Depending on the type of bundle being developed, it may
have a different set of dependencies than the ones
required by this 'simple' validator. However the
configuration approach will be the same.

Go to the META-INF/MANIFEST.MF file
and select it. This will cause the plugin manifest
editor to be displayed.

Select the Dependencies tab and
select the other bundles that will be required, or
preferrably select the packages to be imported (as this
avoids dependency on specific bundles, and instead
just identifies the packages required). For this
example validator, we just need to add the packages
from the org.scribble.common bundle
which is used by all Scribble plugins. However if
additional packages were required, then they could be
added as imported packages (e.g. org.scribble.protocol.model
and org.scribble.protocol.validation).
