[GWT] Plugin creates WEB-INF/lib/gwt-servlet.jar

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create non-GWT project
2. Add gwt-servlet.jar to classpath either manually or via maven/ivy
3. Enable GWT support for project

What is the expected output? What do you see instead?
Nothing should happen - gwt-servlet is in classpath. Instead, GWT plugin copies 
this file to WEB-INF/lib.

What version of the product are you using? On what operating system?
3.4.2

Please provide any additional information below.
When looking for gwt-servlet you should scan for specific class in classpath 
and ignore jar names.

gwt-servlet.jar needs to be in WEB-INF/lib in order for your application to 
work in a servlet container; putting on the build classpath is not enough. 
That's why it is automatically being copied. Is there a reason as to why you 
don't want it in war/WEB-INF/lib?

Necessary jars are provided by ivy/maven (and they have different names, most 
of it is spread across various vaadin-*.jar files).

Eclipse should absolutely not provide any jars or modify project in any way 
(except when requested by user). I have perfectly good configuration and just 
want GWT plugin features like JSNI editor.

Yes, unfortunately GPE doesn't play all that well with Maven right now. We're 
working on this problem (supporting Maven-based GWT and App Engine projects in 
GPE in the proper way). We'll have proper App Engine support this month, with 
GWT support a little after that.
