Thanks for the reply. Yep, my mistake, apologies.

I just stuck in the string "Foo" for the SearchPattern for the purposes of
this post. What I was actually using was "a.b.c.Foo". When I use "Foo" I
am able to find all classes that extend the class Foo even though the
class Foo does not exist.

However, this does not solve my problem.

Here is my complete example:


I have a class Baz


package x.y.z;

import a.b.c.Foo;

public class Baz extends Foo{
}


which does not compile as the class


a.b.c.Foo


does not exist.


I want to do the following

(1) Find all classes that extend a.b.c.Foo
(2) Update all these classes to extend a.b.c.FooBar that does exist

But I cannot get (1) to work.


I followed your suggestion

and when using "a.b.c.Foo" as the searchPattern 'mustResolve' is indeed
set to true. However it cannot be resolved as it does not exist.

Is there any way around this i.e. is it possible to get the SearchEngine
to return all classes that extend the class a.b.c.Foo even when the class
a.b.c.Foo does not exist?


Thanks,

Máirtín
