Validate the manifest.webpackage file

As you may know, the manifest.webpackage file must follow a JSON schema according to its model version. The CDT offers you the +webpackage-validateManifestFile task to validate the manifest of your current webpackage automatically.

Note that the manifest is validated before being uploaded, and if it is not valid the upload will be interrupted.

Purpose

To show how to validate the manifest of a webpackage using the +webpackage-validateManifestFile` task.

Steps

You should run the task within the CDT folder (normally it is called devtools) as follows:

grunt +webpackage-validateManifestFile

Outcome

If the manifest has errors, those will be prompted. Otherwise, you will get a message similar to the one below:

Done, without errors.
