Description Lars Vogel CLA 2010-07-12 15:56:42 EDT 
Hi,

today I exported a plugin and placed them in a subfolder of dropins. I used the Windows XP platform. 

This plugin was not discovered after restart of Eclipse. Only after I placed them into dropins directly Eclipse found them.

I believe subfolder are supposed to be working with dropins and p2.

Best regards, Lars

What is the exact directly structure that was not working for you? There are a bunch of different supported layouts.

Comment 2 Lars Vogel CLA 2010-07-12 16:09:53 EDT 
I called my folder "website" and placed the plugins into this folder. 

Is this not supported?
Comment 3 DJ Houghton CLA 2010-07-13 16:35:54 EDT 
No, this is not supported. I am surprised that you don't get an error message in the log file. I get the stack trace below when I tried it on my machine. Please refer to the above link to the wiki page for the supported formats.
