@BrewTestBot test this please

The Jenkins merged build fail is caused by the svn prompt due to https certificate.
It appears that svn --force still not able to handle this case.
I'm trying to change this patch to url 'http://svn.code.sf.net/p/sdcv/code/trunk', :revision => '38'.
Any suggestion or better way about this sort of issue?
I saw a lot of formula encounter the same "not trusted authority" issue.
