I'm working on developing a feature plugin for eclipse, which consists
of 6 different plugins.
I'm using 2.1 final.
Currently, my feature works fine if I launch it in the Runtime
workbench. When I export my plugins, everything appears to be exporting
properly. I then put all these plugins in a separate copy of eclipse,
and fire it up. All of the plugins except for one work properly. When
I double click on a file, that is supposed to launch in a custom editor,
I get a ClassNotFound exception. And I don't have a clue why. Here is
the plugin.xml file for the offending plugin:
<?xml version="1.0" encoding="UTF-8"?>
<plugin
id="lexgrid-ui-model.editor"
name="%pluginName"
version="0.1.1"
provider-name="Lexgrid.org"
class="org.lexgrid.ui.LexgridSchema_v21EditorPlugin$Implementation ">
<runtime>
<library name="lexgrid-ui-model.editor.jar">
<export name="*"/>
</library>
</runtime>
<requires>
<import plugin="org.eclipse.emf.ecore.xmi" export="true"/>
<import plugin="org.eclipse.emf.edit.ui" export="true"/>
<import plugin="lexgrid-ui-model.edit" export="true"/>
</requires>
<extension
point="org.eclipse.ui.editors">
<editor
name="Lexgrid Browser"
icon="icons/full/obj16/LexgridPublishedFile.gif"
extensions="lgp"
contributorClass=" org.lexgrid.ui.lexgridschema_v21.presentation.Lexgridschema_ v21ActionBarContributor "
class=" org.lexgrid.ui.lexgridschema_v21.presentation.Lexgridschema_ v21Browser "
id="lexgridSchemaV21.presentation.LexgridSchemaV21BrowserID ">
</editor>
<editor
name="Lexgrid Editor"
icon="icons/full/obj16/LexgridModelFile.gif"
extensions="lgm"
contributorClass=" org.lexgrid.ui.lexgridschema_v21.presentation.Lexgridschema_ v21ActionBarContributor "
class=" org.lexgrid.ui.lexgridschema_v21.presentation.Lexgridschema_ v21Editor "
id="lexgridSchemaV21.presentation.LexgridSchemaV21EditorID" >
</editor>
</extension>
</plugin>
The jar file referenced (lexgrid-ui-model.editor.jar) is correct, and
does contain the class that throws ClassNotFound exception
(org.lexgrid.ui.lexgridschema_v21.presentation.Lexgridschema _v21Browser)
Can anyone give me any ideas as to what is wrong? I'm at my wits end.
Heres the stack trace, if that helps at all.
Thanks,
Dan

It turns out that the copy of eclipse that I was installing my plugin's
into must have been corrupt in some way. I started over with a clean
copy of 2.1, and things worked fine.
