#12 java.lang.ArithmeticException: / by zero

[Jan Nielsen]

It appears that if a repository has no revisions, getNumberAndPercentage will divide by zero - see below.

I do have the same problem (same stack), but my repo (SVN) HAS some revisions (443 just now). What can I do to workaround the bug?

I also have this pb. mvn site was ok and stats were generated.
Then I include some new files in svn (svn copy <url> xxx) : and since mvn site failed with / by 0.

I try with 1.1.0-SNAPSHOT version of maven stats-scm plugin, but no change.

I have to remove stats-scm from my pom...

I had seen that problem too and I had reported the bug in StatSVN. Now, I see it was created here too.
But looking at the stack trace, to me it looks more like a problem of StatSVN.
