<commit_before>## 2.1 Setting up your development environment

### 2.1.1 Get the code and run a local build

GoCD requires the following software packages to build

- JDK 8 (OpenJDK or Oracle)
- Git (1.9+)
- NodeJS 6.x (https://nodejs.org/en/download/)
- yarn package manager (https://yarnpkg.com/en/docs/install)

Assuming the codebase is cloned into `~/projects/go`, you need to execute the
following commands to build GoCD

```bash
~/projects/go$ unset GEM_HOME GEM_PATH # if you're using rvm
~/projects/go$ ./gradlew clean agentGenericZip serverGenericZip
```
