able to eliminate the need for the slow "app restart" per modification of codes. Alsp it's only used during development, and doesn't change your deployed app in any way.
-
-JRebel is not open source, but we can use it free for non-commercial use.
-
-----
-
-## 1. Get a JRebel license
-
-Sign up for a [myJRebel](https://my.jrebel.com/register). You will need to create an account.
-
-## 2. Download JRebel
-
-Download the most recent ["nosetup" JRebel zip](https://zeroturnaround.com/software/jrebel/download/prev-releases/).
-Next, unzip the downloaded file.
-
-## 3. Activate
-
-Follow `readme.txt` in the extracted directory to activate your downloaded JRebel.
-
-You don't need to integrate with your IDE, since we're using sbt to do the servlet deployment.
-
-## 4. Tell jvm where JRebel is
-
-Fortunately, the gitbucket project is already set up to use JRebel.
-You only need to tell jvm where to find the jrebel jar.
-
-To do so, edit your shell resource file (usually `~/.bash_profile` on Mac, and `~/.bashrc` on Linux) and set the environment variable `JREBEL`.
-For example, if you unzipped your JRebel download in your home directory, you would use:
-
-```bash
-export JREBEL=~/jrebel/legacy/jrebel.jar      # legacy agent
-export JREBEL=~/jrebel/lib/libjrebel64.dylib  # new agent
-```
-
-You can choose the legacy JRebel agent or the new one.
-See [the document](https://zeroturnaround.com/software/jrebel/jrebel7-agent-upgrade-cli/) for details.
-
-Now reload your shell:
-
-```
-$ source ~/.bash_profile # on Mac
-$ source ~/.bashrc       # on Linux
-```
-
-## 5. See it in action!
-
-Now you're ready to use JRebel with the gitbucket.
-When you run sbt as normal, you will see a long message from JRebel, indicating it has loaded.
-Here's an abbreviated version of what you will see:
-
-```
-$ ./sbt
-[info] Loading project definition from /git/gitbucket/project
-[info] Set current project to gitbucket (in build file:/git/gitbucket/)
->
-```
-
-You will start the servlet container slightly differently now that you're using sbt.
-
-```

-For example, you can change the title on `src/main/twirl/gitbucket/core/main.scala.html` like this:

-```html

-    <img src="@helpers.assets("/common/images/gitbucket.svg")" style="width: 24px; height: 24px; display: inline;"/>

-## 6. Limitations
-
-JRebel is nearly always able to eliminate the need to explicitly reload your container after a code change. However, if you change any of your routing patterns, there is nothing JRebel can do, you will have to restart by `jetty:quickstart`.
