# ${docGenStepName}

## ${docGenDescription}

## Prerequisites

While using a custom docker file, ensure that the following tools are installed:

* **SAP MTA Archive Builder 1.0.6 or compatible version** - can be downloaded from [SAP Development Tools](https://tools.hana.ondemand.com/#cloud).
* **Java 8 or compatible version** - necessary to run the *MTA Archive Builder* itself and to build Java modules.
* **NodeJS installed** - the MTA Builder uses `npm` to download node module dependencies such as `grunt`.

## ${docGenParameters}

## ${docGenConfiguration}

## Side effects

1. The file name of the resulting archive is written to the `commonPipelineEnvironment` with variable name `mtarFileName`.

## Exceptions

* `AbortException`:
  * If there is an invalid `buildTarget`.
  * If there is no key `ID` inside the `mta.yaml` file.

## Example

```groovy
def mtarFileName
dir('/path/to/FioriApp'){
  mtarFileName = mtaBuild script:this, buildTarget: 'NEO'
}
```
