# Building Applications with Freestyle Jobs

> Markdown source of <https://docs.calebsargeant.com/computing/jenkins/getting-started/building-applications-with-freestyle-jobs/>.

## Anatomy of the Build

- Git repo
  - Compile
  - Test
  - Package
  - Clean
  - rinse & repeat

## Manually Building with Maven and Running App

``` bash
git clone git@github.com:CalebSargeant/jgsu-spring-petclinic.git --config core.sshCommand="ssh -i ~/.ssh/github"
cd jgsu-spring-petclinic
./mvnw compile
./mvnw test
./mvnw package
java -jar target/spring-petclinic-2.3.1.BUILD-SNAPSHOT.jar
```

## Packaging an App in Jenkins

!!! note


    Workspaces are temporary!
