Java error: Missing proxy after upgrade 2.4 to 2.5

I have upgrade a project from 2.4 to 2.5 and get the error: .....cannot find symbol [javac] symbol : class Settings [javac] location: package modulename.proxies [javac] import modulename.proxies.Settings; I add the proxy to the folder and after compiling it works, but when I clean the deployment directory and compile it again I get the same error and the proxy is removed from the folder. What do I wrong
