I get the following error when the app rebuilds:

Errors occurred during the build.
Errors running builder 'Google App Engine Project Change Notifier' on
project 'com.eclipse.library.editor'.
NO_MODIFICATION_ALLOWED_ERR: An attempt is made to modify an object
where modifications are not allowed.

how do I remove the error?

John,

I've not seen that before. There's no associated stack trace?

Ed, there is no stack trace, or any output to the console.
