Unable to compile flashlight demo

Dalvik VM unable to locate class 'dx/dx/command/Main'
java.lang.NoClassDefFoundError: dx/dx/command/Main
at dalvik.system.NativeStart.main(Native Method)
Caused by: java.lang.ClassNotFoundException: dx.dx.command.Main

The terminal stops at 'Compiling Java...' ( I have to ctrl-c)

Suggestions?

For clarity, the error is from 'Build' button when project is open.
