问题
I've been getting this error, I've tried the solution stated here: Android studio - Failed to complete gradle execution - error in opening zip file
This error is killing me, I've tried removing the .gradle folder. I've noticed that the .idea\libraries folder has a bunch of xml's in it and I've tried deleting that (thinking its storing something wrong) and that wasn't it either.
I've narrowed it down to the jars downloaded from the espresso-android site, espresso-1.1.jar and the test runners - I've verified that without them in the dependencies it works. And as soon as they've been added it doesn't. I can even add other dependencies and it works. So I don't know why these Jars are the exception but they don't work.

回答1:
The problem, I found, was that I was downloading the jars from the espresso site : https://code.google.com/p/android-test-kit/source/browse/#git by right clicking on them and clicking 'Save as'- which did indeed download the jars, they just did not work for some odd reason. Even repeating this, they still did not work - I checked that I had permission (since I have a mac and its a bit touchy).
I had to download all of the files as a zip, unzip the whole thing, and hand pick and drag all the jars I needed out of their respective folders.
Edit: 
you'll see the 'download zip' in the bottom right of the screen grab. That is what I clicked and unzipped for the working jars.
