It looks like in the latest Picasso Snapshot that you are using the method with hast been renamed to get see related commit here: https://github.com/square/picasso/commit/e7e919232fe2b15772a7fcd9e15ead2304c66fae
so replace with() with get() and should work.
Since you are using a not yet officially released version, there are no release notes yet, and surprizes like that can happen 😉
BTW: It seems to be a good name change to me, since a method named “with” but without parameter was a bit weird 😛
