# Building an App

Apps are built for the first time when they are created, based on the default code for the App type chosen in the [**Create App** window](/v1/docs/administrative-functions-for-projects-and-apps), and then incrementally as you type. However, there are some cases where a manual build is required to fully build the project—for example, if a dependency is added or parameters have been modified. An App must be built before it can be debugged, tested, and released.

To build an App, click **Build Project**![A white square with a black letter on it Description automatically generated with low confidence](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Build%20icon_App%20Builder.png)to the left of the **Built** section of the [**Summary** tab](/v1/docs/summary-tab) (Figure 1).

If the build is unsuccessful, a **failure**![](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Failed%20Build%20icon_App%20Builder.png)icon will be displayed in place of the **Build Project**![A white square with a black letter on it Description automatically generated with low confidence](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Build%20icon_App%20Builder.png)icon, and the timestamp will be updated. The project will need to be modified and built successfully in order to proceed with debugging, testing, and release.

If the build is successful, a **success**![](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Successful%20Build%20icon_App%20Builder.png)icon will be displayed in place of the **Build Project**![A white square with a black letter on it Description automatically generated with low confidence](https://cdn.document360.io/dfc206c8-1c9f-4725-b74d-a66f83432320/Images/Documentation/Build%20icon_App%20Builder.png)icon, and the timestamp will be updated.

## Build Log Tab

The log of the most recent build will be available in the **Build Log** tab (Figure 2).

In addition to the build log, this tab displays the **Status** of the build (**Successful** or **Unsuccessful**) and any **Status Message** that is available. If a build is unsuccessful, a **Rebuild** button will be displayed in the tab.
