Extension details do not get filled automatically [message #515442]

Hello,
So I provided an extension point, and when I test this in my development
environment, the extension details are filled in automatically when I
create new extension. However, if I install the plugin contains this
extension point, and test from a non-development environment, the
details are not filled in. Am I missing something in my plugin or
schema? Thanks.

Most binary plugins don't contain the .exsd schema file. In eclipse we
ship these with our .source plugins.

Without that file, you won't see anything useful in the PDE editor even
though the extension will work.

Thanks Paul,
Is there any reason why the schema shouldn't be packaged with the binary
plugin?

There's no technical reason, AFAIK. We don't do it because it would
take up space in the runtime but is not needed at runtime (only
development time), and our extensions almost always require the
contributor to implement an interface.

If the contributor needs access to the schema to fill in the extension,
they probably need access to the source so they can see the javadoc for
the interface they're trying to implement.

Imagine how hard it would be to guess why your extension isn't doing
what you want if all you see in eclipse is:
public interface IExecutableExtension {
public void setInitializationData(IConfigurationElement arg0,
String arg1, Object arg2) throws CoreException;
}
