2. Install
[JDK7](http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html) and set
`JAVA_HOME` in the system environment variables.

3. Download and install [Maven](http://maven.apache.org/download.html). Also include the `bin`
directory in Maven in `PATH`.

4. Set `MAVEN_OPTS` as described in [Building Spark](http://spark.apache.org/docs/latest/building-spark.html).
5. Open a command shell (`cmd`) in the Spark directory and run `mvn -DskipTests -Psparkr package`

5. Open a command shell (`cmd`) in the Spark directory and build Spark with [Maven](http://spark.apache.org/docs/latest/building-spark.html#building-with-buildmvn) and include the `-Psparkr` profile to build the R package. For example to use the default Hadoop versions you can run

```bash
mvn.cmd -DskipTests -Psparkr package
```

`.\build\mvn` is a shell script so `mvn.cmd` should be used directly on Windows.
