Error " output files to contain exactly one file, however, it contains 2 files" when running verifyMode screenshotTests about screenshot-tests-for-android

[SundeepK]

Ok after a bit of debugging, I managed to get this running again. Here's what I did:

1. In my top level build.gradle i changed classpath 'com.android.tools.build:gradle:2.2.0' to classpath 'com.android.tools.build:gradle:2.1.0'
2. Used buildToolsVersion '23.0.2' through out my gradle files.
3. Set targetSdkVersion 22 - this is ok for now since I'm working on a libaray and the sample app is using this as the target version. I know there seems to be problem with permissions targetting higher versions.

I'm not sure if my initail config was wrong (i'm a bit sketcy when it comes to gradle) or perhaps this library is incompatible but it doesn't say anything in the requirements for this. Any comments would be welcome in understanding the problem.

@SundeepK upgrade your screenshot-tests plugin to 0.4.3, this is a known incompatibility with the 2.2.0 version of the android gradle plugin. Let me know if this works.

@tdrhq I couldn't find version 0.4.3. However, version 0.4.2 seems to work fine with version 2.1.0 of the android gradle plugin.

I'll close this issue since that has resolved the problem. Thanks very much.
