In Premiere Pro 25.6 Beta, my UXP plug-in does not load.

[broadcastingengineer]

I’m trying to run a plug-in built with the UXP framework in Premiere Pro 25.6 Beta.

When I load the plug-in using the UXP Developer Tool, it runs correctly in Premiere.

However, when I place the plug-in folder directly into
~/Library/Application Support/Adobe/UXP/Extensions/
and try to launch it via Window > UXP Extensions in Premiere, the plug-in doesn’t appear.
In the UXP Extensions menu, I only see options like “Browse Plug-ins” and “Manage Plug-ins,” but not the plug-in I placed manually.

How can I make the plug-in appear in the UXP Extensions menu without using the UXP Developer Tool?

Also, I’m wondering: now that UXP Extensions are available, are classic extensions (CEP) no longer supported?

Hi broadcastingengineer, 

I'll start at the end; CEP extensions are 100% definitely still supported. The plan is to continue to support them for a calendar year beyond the release of UXP extensibility (in non-beta PPro builds). 

As for getting UXP plugins to load without involving UXP Developer Tools (UDT)...

Your built plugin directory should be placed within:

~/Library/Application Support/Adobe/UXP/Plugins/External

But wait! There are further requirements. 🙂

The name of your plugin's containing folder must consist of:

1. The id declared in the plugin's manifest.json,
2. followed by an underscore _ , then
3. The three digit version number, also from the plugin's manifest.json.

For the unmodified 3psample example, that means that the plugin's directory shall be named:

com.adobe.ppro.samples_1.0.0

 
Following [above], I'm able to load the 3psample in today's PPro beta build, without UDT.
