SAPUI5 version in a Web App

The UI5 version can be changed either by manually adding the version field to the neo-app.json file, or by right-clicking on the project and choosing Project > Project Settings.
 




 

Clink on "Save" after select the SAPUI5 version.

See the changes in  neo-app.json file:



It is recommended to set a specific UI5 version for your app before making it available to your users. This ensures that your app runs in the environment you tested it in during your development phase. Make sure that you always refer to a specific SAPUI5 version instead of using the generic reference to the latest released version. Use the generic reference for testing purposes only.
