eclipse 3.0 can't activate plug in on startup eclipse?

[him]

I am working about creating plug-in in eclipse. At first I create plug-in
project in eclipse 2.1.3, It works.
Beacuse eclipse open new release eclipse 3.0, I must move plug-in project from
eclipse 2.1.3 to eclipse 3.0.

I try create new plug-in project in eclipse 3.0 and copy plug-in project into
eclipse\plugins
and when I open new eclipse window, I found that plug-in which I created
doesn't activated.
(I select Window>Show View>Other but I don't find plug-in that I created)
But I try create plug-in project in eclipse 2.1.3, eclipse 3.0 RC1, It works,
It is actaved on startup.
(I select Window>Show View>Other and I find plug-in that I created)
How will I do?
Thanks,

Hi,

This question is off topic here, the forum is for discussing oXygen XML editor related problems. For Eclipse questions you should use the Eclipse support channels starting at http://www.eclipse.org/newsgroups/index.html .

Eclipse 3 has some caching problems so you should try to delete the configuration directory content and see if your plugin shows up. See a similar problem some users experienced with oXygen here: http://www.oxygenxml.com/forum/ftopic486.html

Best Regards,
