What steps will reproduce the problem?
1.instal go binary distribuion from golang
2.install goeclipse
3.set preferences
4.new project and source file save source file

What is the expected output? What do you see instead?
I expect the code to be built and a binary module produced.
The code is not compiled, and I see this in the eclipse log:
!ENTRY goclipse 4 0 2012-09-05 17:02:24.855

I can't reproduce this, but I've recompiled GoClipse with line number 
information. Can you get the latest and attach the new NullPointerException 
stack trace to the bug? That'll let us track down the exception. Thanks!

I reproduce this issue on Windows 7 and found that it's caused by service 
"Application Experience", once this service is started, goclipse won't 
encounter this issue:)
