# Build

A build task creates a deployment package for your app. The following options are available:

* **Proceed on Failure.** If enabled, the pipeline will continue executing when this step fails.
* **Which branch do you want to use?** Specify the source branch for this pipeline. The choices are:
  * **Mainline :** When selected, the pipeline will automatically use the mainline of the app for the build.
  * **Specific branch :** When selected the user of the pipeline must select a specific branch to be used.
  * **Branch name** : When selected, provide the name of the branch to use. When the pipeline executes the system will try to find a branch with the name you provide.
* **Which revision do you want to use?** Specify the source revision for this pipeline. The choices are:
  * **Latest :** When selected, the pipeline will automatically use the latest revision of the source branch configured for the pipeline.
  * **Specific revision :** When this is selected the user of the pipeline must select a specific revision to be used each time the pipeline is run.

{% hint style="info" %}
If you select a branch or revision in this task, these cannot be changed by the user of the pipeline when creating a new release. If you want the user to be able to select a specific branch or revision you must select 'specific branch' or 'specific revision'.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bluestorm.io/administration/pipelines/build.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
