### Build from Source
The other way to setup Druid is from source via git.
Builing Druid requires the following:
- [JDK 7](http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
or [JDK 8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
- [Maven version 3.x](http://maven.apache.org/download.cgi)
To do so, run these commands:
```
git clone git@github.com:druid-io/druid.git
cd druid
New extension loading mechanism 1) Remove maven client from downloading extensions at runtime. 2) Provide a way to load Druid extensions and hadoop dependencies through file system. 3) Refactor pull-deps so that it can download extensions into extension directories. 4) Add documents on how to use this new extension loading mechanism. 5) Change the way how Druid tarball is generated. Now all the extensions + hadoop-client 2.3.0 are packaged within the Druid tarball.

`distribution/target/druid-VERSION-bin.tar.gz`.
This will also create a tarball that contains `mysql-metadata-storage` extension under
`distribution/target/mysql-metdata-storage-bin.tar.gz`. If you want Druid to load `mysql-metadata-storage`, you can first untar `druid-VERSION-bin.tar.gz`, then go to ```druid-<version>/druid_extensions```, untar `mysql-metdata-storage-bin.tar.gz` there. Now just specifiy `mysql-metadata-storage` in `druid.extensions.loadList` so that Druid will pick it up. See [Including Extensions](../operations/including-extensions.html) for more infomation.
