When you are developing and testing a plug-in, you can trigger redeployment frequently by using the Redeploy button, without the need to make changes to the extension registration record. After the Redeploy button is enabled, it is visible in the Client Plug-Ins window, where it applies to any selected plug-in. The button causes vCenter Server to undeploy the selected plug-in, and then deploy it again based on the same registration record.

Screenshot shows the location of the Redeploy feature.

To enable the Redeploy button, set pluginDeveloperMode by appending the query parameter pluginDeveloperMode=true to any URL loaded into the browser window. For example, the URL could be the following:

https://vcenter-server-fqdn/ui/?pluginDeveloperMode=true

When you set pluginDeveloperMode, it remains in effect until you browse to a URL that contains the query parameter pluginDeveloperMode=false, or until you refresh the browser window while the browser addres field does not include pluginDeveloperMode=true.
