Eclipse Plugin only working on my machine

Question

I wrote a Eclipse plugin for adding hungry-deletion, and it appears to work on my machine. However, I had a few friends try it, and it doesn't seem to load at all on their machines. The installation process is just to copy the resulting .jar to the plugins/ subdirectory of eclipse. I've tried re-installing eclipse on my machine and installing the plugin again, and that seems to work. Is there a signing process or something I have to go through for my plugin to work on different machines? If not, what could be the issue?

Answer 1

It seems the problem is the plugin was written in Eclipse 3.6 and not working in Eclipse 3.5 installations.

Answer 2

Have you tried starting eclipse w/ the -clean flag?

Answer 3

try to copy the plugin not to plugins directory but to dropins
