Compilation of gwt project's is very slow [message #646841]

Our environment is as follows:
1. Eclipse JavaEE 3.6 with Google Web Toolkit(gwt) plugin
2. GWT 2.0.4/GWT2.1, we use UiBinder.
3. Subclipse for svn access

Whenever we change some files or fetch updates from SVN server
relating to GWT client side codes, Eclipse shows that it is building
workspace/analyzing source. But it is very slow(at least 2 minutes).

In another project, we don't use GWT and we didn't see such problems.

How can I know the detail about what Eclipse is doing during the long period?

Do you have any clues on why this happen and how to solve it?

Hi

I suggest attaching a profiler like VisualVM [1] or YourKit [2] to the
Eclipse process. Then you know exactly what happens. If that's too low
level for you, you might give the lack of progress bar plug-in [3] a chance.

[2] http://www.yourkit.com

You could try turning on the debug options for the Java builder and try to understand what is happening!
#######
Create a file called .options in the eclipse folder with the following lines in it.

org.eclipse.jdt.core/debug=true
org.eclipse.jdt.core/debug/builder=true

Then run eclipse as
%eclipsec.exe -debug
