[cbi-dev] maven error - An error occurred copying file

[Thanh Ha <thanh.ha@xxxxxxxxxxx>]

Hi Everyone,

I'm running into a strange error with maven. The error seems very 
ambiguous and I am not able to determine what is causing it. Maven seems 
to be trying to copy a file from a local repository and failing. I had a 
look in the repository and it seems the files it's complaining about 
exist so I'm not sure why there is issue. One thing I did notice however 
was when this error occurs, it seems to reset the maven build repo since 
all packages that were downloaded previously have to be redownloaded.

Has anyone ever seen this kind of problem before?

Is there anything I can do to maybe enable more logging that may help us 
figure this out?


Thanks,


Thanh
