SharePoint 2013:a feature with ID have already been installed in this farm

Using Visual Studio 2013 to create a Visual Web Part, when you right-click the project, select the "Deploy" Times error:

"Error occurred in Deployment Step ' ADD Solution ': A feature with ID 15/3e472a61-bbc9-4242-87c7-a07e8e3fab99 have already b Een installed in this farm. Use the force attribute to explicitly re-install the feature. "

Cause of Error:

After a site deployment is complete, this error is reported if you modify the site URL in the project properties to deploy to another site.

Workaround:

In fact, the error message has been mentioned: "Use of the Force attribute to explicitly re-install the feature."

Add the "Force" property?

1. Double-click Feature

2. On the "Manifest" tab, now "Open in XML editor"

3. In the feature node, add the property "Alwaysforceinstall" and save it when finished.

4. Re-deploy, success!
